16 CPC Operations Manual Run Operations Page # Run Operations This chapter discusses the following topics: Run Operations screen contents How to setup and start a run. Overriding the run Taking manual control of the process Disabling thermocouples during the run

17 Different versions of the Run Operations screen CPC Operations Manual Run Operations Page #2-2 This manual uses a typical Run Operations screen example (shown on previous page) to describe all Run Operations procedures. Due to varying customer and system requirements, it is probable that your Run Operations screen will differ from the screen shown in this manual. These differences may include addition or deletion of steps, operation buttons, parameters, and capabilities. Notwithstanding these differences, the information that is provided in this chapter should be easily understood and useful to your specific system requirements. Run status information The Run Operation screen shows the following information. Run Recipe This defines the Recipe that has been selected for the current or next run. Run Status This shows the running status of the run. This display will either show OFF or RUNNING. Note: Some systems will blink this entry when the run is in progress. Segment Information The recipe segment # and segment comment for the current segment is displayed here. If a run is not in progress this information displays the last segment of the previous run. Hold status This identifies the current Hold status of the run. During a Hold condition the system s run timer is paused and all setpoints are maintained at theire current values. The possible Hold values are Off, Manual, or System. Manual Indicates a manual hold. System Indicates a system generated hold. Wait status This identifies the current Hold status of the run. During a Wait condition the system s run timer and setpoint operations continue normally, but the run is disallowed from moving to the next segment. The possible Hold values are Off, Manual, or System. Manual Indicates a manual wait condition. System Indicates a system generated Wait condition. This is generally created by the Watch group function in the Recipe. Time in Run This indicates the current elapsed run time in Hours, Minutes, and Seconds. Time in Segment This indicates the current elapsed segment time in Hours, Minutes, and Seconds.

18 CPC Operations Manual Run Operations Page #2-3 Segment Time Left This indicates the time remaining prior to reaching the end of the current segment. This value will remain at 0S (0 seconds) whenever the system is placed in a Wait mode by the Watch group function. In this condition the system remains at the end of the segment, but is disallowed from changing to the next segment. Data saving information The following information is provided to describe the data saving during the run: Datafile Name If a run is in progress, this name indicates the path and filename of the datafile that will contain the run s data. If a run is not in progress, this name indicates the prior run s file. There are many different naming conventions used on CPC systems. The most common naming convention includes the equipment, date, and run index of that date. For example: 1 st run of 10/28/99 for Autoclave #AC3 = AC3_ DAT The second most common naming convention uses a prefix followed by a sequential index. For example: 503 rd run for Autoclave #4 = AC4-503.DAT Other naming conventions are customer-specific. Data Interval This indicates the time interval used to save the input values to the datafile. This is typically 1M or 5M and must be entered in order for data to save properly. Integrity check information Integrity checks are an automatic check of the parts, part attachments, thermocouples, and vacuum integrity prior to starting a run. Checks Status This indicates whether the Integrity Checks have passed or failed. The possible values are PASS, FAIL, or OFF. Note: On some systems the Checks must PASS or be manually bypassed prior starting the run. Integrity Checks Bypassed This toggle is used to manually bypass the run s integrity checks interlock. In some systems, the Checks must PASS prior to starting the run. In the case of a failure, you can manually bypass this interlock. System information Depending on the system and CPC installation, the following information may be provided: System Status This indicates whether all of the hardware systems are properly enabled prior to starting the run. This indication is only displayed to systems that have pre-run requirements (e.g. Vac Pumps must be on).

19 Run Status CPC Operations Manual Run Operations Page #2-4 This indication is provided on systems that utilize integrity checks and pre-cure abort limits. In these installation the Run Status will indicate one of the following conditions: STANDBY Ready to receive setup information for next run. READY Integrity checks are complete and all systems are ready to start the run. PRECURE Running and all part temperatures are below precure limit. CURE Running and part(s) have entered cure. Precure Status This indication is used on systems which utilize the Precure Limit parameter in the recipe. Precure Status will be either BELOW PRECURE or ABOVE PRECURE. Calibration status Calibration due date information is displayed for the specific types of sensors. This information is utilized only on systems which have been pre-configured to disallow run operations whenever calibration expires. Note: This indication will blink when the calibration is within 3 days of expiration. How to setup and start a run The run setup procedure is typically numerically identified on the Run Operations screen. Note: Your procedure and steps may differ from the example used in this manual. Setup Vacuum This step sends you to a version of the vacuum operations screen. On this screen you will: Turn on the vacuum pump(s). This is applicable only on systems with vacuum pump controls. Set and check the vacuum header levels that you want the parts to be connected to (e.g. 30 Hg) Open the vacuum source lines that you will be using for the part connections. Note: This step will only be used on systems which have automatic vacuum line controls. Enter Load Number This step is a manual entry of a load or run number. This manual step is only provided on systems that require Load Number tracking. Select Recipe This step will access the Recipe Operations screen where you will perform the following operations (See Recipe Operations chapter for more information): Browse and View the Recipe that you want to run. Click the Transfer to Equipment button to select the recipe for the run. Note: Once the recipe is transferred you may choose to modify the run-recipe.

20 Enter Parts CPC Operations Manual Run Operations Page #2-5 This step will access the Batch Entry screen where you will enter part information for the run (See Batch Entry Operations chapter for more information). Verify sensors Delete the previous batch Enter parts for the current run, including part information and part attachments such as thermocouples, vacuum sources, and vacuum probes. Perform preliminary leak checks on each individual part (optional). This step will access the Sensor View screen (See Viewing Screens chapter for more information). Check that the primary sensors (e.g. air temp, pressure, vacuum) are reading and enabled. Check that all attached part thermocouples are enabled reading acceptable temperature values. Check that all attached vacuum probes are enabled and reading acceptabl e vacuum values. Integrity Checks This step will access the Integrity Checks form. Note: This form will float over the screen, allowing you to access the Verify Sensors screen in order to view the sensor values during the test.

21 The following buttons are provided: Start to commence the automatic integrity check process. Stop to prematurely stop the check process. View to access the visual report of the integrity check results. Print to print the integrity check results. CPC Operations Manual Run Operations Depending on the specific configuration of your system, one or more of the following checks and verifications will be performed: TC Check Page #2-6 Check whether all attached part thermocouple readings are within an acceptable range (e.g F) Check whether the primary thermocouple (e.g. Air Temperature) reading is within an acceptable range. Probe Check Check whether the minimum number of probes are attached to each part. Note: This quantity information can be identified in the Part Database. Set Status to OK or FAIL. Probe Check Check whether the minimum number of probes are attached to each part. Note: This quantity information can be identified in the Part Database. Set Status to OK or FAIL. Header Check After a predefined time period, check whether the vacuum headers are within an acceptable deviation from the Header setpoint(s). Set Status to OK or FAIL. Drawdown Check After a predefined time period, check whether all vacuum probe readings are within anacceptable deviation from the vacuum header readings. Note: This confirms that all parts have pulled-down to the header vacuum. Set Status to OK or FAIL. Leak Test Read and record the vacuum readings of all vacuum probes. Isolate the source lines on all parts. After a pre-configured time period, read and compare the current vacuum readings with the initial vacuum readings. Identify and display the sensors and parts which have exceeded a pre-configured leak test limit. After a predefined time period, check whether all vacuum probe readings are within anacceptable deviation from the vacuum header readings. Note: This confirms that all parts have pulled-down to the header vacuum. Set Status to OK or FAIL.

22 Start Run CPC Operations Manual Run Operations Page #2-7 This step will initiate a run. Prior to starting the run the system will display a confirmation form to verify your intent. Depending on the specific system installation, the following interlocks may disrupt the run intiatiation process: Integrity Checks are failed and the checks are not bypassed. Hardware systems are not ready (e.g. Door not closed). What happens when the run starts? The following system functions are performed at run commencement: Last run s alarm and system messages are deleted from the Message Screen. The datafile name is incremented and a new file is created on the primary and backup PC. Initial data records are recorded to the new datafiles, including part information, sensor information, run information, and initial messages. Records are written to the RunDatabase on the primary and backup PCs. These records are used for post-run analysis and include run information (e.g. StartTime, # of Parts, # of TCs, etc.), Part Information, Tool Information, and Sensor Attachment information. Temperature, pressure, vacuum, and similar control modes are set to Auto. Fan, pumps, and other hardware control modes are set to Auto. Load Number is incremented. Recipe processing is initiated. Segment is set to #1 for the currently transferred recipe. Current segment s parameters are loaded into the Recipe Processor. What happens during the run? The following system functions are performed during the run. The Recipe Processor calculates the timing, setpoints, and other functions according to the selected recipe and segment s parameters. The system controls temperature, pressure, vacuum, and all other functions and components according to the recipe or automatically generated setpoints. Numeric sensor data is written to the datafile at the pre-configured data intervals and at segment changes. All messages are written to the datafile at activation. Run Database message records are written at each segment change.

