7 Chapter 1 System Startup 7 Central Station Hardware/Software The SCADA System needs the following Central Station hardware and software: 1) RACO SCADA System Software 2) MS-DOS 5.0 Disk Operation System (DOS) 3) Surge Protector Power Strip 4) Telephone Line - Data Grade Recommended 5) 120 VAC Power 6) Uninterruptible Power Supply (UPS) (strongly recommended) For systems with up to 16 RTUs 100% IBM Compatible PC 20Mhz 80386DX CPU 640K RAM 80 MB Hard Disk 5.25" 1.2 MB (or 3.5" 1.44 MB) Floppy Drive VGA Display Adaptor/Monitor Hayes Compatible 1200/2400 baud Modem Panasonic KX-P1180 Printer For Systems with 17 or more RTUs 100% IBM Compatible PC 33Mhz 80386DX CPU 640K RAM 140MB Hard Disk 5.25" 1.2 MB (or 3.5" 1.44 MB) Floppy Drive VGA Display Adaptor/Monitor Hayes Compatible 1200/2400 baud Modem Panasonic KX-P1180 Printer RTU Hardware Any model Verbatim may be used as an RTU but it must have the RACO Asynchronous Communications Option installed before it can be accessed by the Central Station. For Installation of the Verbatim RTU refer to your Verbatim Owner's Manual.

8 8 Chapter 1 System Startup Central Station Configuration Computer Startup If your Central Station computer was configured by RACO, your software and DOS should already be loaded. If you are starting your computer for the first time, refer to the installation guide which comes with your computer and to the DOS manual for configuration and startup of your computer. Note: You should be advised that RACO does not recommend that the SCADA system be run under the Windows 3.xx operating system. The system specification calls for the SCADA system to run under DOS 3.x or greater as the sole program. If you have any questions regarding SCADA program compatibility issues, please call RACO Technical Support. Printer Startup Refer to your printer manual for correct configuration and startup of your printer. Make sure your printer is connected to printer port #1 (LPT1). Modem Startup If your modem is configured via internal DIP switches, they should be configured to reflect the following feature settings: Feature DTR Status Result Code Format Result Code Display Character Echo Auto-answer Carrier Detect Telco jack type Command Recognition Comm standard 1200 bps Response to DTR transition Set to Follows DTR; goes to command state if signal drops. Verbal Displayed Characters echoed in command state. Disabled Reflects actual result of attempt to connect. RJ-11 Enabled Bell 212A Hangs up and goes to command state.

9 Chapter 1 System Startup 9 Data Compression Off Error Checking Off Read Me File Before attempting to install or to upgrade your existing RACO SCADA System be sure to read the READ.ME file on the distribution diskette. The READ.ME file may include important information relevant to the configuration of your system. To read the READ.ME file insert the distribution diskette into the A drive. Then type "more< read.me". Press the spacebar to read more of the READ.ME file. To stop reading the READ.ME file you may type [CTRL-C]. This file may also be viewed by any editor or word processor program which may read a standard DOS text file. Installing the SCADA Software Put the distribution diskette into the computer A drive. Type "A:" Type "install" You will be asked to answer several questions about where you want the software to reside on your hard drive and about configuring the system for automatic start-up. System Memory Requirement The RACO SCADA system requires a minimum of 540K free RAM to run. You may accommodate this by the following methods: - If you have extended memory, you may load DOS in high RAM, thereby freeing up more of your 640K RAM for applications. - You should not be running any other applications while the SCADA system is running. This is to avoid potential conflicts which might impair your alarm monitoring and data collection. Running the SCADA Software

10 10 Chapter 1 System Startup If your system is not set to automatically start-up when you turn on your computer, do the following from the DOS command line: Type c: (If you chose to install on the D drive type d:) Type cd \raco Type raco The first time you start the RACO SCADA System you will be asked several questions about the configuration of your system and your RTUs. You will be asked about the number and types of channels in each RTU in your system. Refer to your system engineering specifications for this information. Quick Start If you want to start the system without reading the entire user manual you may do so comfortably knowing that there is a sophisticated HELP system which is on-line, all the time. Just read the applicable manual section on the use of the function keys ([F1] and [F2]).

11 Chapter 1 System Startup 11 Major Topics in this User Manual Key Usage - The specific functions of certain keys Using a Mouse - If you have a mouse installed The Screen - What the major sections of the screen tell you System Options - What the System Options are Polling - Automatic or Manual; when and how often it happens Reports - How to generate reports about the System or RTUs Programming - Setting up programmable features of the RTU Alarms - How they appear and how to handle them System Environment - Configuring your modem and directories. Data Archiving - Database storage and retrieval. Data Conversion - Exporting to database and spreadsheet. Message Log - Tracking system events. Utility Program - Changing your RTU network configuration

12 12 Chapter 2 Keyboard, Mouse and Screen The Action Keys ENTER Use the [ENTER] key to make a selection from a menu of choices. For instance, when the program is first started, except for the status and time windows, only the topmost menu bar will show with no pull-down menus visible. Press [ENTER] to cause a menu to "pull-down" for whichever selection is highlighted on the menu bar. Press [ENTER] again to select the first choice in the menu and a window will open for the selected choice. CONTROL-ENTER This is a two key combination. To Press [CTRL-ENTER] hold down the [CTRL] key and hit the [ENTER] key. Press [CTRL-ENTER] when you have finished making entries or editing all the fields in a window. This two key combination is used to emphasize the fact that your entries will only be recorded at this time. If you press [ESC] to exit a window without having pressed [CTRL-ENTER] then your changes will be discarded. ESCAPE Use the [ESC] key to undo a selection, discard changes, or to exit a window and return to the previous window. From within a window press [ESC] to exit and close the window. Pressing [ESC] within a pull-down menu will cause the menu to vanish leaving only the main menu with one choice highlighted. Cursor Control Keys You may use the cursor control keys to move around within a window or menu. Use the arrow keys to move among the fields within a menu. In some cases a field may be "editable". In an editable field, such as in phone number entry fields, the right and left arrow keys are used only to move within the field. Using these keys it is possible to edit the characters and make corrections within the field. When a function is activated and it's window is opened there may be more information within the function than is visible through the window. For instance, if your system has more than ten RTUs the "Select RTU" window will only show ten RTUs at one time. Any such window (of which there are many) is called a "scrollable window". In scrollable windows you will see a shaded fine checkered vertical bar just inside the rightmost border of the window. This is called a "scroll bar" and is shown in all "scrollable" windows. You may use the [PGDN]

13 Chapter 2 Keyboard, Mouse and Screen 13 and [PGUP] keys to scroll through the window and reveal the rest of the information. You will see the heavily shaded portion of the scroll bar move up and down the scroll bar as you move the window up and down. This gives you a guide to the approximate position of the window within the scrollable information. In certain windows there are "editable" fields. For example, RTU Naming uses editable fields for entry of the RTU Names, Channel Names, etc. You might wish to make changes to such an editable field. Use the [HOME] key to move to the leftmost character in the field. Use the [END] key to move to the rightmost character in field. Main Function Keys Some specific functions within the RACO SCADA System have been assigned to Function keys. [F1] is the help key and is always available at any point in the program. [F1] provides access to the general help system and gives information on the basic operation of the program. You will benefit from the "general" help information when you are becoming familiar with using the program. Or, you may also refer to it if you forget how something works. The general help system is accessed through a set of cross-indexed menus. Make menu selections to go from the most general to the most specific item of interest. [F2] is the item help key and is also always available at any point in the program. [F2] gives item specific help and is context sensitive. [F2] will most always provide help on the item which is currently highlighted. This means, for instance, that you could be deep into the programming of contact alarm criteria, press [F2] and get a specific help message explaining the programming of this feature. There is item help available at almost every point in the operation of the program. [F9] is used to enter the Status Window. Editing Keys In certain windows there are "editable" fields. For example, RTU Naming uses editable fields for entry of the RTU Names, Channel Names, etc. You might wish to make changes to such an editable field. Use the right and left arrow keys to move within the field. Use the [DEL] key to delete the character at the cursor position. Use the [BACKSPACE] (or <-) key to delete the character

14 14 Chapter 2 Keyboard, Mouse and Screen to the left of the cursor. Use the [INSERT] key to toggle between "insert" and "overwrite" modes. When in insert mode the cursor is an underline. When in overwrite mode the cursor is rectangular. Insert mode inserts typed characters at the cursor shoving the characters to the right of the cursor further to the right. Overwrite mode replaces characters with the typed character. In some fields you must choose between just two options such YES or NO. In other fields the two choices might be ON or OFF. You may use the [SPACEBAR] to toggle the choice between the two opposites. Using a Mouse If you have a compatible mouse installed on your central station computer you may use the mouse to do many of the same functions as may be performed with the cursor control keys and the [ENTER] key. In most cases the left mouse button will work the same as the [ENTER] key. Use the mouse to make menu choice selections. To select a choice from a menu simply move the mouse cursor until it's on top of the desired choice and then press and release the left mouse button. However, in some cases you will need to click the mouse on either the [CTRL-ENTER] or [ENTER] label on the Prompt Line at the bottom of your screen. Also, if you are in a window which is displaying a scroll bar you may use the mouse to scroll the window up or down. To scroll using the mouse move the mouse cursor to one of the arrows at the top or bottom of the scroll bar. Press the left mouse button to "click" on the arrow. The window will be continuously scrolled as long as the left mouse button is held down.

15 Chapter 2 Keyboard, Mouse and Screen 15 The Main Screen When the RACO SCADA System is first started you will see on the screen from top to bottom: The Main Menu Line The Status Display Window The Time Window The Prompt Line At other times there will be various pull-down menus and windows on the screen.