23 CPC Operations Manual Run Operations Page #2-8 Run override controls The following buttons are provided for manual override of the automatic run. Change Segment Click this button will force the run to automatically change to the Next or specified segment. You can change the selected segment by clicking on the Segment to change to pulldown menu. The system will display a confirmation form prior to carrying out a manually initiated segment change. Manual Hold Depress this button to enable a Manual Hold condition. Release this button to return the run to a normal (non-hold) status. End Run Click this button to end the current run. This end run operation is non-recoverable and will cause the system to stop the recipe processing, close the datafile, write the run database, and return the pre-configured systems to a neutral setpoint and condition. The system will display a confirmation form prior to carrying out this end run operation. Abort Run This button is provided to customer that require a specifialized abort procedure. An abort procedure is normally performed in order to repair a leaking bag, and must be initiated prior to the parts reaching cure. In an abort operation the run and recipe is halted, but data collection continues. Taking manual control of the process You can take manual control temperature, pressure, vacuum, fan, and valving as allowed. See Viewing Screens chapter for details about your manual screens. 1.) Access the applicable Manual Operations screen. Note: On some larger systems, the manual operations are separated into multiple screens. 2.) Click the Man or SemiAuto selection for the specific control element or item that you want to take control. The system will display a confirmation form prior to changing to the specified mode. Any change to a control mode during the run will result in a Manual (green) message being written to the datafile. This message will indicate the PC, operator id, and operation that was performed.

24 Disabling thermocouples during the run CPC Operations Manual Run Operations During the run, the system will automatically disable thermocouples that do not pass a validation test. Once disabled the thermocouple will not be utilized for HITC and LOTC calculations, control, or recipe Watch functionality. The following procedure can be used to manually disable or enable a thermocouple: 1.) Access the Sensor View screen. Page #3-9 2.) Click the specific sensor that you want to disable/enable. The system will display a Quick View form for that sensor. 3.) Depress Enable or Disable to set the sensor. The Status will change to either Man-On or Man-Off. 4.) Close the Quick View form by clicking the X in the upper-right. 3. Recipe Operations This chapter discusses Recipe Operations in the Recipe Editing screen. The following topics will be covered: What is a Recipe and how does it operate How to select a recipe for viewing/editing How to create or modify a Recipe How to verify if a Recipe will run correctly

25 How to select a Recipe for the run CPC Operations Manual Recipe Operations Page #3-2 This is the general information for the displayed Recipe. This is the Recipe that was transferred to the equipment for the next run. Recipe currently displayed for editing. This is a segment comment for Seg#1. This spreadsheet displays the Recipe s contents. What is a Recipe? A Recipe is a step-by-step procedure that is programmed to automatically duplicate the steps required to process the parts in the equipment or the control the equipment in general. The steps in a Recipe are referred to as Segments. Each option within a segment is referred to as a Parameters. Multiple parameters that work together are referred to as Groups. Segment defined A segment is generally a unique control step for the Recipe. In practice a new segment is utilized whenever a change occurs in the process. For example, if you want a vacuum pump to turn off at a specific point in the run/recipe, then you would create a new segment at that point and set the Vacuum Pump parameter to OFF. Parameter defined Recipe parameters are individual options which serve to provide a control state or recipe function during the run. Some parameters work independently, and others are grouped together to provide a recipe Group function. Parameter contents may be typed directly into the spreadsheet form, or they can be selected from pull-down listings.

26 Group defined CPC Operations Manual Recipe Operations Page #3-3 A recipe group is a set of parameters that are used for a specific function. For example, a ramp/soak group provides a Rate and a Value parameter. Both of these parameters are required in order to define the Ramp and Soak operation. See Pressure Rate and Pressure Value above. In the Recipe Editing Screen the parameters within a given recipe group are shaded similarly. How a recipe operates The recipe becomes operational whenever the equipment operator Starts a Run. A Run is an automatic recipe controlled process. Start of run At the start of a run the system will perform the following steps: Resets the segment pointer to Segment #1. Reset all run timers. Scan segment #1 of the recipe and transfer all parameter settings to the specific control groups. Begin cyclical operations. Cyclical operations Once a run is started the system will perform the following cyclical recipe processing steps: Trigger the calculations for all control groups. For example, this calculation includes the ramping function for a temperature, pressure, or vacuum control loop. Trigger the alarm calculations for all recipe parameter alarm groups. Trigger the calculations for all Watch groups. Check the segment timer and if the elapsed time has exceeded the programmed Segment Time and if the Watch groups are not suppressing a segment change, then change to the next segment. At segment changes At a segment change the system will perform the following steps: End of recipe Scan the new segment of the recipe and transfer all parameter settings to the specific control groups. Check for the END setting in the Segment Time. If END then initiate a recipe end procedure. Begin cyclical operations. A recipe end is indicated by one of the following two forms: An END setting was entered in the segment s Segment Time parameter. No more segments in the recipe. At the end of a recipe/run the system will perform the following recipe processing steps: Stop the cyclical operations of the recipe processor.

27 Selecting a recipe for viewing or editing CPC Operations Manual Recipe Operations Page #3-4 Use the recipe selection tree to select a recipe for viewing. The tree (shown below) will contain all programmed recipes as well as the recipe copy used for the next (or current) run. Click here to view and/or edit the run-recipe. Click on a Recipe to select it for viewing/editing. Restricted recipe. Recipes Folder The main Recipes folder will contain all programmed and stored recipes, as well as other sub-folders used to organize recipes of a specific type. Equipment Folder The Equipment folder will contain a sub-folder with the name of the specific equipment that you are programming for. In the above example the equipment is called Autoclave. The recipe stored under the Autoclave folder is the recipe that will be used for the next (or current) run. This recipe is always a copy and/or derivative of a recipe stored in the Recipes folder. Selecting a recipe CPC differs from other systems in that it does not require you to load a file from disk in order to view and/or edit a recipe. In CPC all the recipes are always loaded into memory and are readily available. Single-click the recipe s name in the tree to select it for viewing. The spreadsheet will display the contents of the recipe. The tab window in the upper-left will display the recipe s information. Restricted recipes An X selection in the recipe tree indicates a recipe that has been restricted for use in the current equipment. This restriction indicates that the recipe has been configured (Equipment property) to run on a specific piece of equipment or a series of equipment only. Note: You can change this restriction by accessing the CPC Object Editor and either deleting the Equipment property or adding your equipment to the Equipment property of the specified Recipe object. This normally requires supervisor security access.

28 Selecting the run recipe CPC Operations Manual Recipe Operations Page #3-5 The run-recipe is the recipe that will be used for the next run or is being used for the current run. This recipe is a copy or a changed copy of one of the recipes stored in the Recipes folder. To view this run recipe click the recipe displayed below the specific equipment folder (i.e. Autoclave). Selecting a recipe for the next run The following procedure is used to select a recipe to be used for the next run. This procedure is required prior to starting a run, except in the case where the system has automatically selected the recipe based on the parts that have been entered into the batch (part database feature). 1.) Single-click on the recipe that you want to run. 2.) Click the Transfer to Equipment button. This will automatically copy the selected recipe and transfer the copy to the specified equipment folder. Note: You can confirm the transfer by clicking on the run-recipe displayed below the equipment folder. Recipe information defined Each recipe has the following information that can be viewed and/or changed on the Recipe Editing screen. Recipe name This is the name of the recipe. The recipe name must not include periods(.), backslashed (\), or colons (: ) FilePath This is actually an internal object path for the recipe not a actual file path. Each folder is delineated by a \ character. This path is automatically created by the system whenever you create or change the name or location of a recipe. Note: An object path represents a location within the CPC s main object structure. As discussed earlier in this chapter recipes are stored internally in memory and not in individual files.