16 16 Chapter 2 Keyboard, Mouse and Screen The Main Menu Line The main menu line at the very top of the screen allows the selection of a major function. The major functions are: System Polling Report Programming Control Tools Quit The Status Display Window The Status Window allows the SCADA System to send data to the screen. During polling calls or during an incoming alarm, the status of the poll or alarms calls will be sent to this window. Use [F9] to open this window and examine it's contents by using the arrow keys and page keys. Incoming data which is sent to this window is also stored in the database so data which has scrolled away out of the window is never lost. The Status Window always holds the most recent status information. The window makes use of a "buffer" which is analogous to a tank with the inlet at the bottom. The oldest data is forced to overflow the tank and exit when new data is forced in the inlet. The oldest data is automatically replaced by the next oldest data when new data enters the inlet. The age of the data in the status window depends not only on the size of the buffer but also on the size and frequency of data being sent into the window. The Time Window The Time Window shows three items. The first item shows the current time. The current time is the time of day as known to your Central Station computer. You may change the time and date if it's not correct from within the RACO SCADA System (explained later). The second item shows the time to the next poll which is the actual hours, minutes and seconds until the next poll will occur. The third item shows the actual time of day when the next poll will occur. Note that the current time and the time of the next poll are in military time format. The Prompt Line The prompt line at the very bottom of the screen is used to give a short description of the most relevant key press choices. The information on this line is context sensitive and will change according to your current location in the program. For example, when the

17 Chapter 2 Keyboard, Mouse and Screen 17 program is first started the prompt line will show that you may use following keys: F1:Help F2:Item Help F9:View Status But, when you are in the window for entering the RTU phone numbers the prompt line will show: Ctrl-Enter:Save Changes Esc:Discard Changes Note that the prompt line says nothing about the implicit key choices. The implicit keys are the keys which are almost always active in all windows and functions such as the arrow keys.

18 18 Chapter 3 Running the SCADA System System Menu Options Operations performed under the System Menu: Alarm Acknowledgment RTU Telephone Numbers Central Station Number RTU Naming Time of Day Installation Test Password Version Information

19 Chapter 3 Running the SCADA System 19 Alarm Acknowledgement Modes There are 3 different ways the Central Station can respond to an alarm from an RTU: Operator Acknowledgment No Acknowledgment Automatic Acknowledgment

20 20 Chapter 3 Running the SCADA System Operator Acknowledgement When an alarm call is received from an RTU the program will print a message about the alarm on the screen and create an audible alarm signal. The operator will be asked to decide whether to acknowledge the alarm by pressing 'Y' or 'N' on the keyboard. If the operator does not acknowledge the alarm, the RTU will make voice calls to personnel for acknowledgment. All alarms will be logged to the local printer and to the hard drive at the Central Station. Automatic Acknowledgement When an alarm call is received from an RTU the program will print a message about the alarm on the screen. The alarm will be acknowledged by the Central Station with no action required by either the operator or other personnel. All alarms will be logged to the local printer and to the hard drive at the Central Station. However, no audible signal will sound at the Central Station. No Acknowledgement When an alarm call is received from an RTU the program will print a message about the alarm on the screen. The program will not acknowledge the alarm call and the RTU will automatically go on to make voice calls to personnel. All alarms will be logged to the local printer and archived to the hard disk at the Central Station. However, no audible signal will sound at the Central Station.

21 Chapter 3 Running the SCADA System 21 RTU Phone Number List The RTU Phone Number List is the list of phone numbers to which each RTU is connected. Enter the telephone number for each Remote Terminal Unit (RTU). If you need a delay during dialout to accommodate your telephone system, insert a comma (",") at the appropriate place for each second of delay required. The Baud Rate is the speed at which information is exchanged between the Central Station and the RTU. Most installations will operate properly at the default Baud Rate of 1200 baud. If your telephone lines are particularly noisy, or if you are having trouble getting through to one or more RTUs, use the [SPACEBAR] to set the baud rate to 300. To deactivate a RTU, delete its phone number. This will prevent the RTU from being included in Polling or Installation Tests. To reactivate the RTU, simply re-enter the phone number.

22 22 Chapter 3 Running the SCADA System Central Station Number The Central Station Number is the number of the phone line to which the Central Station modem is connected. It's the number that an RTU must call when it makes an alarm call to the Central Station. NOTE: The Central Station phone number must be entered prior to performing any Installation tests.

23 Chapter 3 Running the SCADA System 23 RTU Naming For clarity in the reports and printouts produced by the Central Station, you can enter a name for each RTU and each channel of each RTU. You can also enter alarm and normal messages that will be printed both on the screen and on the printer as a part of each status report and alarm. From the RTU Naming menu select from the list of RTUs. Your first choice will be to name the RTU. Next, for each channel enter a Channel Name, an Alarm Message Suffix and a Normal Message Suffix. Also, for analog input channels or contact input channels configured as totalizers, you may enter Engineering Units. This Units string will be appended to the analog or totalizer reading value when shown on the screen or in reports. For example, you might use a channel name of "Water Tank Level" and units of "feet". Then that channel's reading would come out as something like "Water Tank Level 32.5 feet".