29 CPC Operations Manual Recipe Operations Page #3-6 Description This is text description of the recipe. Unlike the recipe name parameter, the description can include any character. It is recommended that the description provide general information about the process rather than a repeat of the recipe s name. Specification This is the process specification that the recipe is programmed for. Though this parameter is optional, it is recommended that you use it if you want to be able to perform fielded-searches and queries of the post-run database (i.e. SPC queries and reports). Equipment This parameter can be blank or can include a list of equipment that can use this recipe. If a list is entered the system will restrict incompatible equipment from being able to use or edit this recipe. This parameter is generally used only on multi-equipment control systems where completely different types of equipment are controlled (i.e. oven, autoclave, press, etc.) A restricted recipe is displayed with an X in the recipe tree. Revision This parameter tracks the revision number or letter used to identify this version of the recipe. It is normally entered automatically by the recipe editing screen whenever you create a new revision (New Revision button). Revised date This date is automatically generated when a new revision is created with the New Revision button. Modified date This date is automatically generated whenever the recipe s contents or recipe s information is modified. Last Run date Author This date is automatically updated whenever the recipe is run. This is the name of the recipe programmer who created this recipe or the recipe revision. Comments This is a comment describing the recipe and/or revision. Recipe parameters defined CPC can control a wide variety of equipment and processes. Due to this variety the recipe structure and the specific parameters on each system will differ greatly. Because it is not possible to document in one manual all of the differences from one system to another, a list of the most common recipe parameters is provided in the Recipe Parameters chapter of this manual. Note: Any other customized parameters that may be included with your system and not documented in this manual will usually be documented in the help screens for the specific system.

30 How to create a new recipe The following procedure is used to create a new recipe: CPC Operations Manual Recipe Operations Page #3-7 1.) Click and select a recipe in the tree. The new recipe will be added after the selection. 2.) Click the Add Recipe button. A new recipe will be created it will be automatically named Recipe. 3.) Now select and change the recipe name by editing the Recipe property in the left-hand tab window. 4.) Enter the Description, Specification, Author, and Comments fields as required 5.) Now click the Add Segment button to add some segments. Once the segments are created, you can begin to edit the recipe. How to create a copy of an existing recipe Once some standard recipes are programmed (i.e. single-ramp, double-ramp, etc.) it is recommended that all subsequent recipes be modified copies of these standard ones. This reduces the possibility of programming mistakes. 1.) Select the source recipe in the tree. 2.) Right-click on that recipe selection to access the pull-down menu. 3.) Select Copy from the menu. 4.) Now select the recipe that you want to precede the newly copied recipe. 5.) Right-click on that recipe and select Paste from the dropdown menu. The new recipe will be created and its name will be the same as the source plus an ind ex number. For example, TEST recipe will be copied to TEST1. 6.) Now select and change the recipe name by editing the Recipe property in the left-hand tab window. 7.) Modify the Description, Specification, Author, and Comments fields as required 8.) Now change the recipe s parameters as required. How to delete a recipe Deleting a recipe is a non-recoverable operation. 1.) Click the recipe on the tree that you want to delete. 2.) Now right-click the recipe and select Delete from the pull-down menu. You can also press the Delete button (later versions of software). 3.) A warning message will request confirmation. Answer YES to delete. How to edit a recipe The following section discusses editing operations. Security requirements On most systems recipe editing is locked from Operator access. In these configurations an Engineer or Supervisor membership is required. Note: There is a method of securing the main recipes (i.e. Recipes folder) and unlocking the run-recipe editing operations. This is useful if you want the operators to be able to modify a run s recipe without modifying the original recipe.

31 Adding, inserting, or deleting segments CPC Operations Manual Recipe Operations You can click the Add Segment, Delete Segment, or Insert Segment buttons to increase or decrease the number of segments in a recipe. Page #3-8 Add Segment will add a segment after the currently selected segment. Insert Segment will add a segment before the currently selected segment.

33 How to verify a recipe CPC Operations Manual Recipe Operations Page #3-10 CPC has a recipe preview capability which simulates a run and shows the results of the run. The results of this simulation are displayed in trend form, providing you the opportunity to analyze the run and make changes to your recipe as required. Note: The system will not tell you if there are problems. It will only show the results of the simulation. It is your job to analyze the results and determine if there was a problem.

34 Modifying the run-recipe before the run CPC Operations Manual Recipe Operations Page #3-11 As discussed earlier in the chapter the run-recipe is the recipe that will be used for the next run or that is being used for the current run. This recipe is a copy or a changed copy of one of the recipes stored in the Recipes folder. In many cases it is useful to change the run-recipe prior to starting a run. This operation will modify only the running copy of the original recipe without changing the original recipe in the Recipes folder. Note: proper security is required. 1) Select a recipe for the next run (see procedure earlier in chapter.) 2) Now click and select the transferred run-recipe on the tree 3) Modify the recipe as required The system will display a warning confirmation message upon leaving the screen or clicking on another tree entry. Click YES to this confirmation to complete the change. Modifying the running recipe on the fly The CPC system provides an easy means of modifying the running recipe during the run. This operation is useful during experimental and developmental cycles in order to quickly tweak the process. You can change the current segment or any subsequent segments. 1) Access the recipe editing screen 2) Now click and select the run-recipe on the tree (see procedure earlier in this chapter) 3) Modify the recipe as required The system will display a warning confirmation message upon leaving the screen or clicking on another tree entry. Click YES to this confirmation to complete the change

35 CPC Operations Manual Recipe Parameters Page # Recipe Parameters This chapter describes the recipe parameters used in standard CPC applications.

36 CPC Operations Manual Recipe Parameters Page #4-2 Segment Time Units: Time in the form xxm, xxh, or xxs Description: Usage: Segment time defines the minimum time length of a segment. The time of a segment begins the moment the segment becomes active. The following example shows a recipe sequence that turns a pump on for 2 minutes, off for 30 minutes (1/2 hour), then back on for 30 seconds. Seg1 Seg2 Seg3 Seg4 Segment Time 2M.5H 30S Pump #1 ON OFF ON 4-2

37 CPC Operations Manual Recipe Parameters Page #4-3 Temp Control TC Units: Tag name of an input sensor (ie. HITC, LOTC, TC121, etc.) Applies to: Part temperature control applications using cascade or Air temperature control using no cascades. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter defines the thermocouple that will be controlled during the segment. If the thermocouple selected is a part thermocouple or part thermocouple derivation (ie. HITC) then the system will utilize cascade settings (Cascade In and Cascade Out) to drive the primary sensor (usually AIRTC or similar) to a temperature which will in turn control the selected sensor to the programmed rate and final target value. The following example shows a typical cascade control program. In this case, the highest part thermocouple is heated at 5 deg/min to 350 deg. The cascade settings request an out-to-in ratio of 100:50 or 2 to 1 (2 degf air temperature change for each 1 degf part temperature deviation from setpoint). The Cascade Out of 100 provides an overall limit to the amount of air temperature overshoot that will be tolerated (100 degf above setpoint max). Once the lowest part thermocouple has reached 340 F, the program will move to segment #3 and begin a 2 hour hold (or soak). After the hold segment, the program will move to segment #4 and switch control to the lowest thermocouple at maximum rate to 100 degrees (attempted target). When the highest part thermocouple reaches 150 deg., the system will move to the next segment. Seg1 Seg2 Seg3 Seg4 Segment Time 2H Temp Control TC HITC LOTC Temp Rate 5 X Temp Value CURR Cascade In 50 Cascade Out 100 Watch Item #1 LOTC HITC Criterion >340 <150 Action GO GO 4-3

38 CPC Operations Manual Recipe Parameters Page #4-4 Temperature Rate Units: F/min or X for infinite (or maximum) rate. Applies to: Part temperature control applications using cascade control. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter defines the ramping rate for the temperature control group. During a run, the system will attempt to ramp the selected control thermocouple (Control TC parameter) at this rate toward the target value (Temp Value parameter). Refer to Usage section for Temp Control TC on the previous page. Always enter a positive value for rate, even in a cooling segment. If you want the system to immediately change to the target value, enter an X to block the pass-through and request an infinite rate. 4-4

39 CPC Operations Manual Recipe Parameters Page #4-5 Temperature Value Units: F or CURR for current temperature. Applies to: Part temperature control applications using cascade control. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter defines the target temperature for the selected control thermocouple. The target is independent of the actual segment, and is only dependent on the programmed rate. Refer to Usage section for Temp Control TC on the previous page. Entering CURR will instruct the system to enter the current thermocouple temperature as the target setpoint this is used primarily in segment #1 to initiate the temperature control group. The dependent on the ramp rate and is entirely independent of the segment. For example, a ramp from 70 to 400 at 5 deg/min can span many segments. Always initiate the temperature control on Segment #1 with an initial temperature (ie. CURR or 80) and an infinite rate (X). This will force the system to start ramping from an ambient temperature rather than from 0 deg.f. 4-5