24 24 Chapter 3 Running the SCADA System RTU Name The RTU Name you assign should describe the location of the RTU and/or the equipment which the RTU is monitoring such as "Chico Well #5" or "Brighton Township Pump Station". Channel Name, Alarm and Normal Suffix Messages Name each channel in the RTU: The channel name should describe the sensor connected to that channel or should describe machinery being monitored by that channel. For instance, "Pump #2 Run-time" or "Intrusion" or "Wet Well". Channel Suffixes: Either the Alarm or the Normal Suffix Message will be appended to the channel name (except for contact channels set for run-time). So, if your channel name was "Water Tank" then you might enter Alarm and Normal Suffixes of "Low" and "Normal", respectively. Engineering Units: For analog input channels or contact input channels configured as totalizers you may enter Engineering Units. This Units string will be appended to the analog or totalizer reading value when shown on the screen or in reports. For example, you might use a channel name of "Water Tank Level" and units of "feet". Then that channel's reading would come out as "Water Tank Level 32.5 feet". Deactivating a RTU To temporarily remove an RTU from polling, as in the case of site maintenance, you can simply remove its phone number. This will prevent its being included in the Scheduled Polling of all RTUs. In addition, the polling report will indicate that there is no phone number listed for any RTU temporarily deactivated to indicate to the systemoperator that an RTU is not being polled.

25 Chapter 3 Running the SCADA System 25 Time of Day The RACO Central Station allows you to set the time of day and the date without exiting to DOS. After selecting Time of Day from the System menu, simply enter the current time and date (use the cursor keys to move between the two). Press CTRL-ENTER to save the new time and date. Press [ESC] to exit without changing anything. If you enter an incorrect time or date (13/32/90 for a date, for example) the RACO Central Station software will not allow you to save the number. You must either press [ESC] or [BACKSPACE] to the incorrect number and re-enter the time or date.

26 26 Chapter 3 Running the SCADA System Installation Test The Installation Test is a procedure used principally during system start-up to test and initially program each RTU in the system. The Central Station calls each RTU to verify correct operation. and inserts it's telephone number into the programming of the RTU. Also, the Central Station gives each RTU a unique identification that is sent back by the RTU whenever the RTU calls. Then the RTU will automatically place a call back to the Central Station thereby verifying the RTU's ability to make calls to the Central Station in the event of an alarm. It is very important that the person who installs the RACO SCADA System do an Installation Test from the Central Station for each RTU in the System. It is also critical that the Central Station Number be filled in prior to performing the Installation Test. You must also run the Installation Test when you add a new RTU to your RACO SCADA System, but you only need to test the new RTU.

27 Chapter 3 Running the SCADA System 27 NOTE: During the Installation Test, current programming for the RTU will be downloaded to the Central Station computer. If you have already programmed the RTU via standard telephone or the unit front panel at the monitoring site, this programming will be transferred to the Central Station. It is inadvisable to attempt to program an RTU from the Central Station prior to the Installation Test. See Also: RTU Phone Number List Central Station Number Select All RTUs or a Single RTU to Test You may run the installation test on all RTUs in the system or you may run the installation test on a selected single RTU.

28 28 Chapter 3 Running the SCADA System Password This menu choice allows you to set or remove a password. This feature is provided so that Central Station access to RTU programming and data can be protected from unwanted intrusion. You can still Poll RTU's while password protection is in place. The following procedures are part of this feature: Set Password Remove Password Rearm Password Password Validation Set Password This menu choice allows you to set or change a password. A password will stay in effect until you alter or deactivate it. You also have the option of setting the duration of the password. The duration is the time that you can access any restricted area without being asked for a password again.

29 Chapter 3 Running the SCADA System 29 Example: If you were to set password duration for 15 minutes, you would be able to perform any action within the SCADA System without being challenged for a period of fifteen minutes. At the expiration of that period, you would be challenged upon attempting to access any of the protected features. Some of the restricted areas are: the Programming Menu the RTU Naming Menu the RTU Phone Number Menu Remove Password This menu allows you to remove the password. Once a password is removed, all the restricted areas will be accessible without restriction. You will first be asked to provide the existing password before it can be removed. Immediate Password Rearm A hot key [F5] is provided for you to rearm the system with password protection. Typical use of this function will be when you finish accessing a restricted area and want the password protection to be enabled immediately. You will see a menu after you press [F5]. The menu will allow you to choose between activating the password or aborting the menu. Choosing 'activate' will arm the system with password protection immediately. Otherwise, the password will expire at the end of the time delay. You can only choose [F5] when the prompt line at the bottom of the screen indicates F5:Protect. Otherwise, [F5] will not function. Password Validation This menu asks you for the password before allowing you to access any of the restricted areas. Enter your password as asked and press [ENTER]. If the password you enter is the right password, you will be allowed to proceed.