40 CPC Operations Manual Recipe Parameters Page #4-6 Cascade In Units: F (part temperature deviation), or X for canceling the cascade function. Applies to: Part control applications using cascade control. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter is used in conjunction with the Cascade Out parameter to define the mathematical gain of the cascade control function. Cascade control refers to the method of controlling one thermocouple by regulating the temperature of another. In the autoclave application the air temperature is regulated in order to drive a part thermocouple toward a selected target setpoint. In CPC the system uses Cascade In and Cascade Out to determine the air cascade temperature setpoint. The following calculation is used: AirSetpoint = PartSetpoint + (CascadeOut / CascadeIn) x (PartSetpoint PartTemp) As you can see the air temperature setpoint is equal to the current part setpoint plus a value which is derived from the current part temperature deviation and the ratio of Cascade Out to Cascade In. In the above equation the Out-to-In ratio can be described as the amount of air temperature overshoot to part temperature deviation. Warning: Refer to Usage section for Temp Control TC on the previous page. In this example, the system will adjust air temperature 2 degrees for each 1 degree change of part temperature. If an X is entered in either the Cascade In or Cascade Out parameter, the system will cancel the cascading and formulate an air temperature setpoint equal to the current part temperature setpoint. This has the same affect as setting the Temp Control TC parameter to AIRTC. Be careful when sizing the cascade parameters. Because during cascade control the air temperature relates the part temperature, a high Out-to-In ratio coupled with a noisy part thermocouple (or thin part) can cause an unstable condition. For most cases we suggest a maximum out-to-in ratio of 3:1 (ie. CascadeOut = 150 and CascadeIn = 50). 4-6

41 CPC Operations Manual Recipe Parameters Page #4-7 Cascade Out Units: F (air temperature overshoot), or X for canceling the cascade function. Applies to: Part control applications using cascade control. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter is used in conjunction with the Cascade In parameter to define the mathematical gain of the cascade control function. See Cascade Out description on previous page. Warning: Refer to Usage section for Cascade In on the previous page. In this example, the system will adjust air temperature 2 degrees for each 1 degree change of part temperature. If an X is entered in either the Cascade In or Cascade Out parameter, the system will cancel the cascading and formulate an air temperature setpoint equal to the current part temperature setpoint. This has the same affect as setting the Temp Control TC parameter to AIRTC. See Warning for Cascade In on the previous page. 4-7

42 CPC Operations Manual Recipe Parameters Page #4-8 Add Per Time Units: F air temperature change per F part temperature delta per minute. Applies to: This parameter is rarely used, and applies only to part control applications that meet the following prerequisites: Pass-through: Use in heating applications where due to poor equipment temperature uniformity conditions the part temperatures do not naturally converge on the air temperature. Use in heating application where you want the part temperature to catch up to the target setpoint during ramping operations. This requirement is rare due to the fact that, in order to catch-up, the part temperature rate will exceed the requested rate. Value will automatically pass to subsequent segments until changed. Parameter description: This parameter enables an integration function that serves to increase (or decrease) the air temperature setpoint based on the part temperature deviation as well as the amount of time that the part has deviated. It is an additive function that, unlike the cascade amplification, will retain the air temperature overshoot once the part temperature reaches the setpoint. The following equation applies: AirTempSP = AirTempSP + AddPerTime x (PartSP-PartTemp) / TimeIncrement 4-8

43 Usage: CPC Operations Manual Recipe Parameters Page #4-9 The following example shows how to use Add Per Time in a typical cure application. This recipe waits till the controlling thermocouple is near the final setpoint (Segment #2 watch) before enabling the integration function. Once enabled, the system will add.2 deg.f every minute to air temperature for every 1 deg. Part deviation (ie. if the part is deviating 10 degf, the system will add 2 deg/min to air temperature). The integration is maintained during the soak period and then disabled during cooling. Note: It is imperative that you disable the integration at the beginning of any ramp. Segment Time Seg1 Seg2 Seg3 Seg4 Seg5 Temp Control TC HITC LOTC Temp Rate 5 X Temp Value CURR Cascade In 50 Cascade Out 100 Add Per Time.2 X Watch Item #1 HITC LOTC HITC Criterion >340 >340 <150 Action GO GO GO 2H Refer to Usage section for Cascade In on the previous page for more information. Warning: Because the integration function adds a value based on the current part temperature deviation, it should only be enabled after the control thermocouple has reached a close proximity to the soak temperature. Due to its additive nature it is easy to oversize the Add Per Time parameter, causing an unstable condition. We suggest a value range of.1 to.5 degf/degf/min. 4-9

44 CPC Operations Manual Recipe Parameters Page #4-10 Pressure Rate Units: Psig/Min or X to stop pass-through and request an infinite (maximum) rate. Applies to: This parameter is used with the Pressure Value parameter in autoclave, platen press, and other pressure related applications. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter defines the ramping rate for the pressure control group. During a run, the system will attempt to ramp the pressure setpoint at this rate toward the target value (Pressure Value parameter). Always enter a positive value for rate, even in you are requesting a depressurization action. If you want the system to immediately change to the target value, enter an X to block the pass-through and request an infinite rate. The following example shows a typical pressurization example: This recipe requests a 5 psig/min pressurization to 90 psig. A watch group is utilized to confirm that 90 psig is achieved (>89) prior to entering the next segment. After remaining in segment #2 for 20 minutes, the system will request maximum depressurization to 0 psig, confirming this action with another watch group. Note: Watch group parameters do not pass-through that is why PRESS is entered twice. Segment Time Seg1 Seg2 Seg3 20M Pressure Rate 5 X Pressure Value 90 0 Watch Item #1 PRESS PRESS Criterion >89 <1 Action GO GO 4-10

45 CPC Operations Manual Recipe Parameters Page #4-11 Pressure Value Units: Psig, or CURR for current pressure. Applies to: This parameter is used with the Pressure Rate parameter in autoclave, platen press, and other pressure related applications. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter defines the target pressure for the pressure control group. The target is independent of the actual segment, and is only dependent on the programmed rate. Refer to Usage section for Pressure Rate on the previous page. Entering CURR will instruct the system to enter the current pressure as the target setpoint this is used in applications where you want the system to maintain the current pressure during a heating or co oling phase. The dependent on the ramp rate and is entirely independent of the segment. For example, a ramp from 0 to 200 Psig at 5 psig/min can span many segments. 4-11

46 CPC Operations Manual Recipe Parameters Page #4-12 Header #1 Rate Units: Hg/Min or X to stop pass-through and request an infinite (maximum) rate. Applies to: This parameter is used with the Header #1 Value parameter to control the vacuum header #1. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter defines the ramping rate for the vacuum header control group. During a run, the system will attempt to ramp the vacuum setpoint at this rate toward the target value (Header #1 Value parameter). Always enter a positive value for rate, even in you are requesting a drop in vacuum. If you want the system to immediately change to the target value, enter an X to block the pass-through and request an infinite rate. In applications with multiple part vacuum sensors, you can utilize the HIPRB or LOPRB entries in the watch group to insure that all part vacuums have reached a predetermined vacuum level. Note: The PRB designation may be different (ie. VAC or MON) on your system. Remember that the vacuum value is entered as a negative number (pressure is positive). This affects the direction of the watch criterion. The following example shows a recipe that cycles vacuum with an intermediate dwell: This recipe requests an immediate full-vacuum level (-30 Hg). A watch group is utilized to confirm that all part vacuums have achieved at least -25 Hg. After remaining in segment #2 for 10 minutes, the system will request a slow 1 Hg/min venting to a fully vented condition. A watch group confirms that all parts have dropped to the vent condition.

Parameter description: Usage: This parameter defines the target pressure for the pressure control group. The target is independent of the actual segment, and is only dependent on the programmed rate. Refer to Usage section for Header #1 Rate on the previous page. Entering CURR will instruct the system to enter the current system vacuum as the target setpoint this is used in applications where you want the system to maintain the current vacuum level at some predetermined event. 4-13

Applies to: This parameter is used with the Header #2 Value parameter to control the vacuum Header #2. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter defines the ramping rate for the vacuum header control group. During a run, the system will attempt to ramp the vacuum setpoint at this rate toward the target value (Header #2 Value parameter). Always enter a positive value for rate, even in you are requesting a drop in vacuum. If you want the system to immediately change to the target value, enter an X to block the pass-through and request an infinite rate.