30 30 Chapter 3 Running the SCADA System Version Information The Version Information menu choice reads out the Software Version and release date of your RACO SCADA System. Please refer to this information if you should have to call RACO for technical assistance. Also on this screen is listed the maximum RTUs which your current software can accommodate. In addition, the "Available Memory" shows you the amount of computer memory in bytes which the SCADA system has available to it. If the amount shown for your system is less than or if you are adding more RTUs than allowable, you should contact RACO Technical Support for assistance.

31 Chapter 4 Polling the RTUs 31 Polling Menu Options Polling is the process of requesting status information from RTUs. You can poll all RTUs in the system or poll just a single RTU. The "Polling Interval" is the time between one complete polling sequence (to all RTUs) and the next sequence. It's common for SCADA systems to poll all of their RTUs once a day, once an hour, or even more frequently depending on the possible rate of change of measured physical properties at the RTU sites. Polling will normally be automatic and will perform poll calls to all RTUs at the operator specified polling interval. However, you may perform an unscheduled poll to all RTUs or to a single RTU by choosing "Perform an Unscheduled Poll Now" from the "Polling" pull-down menu. The choices available under the Polling Menu are: Perform an Unscheduled Poll Now Set Polling Interval and Next Poll Time

32 32 Chapter 4 Polling the RTUs Perform an Unscheduled Poll Now You may perform a poll of all RTUs or any selected RTU(s) at any time you choose. This poll will be logged in the normal way to the local printer at the Central Station and stored in the database on the hard drive. You may choose RTUs in the following manner: - By using the F5:Select key to check all RTUs, then deselecting (via mouse or spacebar) those RTUs you do not wish to poll. - By checking selected RTUs. A poll call to an RTU will get the current status of the RTU. The received status includes the following information: RTU I.D. Number Status of AC Power Alarm Status of All Channels Any Run-time Meter Totals

33 Chapter 4 Polling the RTUs 33 Any Totalizer Totals Current Analog Channel Readings Also received will be information about whether the RTU has been disarmed and if there are no phone numbers in the phone number list.

34 34 Chapter 4 Polling the RTUs Polling Interval Using the number keys, enter the time (in hours:minutes format) that you want to elapse between regularly scheduled polls. The program will then automatically perform a polling sequence to all RTUs in the system every time this interval elapses. Next Poll Time Using the number keys, enter the time at which you want the next poll to occur. This must be entered in 24 hour ("military") format.

35 Chapter 5 Generating Reports 35 Report Menu Options Use this menu to select the type of report and the time interval over which the report will span. The features available under the Report Menu are: Summary of Current Status RTU Report - All Events RTU Report - Polling RTU Report - Alarms View the Last Report File

36 36 Chapter 5 Generating Reports Summary of Current Status Use this function to print the contents of the Status Display Window. RTU Report - All Events Select this option to get a printed report of all events which were logged at the Central Station. Events are defined as all polls, alarms and acknowledgments. You must enter a starting date/time values and an ending date/time value. That's four date and time values in total. Also, you may enter the Operator's name which will be printed on the top of the report. RTU Report - Polling Select this option to get a printed report of all polls made from the Central Station to all RTUs or to the selected RTU. You must enter a starting date/time values and an ending date/time value. That's four date and time values in total. Also, you may enter the Operator's name which will be printed on the top of the report. RTU Report - Alarms Select this option to get a printed report of all alarm calls made to the Central Station from all RTUs or from the selected RTU. You must enter a starting date/time value and an ending date/time value. That's four date and time values in total. Also, you may enter the Operator's name which will be printed on the top of the report.

37 Chapter 5 Generating Reports 37 Start/End Date/Time & Operator's Name The report you request will extract data from the archived database starting from a specific date and time and ending at a specific date and time. When you first open the window for setting the date and time you will notice that both the starting and ending date/time are set to the current time. If you want a report that spans from some time in the past up to now you only have to enter the starting date and time. Enter the Operator's name to have it appear at the top of the report.

38 38 Chapter 5 Generating Reports View the Last Report File Select this option to browse a report you last sent to a file. Consult Start/End Date/Time Send Report & Operator's Name for how to send report to a file. You can examine the report but you are not able to change the contents. You can use cursor keys to navigate around the file. Use the [END] key to move to the very bottom of the file. The [HOME] key will bring you to the top of the file. Several function keys are also available. [F5] allows you to start marking a block of text. You can extend the marked region using the cursor keys, [PGUP], [PGDN], [END] and [HOME]. (Press [F5] again to unmark the text.) Press [F6] to print the marked region. [F7] is a short-cut to quickly jump to a particular line number. Press [F7], and you will be asked to enter a line number. Press [ESC] to return to the main menu.