Applies to: This parameter is used with the Header #2 Rate parameter in autoclave and oven applications. Pass-through: Value will automatically pass to subsequent segments until changed. Parameter description: Usage: This parameter defines the target pressure for the pressure control group. The target is independent of the actual segment, and is only dependent on the programmed rate. Refer to Usage section for Header #1 Rate on the previous page. Entering CURR will instruct the system to enter the current system vacuum as the target setpoint this is used in applications where you want the system to maintain the current vacuum level at some predetermined event. 4-15

50 CPC Operations Manual Recipe Parameters Page #4-16 Watch Item Units: Tag name of input sensor (ie. HITC, LOVAC, PTC1, VPRB1, etc.) Applies to: This parameter is used with the CRITERION, ACTION, and TIME parameters to define a Watch Group. It is utilized in all applications that require a guaranteed action. Pass-through: Value will NOT automatically pass to subsequent segments. Parameter description: Usage: This parameter identifies the sensor that will be watched during the specific segment in order to provide a guarantee of outcome prior to moving to subsequent segments. The entry must be a legitimate input sensor (Inputs collection) or derived input value (ie. HITC). Watch Group parameters do not pass through to subsequent segments. For this reason, you will need to repeat the Watch Item is you wish to watch the same neighboring segments. The following example shows a cure cycle that utilizes watch groups to confirm temperatures and pressures during the run.

51 CPC Operations Manual Recipe Parameters Page #4-17 Watch Criterion Units: Logical comparison in units of the watched item (ie. >100, <2, =5) Applies to: This parameter is used with the ITEM, ACTION, and TIME parameters to define a Watch Group. It is utilized in all applications that require a guaranteed action. Pass-through: Value will NOT automatically pass to subsequent segments. Parameter description: Usage: This parameter identifies the comparison that will be utilized to determine whether the watch action should be taken. The units of the comparison are in the same units as the watched sensor item. The following comparisons are recognized: > Greater than < Less than = Equal To <> Not equal to >= Greater or equal to <= Less than or equal to See Usage section of Watch Item on previous page for example. Watch Group parameters do not pass through to subsequent segments. For this reason, you will need to repeat the Watch Item is you wish to watch the same neighboring segments. 4-17

52 CPC Operations Manual Recipe Parameters Page #4-18 Watch Action Units: Action statement: GO, HOLD, WAIT, TSTOP, or ALARM. Applies to: This parameter is used with the ITEM, CRITERION, and TIME parameters to define a Watch Group. It is utilized in all applications which require a guaranteed action. Pass-through: Value will NOT automatically pass to subsequent segments. Parameter description: This parameter identifies the action that will be taken if the watch item meets the criterion comparison. The following actions are recognized: GO A watch group with this action is enabled only at the end of the segment (after segment time is elapsed). This action causes the system to move to the next segment only if the watch item s value meets the criterion (ie. true condition). Note: This action will not stop (or hold) ramping operations. WAIT A watch group with this action is enabled only at the end of the segment (after segment time is elapsed). This action causes the system to wait in the current segment as long as the watch item s value meets the criterion (ie. true condition). This is the opposite of the GO action. Note: This action is different than a HOLD operation. HOLD A watch group with this action is enabled throughout the entire segment. This action causes the system to invoke an auto-hold of the process as long as the watch item s value meets the criterion. Note: An auto-hold does the same thing as a manual-hold - all ramping operations stope and the segment timer holds at its current position. TSTOP A watch group with this action is enabled throughout the entire segment. This action causes the system to stop the segment timer as long as the watch item s value meets the criterion. It is generally used for guaranteed soak applications. AND OR Usage: You can link two watch groups using the AND action. When two watch groups are linked together with AND, they both must be true prior to the action being taken. You can link two watch groups using the OR action. When two watch groups are linked together with OR, the action will be taken if either groups are true. GOGO This action is used with Alarm Time. This action causes the system to move to the next segment if the watch item s value meets the criterion or the Alarm Time entered has elapsed. See Usage section of Watch Item on previous page for example. Watch Group parameters do not pass through to subsequent segments. For this reason, you will need to repeat the Watch Item is you wish to watch the same neighboring segments. 18

Pass-through: Value will NOT automatically pass to subsequent segments. Parameter description: Usage: This parameter enables an alarm that will sound when the watch group has been in a wait condition (GO and WAIT actions) too long. Use the time parameter in operations that may not be achievable. For example, if you are running an unsupervised load, you may want the system to sound an alarm if an operation requires more time than you anticipated.

56 CPC Operations Manual Recipe Parameters Page #4-22 Pressure Enable Units: ON or OFF. Applies to: Autoclaves, presses, and other equipment which utilize pressure. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter enables and disables pressure control during the recipe run. Pressure Enable must be ON in order for the equipment to pressurize or depressurize. Turning Pressure Enable OFF in the middle of a run will cause the pressurization valves to shut and pressure to remain at its current state. ON in Segment #1. OFF in the last segment. On most systems, if Pressure Setpoint is 0, the Pressure Enable operation will be over-ridden and the vessel will dump. 4-22

57 CPC Operations Manual Recipe Parameters Page #4-23 Heat Enable Units: ON or OFF. Applies to: Autoclaves, ovens, presses, and other equipment which utilize heat. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter enables and disables the heating system for the equipment. Heating Enable must be ON in order for the equipment to heat during the run. Once enabled, heating will be ultimately regulated by the action of the Temperature Control recipe group (ie. Control TC, Temp Rate, Temp Value, etc.) ON in Segment #1 or in the segment that you begin to heat. OFF in the last segment or in any segment when you don t need heat. Note: Be aware that if you disable heating in a cooling segment, the system will not be able to immediately correct an excessive cooling rate problem. Because of this, it may be useful to have Heat Enable ON in the cooling segment. 4-23

58 CPC Operations Manual Recipe Parameters Page #4-24 Cooling Enable Units: ON or OFF. Applies to: Autoclaves, ovens, presses, and other equipment which utilize heat and active cooling. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: This parameter enables and disables the coo ling system for the equipment. Cooling Enable must be ON in order for the equipment to cool during the run. Once enabled, cooling will be ultimately regulated by the action of the Temperature Control recipe group (ie. Control TC, Temp Rate, Temp Value, etc.) ON in Segment #1 or in the segment that you begin to heat. This is required so that the system can regulate the temperature properly. OFF in the last segment, except if you prefer to have the cooling remain ON after the run has ended. 4-24

Pass-through: Value will automatically pass to subsequent segments until changedor blanked (X). Parameter description: Usage: A non-zero entry for this parameter enables the Pressure Float function. The Pressure Float function is allows a natural drop in vessel pressure during a cooling process (adiabatic effects), during which the system will not attempt to maintain the current pressure setpoint. If pressure reaches the programmed Float limit, normal pressure control will take-over. This function is useful in reducing pressurization utility requirements and costs (i.e. Nitrogen usage.) Enter setting during cooling segments where the process specification allows a natural drop if pressure. Remember to blank the function in depressurization segments.

Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Parameter description: Usage: A non-zero entry for this parameter enables the Temperature Float function. The Temperature Float function allows a natural increase in vessel temperature during a pressurization process (adiabatic effects), during which the system will not attempt to cool the vessel to the current temperature setpoint. If the air temperature reaches the programmed Float limit, normal temperature control will take-over. This function is useful in reducing run time and cooling utility requirements and costs. Enter setting during pressurization segments where the process specification allows an uncontrolled temperature increase during pressurization. Remember to blank the function once pressurization is complete.