39 Chapter 6 Programming the RTUs 39 Programming Menu Options Use the Programming pull-down menu to access the functions to check or alter the programming in any RTU in the system. Note that you must have entered a phone number (under the System menu) of any RTU you wish to reprogram. It is assumed that the operator has a good working knowledge of the programmable features of the RTU. A thorough discussion of the programmable features of the RTU is beyond the scope of this document. Please refer to the Verbatim Owners Manual. After you have chosen the source of the programming information and it has been obtained (either from the RTU or from the disk) you will be presented with a menu for the Programmable Features Groups.

40 40 Chapter 6 Programming The RTUs NOTE: It is advisable to conduct an RTU Poll Call following any programming operation to confirm the status of the RTU. This allows the system operator to confirm that the correct programming was sent and is in place for a particular RTU. Also, the Poll Call will log the new data monitoring programming to both the Status File (accessible via F9 function key) and the printer, as well as to the system database. Call for Current Programming If you choose this option a call will be placed to the selected RTU to retrieve it's current programming parameters. You may then use these programming parameters as a basis for changes to individual parameters. Note that the call to the selected RTU will take some significant length of time to retrieve the programming parameters. It is, however, the most reliable way to avoid altering parameters which may have been set by personnel, while visiting the RTU site, at the RTU front panel.

41 Chapter 6 Programming the RTUs 41 Use Programming from Last Session If you choose this option programming parameters will be retrieved locally from the Central Station hard drive. These programming parameters will be those which were last sent to the selected RTU after the programming session. Note that using this option avoids the somewhat time consuming process of retrieving programming parameters from the RTU. Using this basis for the programming parameters will serve to provide a consistent starting basis for parameters. This method will have the effect of overwriting or possibly "correcting" any changes made by personnel at the front panel of the RTU. Use Default Programming If you choose this option the standard RTU default programming will be used as the basis for any changes you may make. This option is normally used only on start-up when the RTU in the field has never been programmed. Refer to the Verbatim Owners Manual for information on the default programming parameters.

42 42 Chapter 6 Programming The RTUs Programmable Feature Groups The features available under the Programming Menu are: RTU Analog Input Parameters RTU Contact Input Parameters RTU Dialout Telephone Numbers RTU Alarm Delays and Timers Other RTU Programming Send Programming to RTU

43 Chapter 6 Programming the RTUs 43 RTU Analog Input Parameters Select this option to enable or disable an analog channel, set high and low analog alarm setpoints, set the input signal type (4-20 milliamps, 0-1 volt, or RACO temperature sensor), and set the gain and offset used in calculating analog values. When this option is selected you will open a window allowing programming of the following items: Disable Channel Input Signal Type Low Setpoint High Setpoint Use default gain/offset Select the analog channel which you wish to reprogram. Caution: Different RTUs may have different numbers of contact and analog channels. The first analog channel in one RTU may be channel 5 while in another channel the first analog channel may be channel 9.

44 44 Chapter 6 Programming The RTUs Disable Channel Use the [SPACEBAR] to toggle between analog channel disabled ("YES") and analog channel enabled ("NO"). A disabled analog channel will cause no alarms and it's analog reading will not be reported. Input Signal Type Enter a number between 0 and 2 to select a standard Input Signal Type. The available Input Signal Types are listed in a window below the analog parameters menu whenever "Input Signal Type" is highlighted. NOTE: Changing the Input Signal Type will alter the previously stored gain/offset parameters as well as the default Low and High Setpoints. Low Setpoint Use the [SPACEBAR] to toggle between "on" and "off". When The Low Setpoint is "on" a sub-menu will appear below the analog parameters menu. Enter the desired Low Setpoint into this sub-menu. NOTE: The entered Setpoint must be consistent with the gain/offset. High Setpoint Use the [SPACEBAR] to toggle between "on" and "off". When The High Setpoint is "on" a sub-menu will appear below the analog parameters menu. Enter the desired High Setpoint into this sub-menu. NOTE: The entered Setpoint must be consistent with the gain/offset.

45 Chapter 6 Programming the RTUs 45 Use Default Gain/Offset Use the [SPACEBAR] to toggle between "Yes" and "No". When "Yes" is selected the gain and offset will be set such that the lowest input will yield a reported value of 0.0% and the highest input will yield a reported value of 100%. When "No" is selected a sub-menu will appear to allow the entry of coordinates which will be used to determine the gain and offset. See Also: Coordinate Entry Disable Channel Input Signal Type Low Setpoint High Setpoint Analog Math Entering Setpoints Enter a setpoint value for which you wish an alarm to be generated. For a low setpoint the input must be BELOW the setpoint in order to cause alarm. For a high setpoint the input must be ABOVE the setpoint to cause a alarm. The low setpoint is sometimes referred to as the "falling" setpoint since the alarm is generated when the input "falls" below the setpoint. Correspondingly, the high setpoint is sometimes call the "rising" setpoint. Note that the acceptable values of setpoints will be affected by the gain and offset for the channel. Non-default gain and offset are entered from the "Use default gain/offset" choice in the "Analog Parameters" menu. If you are using the default gain and offset for the chosen input signal type then the setpoints will be entered in percent from 0 to 100. If you have entered a non- default gain and offset then the setpoint will be entered in the units you have chosen when entering the gain and offset. Coordinate Entry You must enter four coordinates which will be used to determine the non-default gain and offset. (Note: this set of steps is not necessary for inputs using a RACO Temperature Sensor, since these values will be automatically inserted if the input signal type 2 is selected.) In general, you will need to determine the desired reported numerical values corresponding to two widely separated ("LOW END" & "HIGH END") input signal values. Often this will be available from the overall system specifications. In other cases, this will be determined (or revised) based on actual on-the-spot observations from the RTU site. Scaling information which you may have originally entered based on your system

46 46 Chapter 6 Programming The RTUs specifications may later be easily "fine tuned" based on real world observations. For a more "Engineering" or "Mathematical" based perspective on coordinate entry and gain/offset determination see the section on Analog Math below. You may find it easier to establish the gain and offset at the RTU site where actual measured coordinates may be entered into the RTU at it's front panel. Then you can use the RACO SCADA System to get the programming information from the RTU via the menu choice which calls the RTU for current programming. As an alternative, you could get the coordinate information from the RTU by calling it and getting a voice readout of the coordinate information. If it's possible for you to know the actual measured analog sensor data at the central station by some means, such as by a remote flow meter, then that information could be put together with the readings from the RTU to enter the necessary coordinate points. Two different coordinate pairs for sensor data and reading value would have to be obtained at two different times. Analog Math It may be useful, in comprehending the process of establishing the scaling factors, to visualize a graph which relates the water level in a tank to the input from a 4-20 ma transducer. To establish the relationship on such a graph, it is necessary to define two

47 Chapter 6 Programming the RTUs 47 separate points, or coordinate pairs ideally at two widely separated points on the graph. For such a linear relationship any point on the "reading" (y) may be calculated from the formula : y = mx + b where m is the gain and b is the zero crossing point or Input (ma) -> offset. The gain may be calculated from: m = (y2-y1)/(x2-x1) where x1,y1 is one coordinate pair on the graph and x2,y2 is the other.0 Therefore, when you have chosen to enter non-default coordinates you are in fact setting the gain factor. This gain factor is taken along with the input signal type you have chosen which will define both the gain and offset. Entering Individual Coordinates You must enter four coordinates which will be used to determine the non-default gain and offset. Enter the "LOW END" input value and the corresponding known low reading value. Then enter the "HIGH END" input and the corresponding known high reading value. As an example, if you know that an input value of 0.0 volts should give a corresponding reading of 10.0 feet of water level then enter 0.0 followed by Then, if you know that an input of 1.0 volts should give a corresponding reading of 52.0 feet of water then enter 1.0 followed by 52.0.

48 48 Chapter 6 Programming The RTUs RTU Contact Inputs Select this option to set the way in which the status of a contact input is interpreted. The options are: Normally Closed (on open contacts) Normally Open (on closed contacts) No Alarm (Reports on/off status only) Runtime Meter (Reports runtime) Pulse Totalizer (Reports total scaled pulses) See Also: Contact Criteria Runtime Initial Value Totalizer Setup

49 Chapter 6 Programming the RTUs 49 Normally Closed The RTU will go into alarm state if the input for that channel stays open for the length of the trip delay for that channel. Normally Open The RTU will go into alarm state if the input for that channel stays closed for the length of the trip delay for that channel. No Alarm Neither open nor closed contacts for the channel will trigger an alarm. The contact status will be reported as "ON" or "OFF". Runtime Meter The RTU will keep track of and report the amount of time that the contacts for the channel are closed. Runtime Initial Value A runtime meter accumulates the total length of time that a channel's contacts have been closed. Normally this corresponds to the length of time that a device such as a pump has been running. The default initial value for a runtime meter is 0, but the initial value can be set to any number between 0 and hours. Pulse Totalizer The RTU will keep track of and report the number of contact closures that occur on the channel. Note that only 8 pulse totalizers are allowed in each RTU. Totalizer Setup If you select a totalizer input for a channel you may also enter a totalizer initial count, a totalizer pre-scaler factor and an alarm setpoint. The initial value will be zero unless you enter some other value. Entering an initial count

50 50 Chapter 6 Programming The RTUs may be useful in making the RTU totalizer agree with some other type of pulse counting instrument which may not be re-settable or which may be maintaining a "lifetime" pulse count such as for total flow since system start-up. Setting the pre-scaler to something other than 1 is like putting a hardware pre-scaler "in front" of your totalizer input. The pre-scaler acts as a divisor. Thus, if you set the pre-scaler to 1000 it will take 1000 actual input counts to register as 1 count reported by the RTU. This feature is useful if the counting instrument produces at a rate much faster than "reasonable" human units. For instance, if a flow meter generated a pulse for every gallon of flow but you were more interested in kilo-gallons of flow you could set the pre-scaler to You could also set a Setpoint for the totalizer so that when a certain count was reached the RTU would notify the Central Station and/or personnel that count had been reached.