Pass-through: Value will automatically pass to subsequent segments until changed or blanked(x). Control action: Air temperature setpoint is limited to this temperature during an automatic cycle. Note: Depending on the configuration of the system, the control limit could be a lower temperature than the alarm temperature setting. This reduces nuisance alarms. Alarm action: Grace: The Max Air Temp alarm setting will cause the system to alarm if the air temperature exceeds the setting for the designated continuous Grace period. The Grace period is used to reduce nuisance alarms by causing the associated alarm condition to be active for a continuous period of time prior to sounding the alarm. The entry is in the time format xs or xm (i.e. 5M). Sensor(s) monitored: This alarm monitors the equipment s current controlling air temperature thermocouple. 4-28

77 CPC Operations Manual Recipe Parameters Page #4-43 Min Soak Temp Units: Minutes, or X for disabling the TimeInSoak function Applies to: Autoclave and oven applications which are required to utilize the advanced TimeInSoak function of CPC. Pass-through: Value will automatically pass to subsequent segments until changed or blanked (X). Description: This parameter is used only by companies that require TimeInSoak control. It is set to the minimum soak temperature for the specific cure process. Entry of this parameter automatically enables the TimeInSoak function and allows the recipe s progress to be controlled by the TIS (low time-in-soak) sensor value rather than by temperature. The TimeInSoak function utilizes the Low Soak Temp parameter to automatically determine the elapsed soak time for each thermocouple on each part during the run. This information is then used to calculate the minimum and maximum soak times for each part individually, and calculate a global minimum and maximum soak time for the entire batch. Once the global time is calculated a recipe can be programmed to use the Batch s Low Time-In-Soak value (LOTIS sensor) for cure progress rather than global HITC or LOTC temperatures. The advantage to using the LOTIS approach versus the temperature approach is that run times can be dramatically decreased in situations where operator or the system disables a low-reading thermocouple. In the LOTIS approach, the system will dynamically calculate a new total elapsed SoakTime after the thermocouple is disabled, possibly reducing the current elapsed soak time by minutes or hours. The disadvantage to using the TIS approach is that it results in a confusing and nonintuitive Recipe program. Additionally, because the soak period is dynamic, it is difficult to implement the Low Part Temp alarm. 4-43

79 CPC Operations Manual Batch Entry Operations Page # Batch Entry Operations The following chapter discusses the operations performed on the Batch Entry screen. This is the viewed batch, to be used for next run. This is the currently display part Heres where you enter part information. You can type a partnumber here to enter it directly. This image is automatically displayed from the database. This is a list of parts in the database. You can doubleclick an entry to add a new part. These are the sensors that are attached to the part. This is the area where database memos are displayed. You can dbl-click here to change the action for the vacuum lines. What is a batch? The term batch is used to identify a group of parts that will be processed together in a single run. This generic term is equivalent to the term Load on other systems. Why do I have to enter a batch? If the controlled application requires data and reporting on individual parts, you are required to enter the parts and part information on the batch entry screen prior to startingthe run. What s the difference between a PreBatch and CurrentBatch? The CPC system supports batching of parts for a current run (CurrentBatch folder) or batching of parts for future runs (PreBatches folder). Pre-batching is normally utilized only in high-volume production applications where parts can be identified and batched well before they are actually run. For most of your applications you will utilize the Batch selection in the CurrentBatch folder. 5-1

80 How to clear the old part information? CPC Operations Manual Batch Entry Operations Page #5-2 Upon entering the Batch Entry Screen, you will notice that the batch and parts from the previous run will still be entered. The following procedure should be used to clear the current batch contents. 1) Click the Remove From Batch button. 2) The system will display a message Remove all parts?. Click the Yes button. The currently selected Batch (top-left section) will remain, but the parts in the lower left section will be removed. Note: Don t click the Remove Batch button. This will remove the entire Batch object from the upper-left Batches section. What s the part database used for? The CPC Part Database stores common parts and part information that can be selected during part entry operations. The use of this database reduces typing errors and pr ovides the ability to track and record any number of part fields. Each part database record may contain field information (ie. Part#, Lot#, etc.), recipe matching information, tool information, and other fields used for quality control and post-run analysis of the part. How to edit the part database? Click the Edit Part Database button to access the Part Database Editing screen. See Database Management chapter for more information. How to add a part from the database listing? The following procedure can be used to create and enter a new part using the Part Database feature. 1) Scroll through the Part/Tool Database listing to locate the database selection. 2) Double-click the entry. The system will then add a new part based on that database entry. Upon adding a new part, the system will fill-in the part fields as designated in the Part Database. Automatic recipe selection If a Recipe field is identified in the database, the system will automatically load and select that recipe for the run. Once a recipe is selected, the system will insure that all subsequent parts match that recipe selection. If there is a recipe conflict the system will alert you with a message. How to add a part without using the database? The following procedure can be used to enter a new part without using the integrated part database. 1) Make sure the last part in the lower-left section is highlighted. This will position the new part at the end of the list. 2) Click the Add To Batch button. A new part will be added. 5-2

After the wand operation, the system will highlight the next part entry field so that it can be wanded or typed. How to add multiple parts under one bag? A useful feature of the CPC batch entry system is the ability to add multiple parts which use use the same set of attachment sensors (ie. vacuum probe). This type of entry is often referred to as a multibag or multi-part tool. The following procedure shows how to create a multi-part tool/bag entry: 1) Make sure that the As a Single Part checkbox is selected. 2) Add the first part. 3) Select the sensor attachments for the multi-part bag. The first part will now be the container or parent-part for the other parts in the set. 4) Now click the As a Part-on-Tool checkbox to indicate that subsequent part additions will be added as a set to the first part. 5) Add the next part. The system will create this part as an indented child of the first part (lower-left display). It will also automatically inherit the sensors from the first part. 6) Repeat step #5 for the remaining parts in the multi-part set. Upon adding the final part in the set, click the As a Single Part checkbox to continue adding normal parts. Entering part fields If you are using the database feature to enter the parts, the system will automatically fill in some of the required part fields. You can enter the other fields by clicking the field entry and typing a new value. If configured, the fields can also be setup to displa y a pull-down listing of entry options. You can access the pull-down listing by double-clicking the entry. What are part attachments? Part attachments are thermocouples, vacuum probe transducers, vacuum source lines, and other items that are phyically connected to a part or tool in order to record and/or display the temperature and/or vacuum level of the part during the run. In order for the software to correctly record, control, and alarm each part, the attachments for each part must be selected on the batch screen. 5-3

82 How to select part attachments CPC Operations Manual Batch Entry Operations After you ve entered the part field information for the current part, you can select the attachments by following this procedure Page #5-4 1) Click the Select Attachments button. The system will display the attachments selector. 2) Click the appropriate tab and select the index number of the sensor(s) and lines that are physically attached to the actual part. Indication that attachment has been used Once a sensor is selected, its index number will be eliminated from the grid display on subsequent part entrys. This eliminates the possibility of duplicate sensor attachment in a given batch. Indication that attachment is decertified Sensors which have been decertified (calibration) or set to faulty (operator) will be displayed in red. Red indexed attachments cannot be selected for a part. 5-4

83 Which attachments have actions? CPC Operations Manual Batch Entry Operations Page #5-5 There are a few types of attachments which include paired actions which are used to control the phyical state of the attachment hardware. These attachments will force the attachments selector for to display the possible action choices during attachment operations. Vacuum source lines with valve selection On some autoclaves and ovens, the vacuum source lines have automatic valving which can be set for VAC, VENT, or OFF action. Vacuum probe lines with SRC or PRB selection Some autoclaves have dual purpose vacuum lines which can be selected for source operation or probe operation. In this case, the vacuum line would be the attachment and the action SRC or PRB would be displayed (see figure above) Changing the action of the attachment You can change the attachment action two ways: 1) Click the action button on the selection form during the attachment operation. Or.. 2) Double-click the action verb on the part sensor display portion (bottom-right of batch entry screen).

Note: You will require at least Operator security access in order to enter this screen. Datafile and run-database information The data-analysis screen provides access to view individual file contents (i.e. run data) as well as database information. Datafile The CPC system stores all run information (i.e. part information, sensors, run data, messages, etc.) in individual datafiles (DAT extension). A new datafile is created for each run processed. These datafiles are the source of the information displayed and reported in the dataanalysis screen. Datafiles are normally stored in the C:\Data directory on the primary and backup PC s harddrives. Additionally, if your system is connected to a remote server, the datafiles will be archived to a server drive for remote viewing and storage. Run Database The CPC run database is a single relational database that contains specific information from each and every run. This information includes part, attachment, run, recipe, process, and QA status records. The run database is useful for searching and locating specific run data by utilizing fielded search criteria. The run database is also the source of SPC reporting via the SPC system.