51 Chapter 6 Programming the RTUs 51 RTU Dialout Telephone Numbers Enter the telephone numbers that the RTU should call when an alarm occurs. Some types of telephone exchanges require that there be a delay during the dialing of a telephone number (for example, to allow enough time to establish an outside connection). To insert such a delay, put a comma (,) in the number at the appropriate place.

52 52 Chapter 6 Programming The RTUs RTU Alarm Delays and Timers Reset On/Off If an alarm condition persists after acknowledgement, and this option is set ON, a new alarm will be triggered after the Reset Time has elapsed. Press the [SPACEBAR] to toggle between ON and OFF. Reset Time The amount of time after an alarm is acknowledged that an alarm condition must persist before a new alarm is triggered. Global Trip Delay Sets all individual channel alarm trip delays. To set a channel to a value different from the Global alarm trip delay, first set the Global alarm trip delay, then set the desired value for the individual channel.

53 Chapter 6 Programming the RTUs 53 Power Fail On/Off Press the [SPACEBAR] to toggle between ON, which will cause an alarm if power fails for longer than the Power fail trip delay, and OFF, which will prevent power failure alarms. Power Fail Trip Delay The length of time that the RTU will wait after AC power is lost before signalling an alarm. Individual Channel Trip Delays Enter the time interval between the start of an alarm violation (normally open contact becomes closed, normally closed contact becomes open, analog value too high or low) and the time when the RTU should assume that an alarm condition actually exists and begin dialing. The default is 2 seconds. Each channel can have a different trip delay, or they can all be set to the same value with the Global alarm trip delay. See Also: RTU Delays Contact Criteria

54 54 Chapter 6 Programming The RTUs Other RTU Programming The features available under Other RTU Programming are: RTU dialing mode (pulse, tone, or high-speed tone) Message Repeats (1-20) Time Between Calls ( minutes) Dialing Delay Length (1-10) Rings Before RTU Answers (1-20) Autocall Time Between Autocalls ( hours) Initiate Autocall Now? Alarms Armed/Disarmed Station ID Number String Return to Normal Call Automatic Speed Select Data or Voice Answer

55 Chapter 6 Programming the RTUs 55 Acknowledged Call Number of Retries (1-6) Other Unmodifiable Parameters RTU Dialing Mode The Verbatim RTU is capable of dialing out in any of three modes: Pulse (similar to a rotary telephone) Tone (similar to a touch-tone telephone) High Speed Tone (same as tone, except at a high rate of speed) Generally Tone or High Speed Tone dialing will be preferable unless the telephone exchange in the area only supports pulse dialing. Message Repeats Enter a number between 1 and 20 to set the number of times that the RTU will repeat the alarm message when making a voice alarm call. The default value is 3. Time Between Calls Enter a number between 0.1 and 99.9 to determine the number of minutes the RTU waits after making a voice alarm call before making another call. During this waiting period the RTU is listening for acknowledgement calls from personnel or from the Central Station. The default value is 2.0 minutes. Dialing Delay Length Enter a number between 1 and 10 to determine the delay length in seconds represented by a comma in any of the telephone numbers stored in the RTU. The default value is 1. Rings Before RTU Answers Enter a value between 1 and 20 to set the number of rings that the RTU waits before answering an incoming telephone call. The default is 1. Autocall Use the space bar to toggle between ON and OFF. If Autocall is ON, the RTU will periodically make test calls to verify proper phone line and dialer operation.

56 56 Chapter 6 Programming The RTUs Time Between Autocalls Enter a value between 0.1 and 99.9 hours to set the interval at which Autocalls are made. Initiate Autocall Now? If you wish an Autocall to occur immediately after the programming has been sent to the RTU, use the [SPACEBAR] to toggle this option to YES. The next Autocall, after the one initiated by this action, will then occur after the Time Between Autocalls has elapsed. If you toggle this to NO, the next Autocall will take place whenever it would normally have taken place. Note that no Autocall will occur unless Autocall ON/OFF is set to ON. Alarms Armed/Disarmed Use the [SPACEBAR] to toggle between RTU alarms ARMED or DISARMED. Note that if alarms are DISARMED no alarm calls will be placed by the RTU. Station ID Number String Use the number keys to enter a number string that will be used by the RTU to identify itself when it makes a voice call. Return To Normal Call Use the [SPACEBAR] to toggle between ON and OFF. When ON is selected this causes the RTU to place a call to the Central Station when a channel which caused an alarm call returns to normal condition. Automatic Speed Select Use the [SPACEBAR] to toggle between choices. If this option is set to ON, and the RTU experiences consistent failures placing calls to the Central Station at 1200 baud, it will switch to 300 baud. Data or Voice Answer Use the [SPACEBAR] to toggle between choices. For normal operation in a RACO SCADA System, this option must always be set to DATA. If it is set to VOICE, the Central Station will be unable to make calls to the RTU. However alarm calls from the RTU may still be made to the Central Station.