101 7. Part-Tool Database Management CPC Operations Manual Part-Tool Database Management This chapter describes the following database management topics: Part-Tool database Creating the database tables Editing databases, including adding and deleting new records Database implementation What is the part-tool database? Page #7-1 The Part-Tool database contains information on the production parts and production tools that will be processed in the equipment. Though the use of the database is optional, it can be a useful tool in production environments. Why should I use the part-tool database? The part-tool database is a useful production tool that provides the following benefits: Ease part entry The part-tool database can be utilized to speed-up part entry. During part entry operations, the operator can select a part from the database. At this time the system will automatically enter all relevant constant fields (e.g. part #, name, description, material, etc.). Eliminate errors When used during part entry, the database feature will eliminate typos and other entry errors. This is critical in production systems that utilize CPC s SPC and post-run analysis features. Automatic Recipe selection If you utilize the part-tool database during part entry, the system can be configured to automatically load the correct recipe for the part(s) that are entered. Additionally, any part/recipe incompatibility will be identified to the operator at entry time. Tool cycle management If you utilize the tool feature of the database, then the system will automatically track each tool s cycle count, and warn the operator when the tool is due for maintenance. What is a part template? A part template is a pre-defined limited list of part database fields that will be displayed to the operator during Batch entry operations. Typically only fields that require operator entry are displayed in the template. Renaming fields The template allows you to rename the database source fields for operator viewing. For example, if the database field is PARTSN, you can create a part template field named Part Serial # that references the database field. 7-1

102 Memos CPC Operations Manual Part-Tool Database Management Page #7-2 The part template field can be assigned as a memo. In this way the information stored in the targeted database field will be displayed in the memo section of the Batch entry screen. Pictures The part template field can be assigned as a picture. In this way the information in the targeted database field will represent a picture file (e.g. PART.JPG) and will be displayed in the picture section of the Batch entry screen. Database structure The Part-Tool database includes two tables, each of which have a required minimum number of fields. Parts table The following minimum required fields are included in the Parts table. Note: you can add any other field as required by your process. RECORDID PARTTEMPLATE Automatically generated record identification number. Note: This is not shown on the Edit Parts Table screen. Identifies the template that will be used for editing this part in the Batch entry screen. Note: TEMPLATENAME can also be used. RECIPE This identifies the recipe file (e.g. Recipes\Epoxy) that will be automatically selected whenever this part is entered. The following fields are only included on systems that will utilize the tool feature of the CPC system. TOOL TOOLLIST Tools table This identifies which tool is used for this part. The name of this field can be different (e.g. TOOLSN) depending on the installation. Note: This tool field is a link between the part record and the tool record in the tool table. This field represents a comma-delimited listing of tools that can be used with this part. The following required fields are included in the Tools table. Note: This table is only utilized on installations that use the tool tracking feature of CPC. RECORDID TOOL Automatically generated record identification number. Note: This is not shown on the Edit Tools Table screen. This is the serial number of unique identifier for the tool. The name of this field can be different (e.g. TOOLSN) depending on the installation. 7-2

Calibration and Certification This chapter provides information concerning calibration and certification of sensors used on the CPC system. Note: Each CPC installation is highly customized to meet the equipment and customer requirements. Due to this per-system customization, the information, examples, and screens described in this chapter may differ from your exact installation. Definitions The following definitions are offered: Calibration Calibration refers to the act of modifying the software constants used by the system to adjust the accuracy of a sensor s value. Calibration is normally required whenever a sensor value is inaccurate when compared to a certified standard. Certification Certification refers to the procedure that validates and records the accuracy of a sensor or group of sensors. The certification process typically creates a Certification Report. Security requirements In most installations the calibration and certification screens are locked for all users except maintenance and cal/cert personnel. Prior to accessing the calibration and certification screens, you will need to log into the system using an appropriate user. Accessing the calibration and certification screens From the Main Screen, click the Support button to access the Support Screen.

How to interrupt the certification process You can interrupt the certification process and close the certification screen at any time. When you close the screen the system will ask whether you want to continue the current certification later. If you answer YES, the system will save the current certification results so that you can restart the process without having to re-certify the currently certified sensors. How to recertify a sensor It is often desirable to recalibrate a sensor after it certifies in order to improve its accuracy. After re-calibration you can use the Reset Sensor button to FAIL that sensor so that recertification can be performed. 8-10

121 When to use variable-reference certification CPC Operations Manual Calibration and Certification Page #8-11 The following section discusses the use of variable references in the certification of vacuum systems. This option is seldom used and is normally pre-configured in the vacuum certification screen. Fixed-reference defined A fixed reference certification uses constant values (i.e. 100,250,350) as the standard references for comparing and certifying the monitored temperature values. Variable-reference defined A variable reference certification uses an accurate sensor (individually certified) as the standard used for certifying a group of similar sensors. Vacuum certification with variable-reference In a variable-referenced certification process the system automatically controls the variable referenced sensor (i.e. SYSVAC) at consecutive setpoint levels. At the end of each setpoint stage the system performs a single scan of all sensors for that certification level. At the completion of all stages the system automatically deselects the Auto Cert Enable switch. 8-11

124 How CPC security works CPC Operations Manual Security Management The CPC security system is a flexible system that can be configured and applied to all aspects of CPC software operations. Security Sentry Page #9-2 When your specific CPC software configuration was created (i.e. at commissioning of system), an ASC field engineer added individual Security Sentry objects to all operations that required security access. Note: Only operations that have a Security Sentry applied are secured. Each Security Sentry confirms that the currently logged-in User has the required Group membership(s) prior to allowing the selected operation. A security sentry can be configured to be Permissive (only specific Groups have access) or Restrictive (all Groups except sepecific ones have access). What operations are secured? The following is a partial list of operations that are normally secured in a CPC installation. Screen Access Recipe editing Run operations (e.g. Start Run) Security management Database management (e.g. Part Database) System configuration via Object Editor Manual override controls Any operation on the CPC system can be secured with a sentry object. If you require additional security sentries, contact ASC for assistance. User defined A User is an individual person or organization of people that will use the CPC software. Each User is added to the Security system and will include a Name, Password, and a configured list of security Group memberships that are applicable. As an individual person You can setup the security system with individual Users for each person using the system. This is typical of production operations that require tracking of specific operators and personell on the system. As an organization of people You can setup the security system with minimum Users that represent the type of person that will be using the system. For example, rather than have a one-to-one relationship between a security User and a real person, you can instead have a group of people use a single log-in User (e.g. LabOperator). 9-2

125 Group defined CPC Operations Manual Security Management Page #9-3 A Group is a specific membership that can be applied to a User. Each User can have a single membership or a number of memberships. Because each Security Sentry contains a list of Groups that are either permitted or restricted from the specific operation, Groups are typically pre-configured during system commissioning. Typical Groups Operator Usually applied as a low-level security access. Engineer Usually applied to users that require Recipe editing, support, and database managmenent access. Calibration Usually applied to users that must calibrate the system. Maintenance Usually applied to users that are given the ability to force I/O and view scripting. Supervisor Usually applied to users that are given access to the security management system. Multiple groups for one user Because security sentries utilize the Group, and not the User, as the validation for the operation, it is normal to apply more than one group to each user. For example, if you want a user to be given access to setup and start a run as well as program new recipes, that user would probably be given both the Operator group and the Engineer group. Adding a new User 1.) Click the Add User button. A New User will be created. 2.) Change the Name, Description, Department, and Password of the User. Note: Password2 is not used at this time. 3.) Add a group or groups to the user. Adding groups to a user This procedure can be used to add new memberships to a specific user. 1.) Select and click a user name in the Users listing. The screen will show the user s currently group memberships in the Selected Groups listing. 2.) In the All Groups listing, double-click the membership(s) that you want applied to the user. As you make the selection, the Selected Groups listing will be updated. Note: You can also click the group and then click the button to add the group. Removing groups from a user This procedure can be used to add new memberships to a specific user. 1.) Select and click a user name in the Users listing. The screen will show the user s currently group memberships in the Selected Groups listing. 2.) In the Selected Groups listing, double-click the membership(s) that you want removed. As you make the selection, the Selected Groups listing will be updated. Note: You can also click the group and then click the button to remove the group 9-3

126 Adding a new group CPC Operations Manual Security Management Page #9-4 The following procedure is used to add a new security Group. This is often required if you want to add or modify security sentries in order to target a specific type of user. 1.) Click the Add Group button. A New Group will be added at the bottom of the All Groups listing. 2.) Click the Rename Group button and then type the new group name, followed by the <enter> key. 9-4

127 CPC Operations Manual Script Maintenance Page # Script Maintenance This chapter describes the following Scripting topics: What is a script? How to access and view Scripts How to read a Script Script debugging I/O Forcing Note: This chapter describes the information useful for script viewing and/or maintenance purposes. This is not a chapter on script programming. What is a script? A CPC Script is a logic program that performs a sequence of operations on CPC variables and physical equipment I/O. Script usage Many Scripts are used throughout the CPC configuration to perform many tasks: PLC Logic Scripting is often used for standard PLC-type logic. Event operations Scripting is used to perform custom operations at specified events. For example, a custom script is run at the commencement of each automatic run. Scripting language The CPC Scripting language was created by ASC to provide an easy way of programming control logic and operational sequences. The design of the scripting language and the script editor is patterned after Microsoft s VisualBasic product. Note: Though CPC Scripting appears very similar to VisualBasic, it is not compatible in any way to this product. Scripts types There are two types of scripts used on the CPC system. One type is based on a script object, and the other is a quick-script that is always run when a specific event occurs. Script objects Script objects are fixed objects that contain not only the un-compiled text version of the script, but the compiled version of the script. Compiled scripts run much faster than the un-compiled form. Quick-scripts Quick-scripts are actually properties of other objects (e.g. RecipeProcessor), and are run only when events within those objects are activated. Quick-scripts represent only the text information of the script, and therefore are un-compiled at the time of running. 10-1

128 CPC Operations Manual Script Maintenance Page #10-2 Viewing the scripts Each CPC software installation includes dozens of custom scripts that have been created and/or modified to meet the specific demands of the equipment or control application. Depending on the configuration of the system, you can access and view the scripts in one of the following ways. Support screen access On some larger installations, the Support Screen includes buttons that access the Script Editor for each of the larger fixed Script objects. When you click the button, the CPC Script Editor will be displayed. Accessing Script objects in the Object Editor You can also access fixed Script objects by locating the script objects using the Object Editor. To access the Object Editor, right-click at the top of the Main Operations screen and select Object Editor from the pull-down menu. You ll need Engineer, Maintenance, or Supervisor group access. Properties (white) and methods (yellow) of the selected script object. Selected Script object Double-click here to view/edit the script. As you see by this example, the fixed Script objects (as a child of the Scripts object) can be viewed and/or edited by double-clicking on the Edit method. This will display the CPC Script Editor. 10-2

129 CPC Operations Manual Script Maintenance Page #10-3 Accessing a Quick-script in the Object Editor You can use the Object Editor to access and view the quick-script property on any selected object. Note: Quick-script properties are displayed as green. BeforeStartRun quickscript for this object. Double-click to view/edit. AfterEndRun quick-script. Selected object (RecipeProcessor) AfterSegment Change quick-script. A number of standard CPC objects contain one or more quick-script properties. To view and/or edit the quick-script, you must double-click on the specific quick-script text. 10-3

130 CPC Operations Manual Script Maintenance Page #10-4 Using the Script Editor The CPC Script Editor is used to view, edit, or debug the selected script or quick-script. Show the Forcing window. Name of script Show the Debug window Aliasing section Script comment Scripting statements (logic) Editor security The Viewing and Editing of the editor can be separately secured. In most cases the Maintenance group is given View access and Engineer/Supervisor groups are given full access. Script Name The Sub.. at the top of the script defines the name of the script. You cannot change the script name from inside the editor. Script objects can be renamed from the Object Editor (Name property). Quick-scripts are automatically named according to the parent object s name and the quick-script property name. For example, an AfterEndRun quick script in the RecipeProcessor object will be names RecipeProcessor_AfterEndRun. 10-4

131 Aliasing CPC Operations Manual Script Maintenance The top portion of each script is generally used for defining the Alias variables used throughout the script. Page #10-5 An Alias defines a text substitution where a word can be utilized in place of a long string of text. Aliasing is often used in order to consolidate CPC object and property paths. For example, the PinLock alias in the script on the previous page is used to substitute for.autoclave.inputs.pinlock\value. Note: Aliasing has local scope, and is therefore only applicable to the script where it is defined. Global aliasing is not supported at this time. Understanding objects and property paths Scripting is primarily used to manipulate and modify CPC objects and their properties, and in order to identify the property in scripting, a path methodology was incorporated. The following information is provided: A Period. is used to identify a parent/child object relationship. A back-slash \ is used to identify a object/property relationship. The following example is offered: According to the Object Editor view above, you can see that there exists the following object relationship: Autoclave is parent of Outputs is parent of EXHAUSTIP The EXHAUSTIP object is of an Output_Direct classification (see Cls: at bottom left of window). The following example describes how you would alias the Value property of this object: Alias ExhaustIP =.Autoclave.Outputs.EXHAUSTIP\Value 10-5

132 CPC Operations Manual Script Maintenance The following example shows how you would use that alias in logic: If ExhaustIP > 75 Then ExhaustIP = 75 EndIf Page #10-6 The following example describes how you would use the non-aliased version in logic: If.Autoclave.Outputs.EXHAUSTIP\Value > 75 Then.Autoclave.Outputs.EXHAUSTIP\Value = 75 EndIf Comments Scripting comments are descriptive text entries that are used to document the scripting. Comments are displayed as green text and are always preceded by an apostrophe ( ). If-Then grouping If you are not familiar with Basic or VisualBasic programming, the If-Then statements which are used extensively in scripting may require some explanation. The If-Then grouping statement is used to perform statements only if a conditional statement is true (or untrue). The following example is offered: If AirTemp > 300 Then AirCool = On MistCool = Off ElseIf AirTemp > 150 Then AirCool = On MistCool = On Else AirCool = Off MistCool = Off EndIf This statement provides the following functionality: AirCool will be ON and MistCool will be OFF whenever AirTemp is greater than 300. AirCool and MistCool will be ON if Airtemp is greater than 150 but lower than 300. AirCool and MistCool will be OFF if AirTemp is less than 150. As you can see, the flow of the statement is such that the if the first condition is untrue, then the next condition will be tested. If that condition is untrue, then the next condition will be tested. If no conditions are true, then the Else statement will test true and the script statements between the Else and the EndIf will be carried out. An If-Then statement only requires the beginning If and Then as well as the ending EndIf. 10-6

133 For-Next statements CPC Operations Manual Script Maintenance Page #10-7 The For-Next statement is used in order to perform and sequence loop. The following example is offered: Dim ThisInput Dim ThisValue Dim ThisCount For ThisCount = 1 to ChildCount(.Autoclave.Inputs) ThisInput = GetChild(.Autoclave.Inputs,ThisCount) ThisValue = GetProperty(ThisInput, Value ) If ThisValue > 200 Then other statements EndIf Next ThisCount This short scripting example performs the following function. The variable ThisCount is sequenced from 1 to 2 to 3 to the maximum number of children objects under the Inputs object. During each sequence pass the variable ThisInput is set to a specific child Input object that is targeted by the ThisCount index number (GetChild function). The variable ThisValue is set to the Value property of the ThisInput object. ThisValue is then compared to 200 in order to proceed to other statements. The Next keyword serves to continue the For sequence until ThisCount is equal to the result of the ChildCount function. 10-7

134 Using the Debug window CPC Operations Manual Script Maintenance The Debug window is used to view the actual real-time values of all of the variables and object/properties used in the script. Page #10-8 You can view the Debug window by clicking the Debug icon at the tope of the Script Editor screen. Locating script usage Click on the variable in the Debug window and all uses of that variable will be underlined in the Script Editor. Locating debug variables When the Debug window is displayed, you can double-click on the variables, aliases, and object properties in the script to automatically locate the entry in the debug window. Once you ve selected the script variable, the system will highlight the specific row in the debug window. Debug not used for forcing The Debug window cannot be used to force a variable to a specific value. 10-8

135 CPC Operations Manual Script Maintenance Page #10-9 How to Force inputs and outputs This section describes how to force Inputs and Outputs to a specific value using the Force I/O window. Warning: Forcing inputs and outputs will override normal functionality and interlocks, possibly causing a danger to equipment and personnel. Do NOT force any output or input that may jeapordize the safety of the system. Forcing defined Forcing refers to the method used to manually set an input or output to a specific value. This Force will override normal operation of the item, and will also override any logic interlocks that are built into the system. See warning above. When to use Forcing Forcing is usually performed by maintenance personnel in order to test a valve or component on the equipment. For example, if a cooling valve is malfunctioning, a maintenance user may wish to force that output ON and OFF in order to test the valve. The Forcing window You can access the Forcing window by clicking the Forcing icon at the top of the Script Editor screen. Step2: Select the value by clicking On/Off or by entering a new value. Step3: Click Set Step4: The force will be applied. Step1: Click the item you want to force 10-9
