6 Gas Chromatograph User Program (for ROC89) ROC89 Remote Operations Controller Instruction Manual (Form A6116) Part Number D31154X PROGRAM OVERVIEW The Gas Chromatograph User Program communicates using Modbus Protocol directly to a Gas Chromatograph (GC). The ROC89 will poll data from the GC, validate the data from the GC, and update the appropriate station database with the data. The program is capable of polling up to 6 streams. The maximum number of streams that the program will process is determined by the number of stream licenses available in the ROC89 unit. The license key adminstrator displays the number of streams available in the App Code Field. For more information, refer to Section 2.1. Each stream must be assigned to a station in the ROC89 database. This allows the ROC89 to log the gas quality, gas component data, heating value, and specific gravity. The program configuration is accomplished through a display screen provided by ROCLINK 8 software, including gas quality configuration and station assignment. Alarm logging may be enabled on the GC Stream Data screen for the stream. 1.5 COMMUNICATIONS WIRING The Gas Chromatograph must be connected to the communications port on the ROC89 unit using 12 AWG, or smaller, wire. The wiring for a EIA-232 (RS-232) to Daniel 235A Gas Chromatograph is shown in Figure 1. ROC89 EIA-232 (RS-232) Port Rx Daniel 235A Jumper J6 6 Tx 5 GND RTS 4 DTR 3 S IN_2 GND 2 S OUT_2 1 Figure 1.

11 Gas Chromatograph User Program (for ROC89) SECTION 3 CONFIGURING THE PROGRAM This section details how to configure the Gas Chromatograph User Program using ROCLINK 8 Configuration Software. Note that the user data points and associated parameters will not be available in ROCLINK 8 software until the user program has been downloaded as instructed in Section USER PROGRAM CONFIGURATION Once the program is loaded into the ROC, the two configuration screens become available from the Configuration Tree Menu. To access the configuration screen, select User Program > Program #, GCInterface > Display #,GC Configuration. See Figure 4. Figure 4. Configuration Tree Menu The GC configuration screen allows the user to enable the automatic configuration of the communication port and modbus parameters. The user is also able to specify which communications port will be used, assign streams to stations, specify the gas composition, and specify the polling interval. The screen also displays the program status. Refer to Figure 5. Each field on the GC Configuration screen is described on the following pages. Rev May/5 7

12 Gas Chromatograph User Program (for ROC89) Figure 5. GC Configuration Screen Component ID assigns a number to each gas component for use in Component Data Tables 1 and 2. If the Gas Chromatograph will not return a value for a gas that the ROC89 supports, enter 255. Autoconfig starts the automatic configuration of the Communication Port and the Modbus Master parameters appropriate for a Daniel Gas Chromatograph. For more information on Autoconfig, see Section The user may disable Autoconfig and manually set the communication port and Modbus Master parameters in ROCLINK 8 software. The user may also enable Autoconfig, allow the user program to configure these parameters, and then change them in ROCLINK 8 software to suit the application. Hexane Split Enable allows the automatic setting of a pre-defined split percentage of the Hexane and heavier gases for use with Daniel Gas Chromatographs. The pre-defined split percentage is given in the table below. If the user wants to use a non-standard Hexane split, the user will have to set the Hexane Component ID to 255, set the Hexane (+) Component ID to a specific value, set the Heavy Gas Option to enable for the appropriate station, and fill in the specific percentages for heavy gases in the station. Table 1. Pre-Defined Split Percentage COMPONENT ID HEXANE % HEPTANE % OCTANE % NONANE % DECANE % Alarm Bypass tells the user program how to handle alarm values. When selected, it allows the ROC AGA calculations to be updated even if the Alarm 1 or 2 field in the GC displays an alarm. 8 Rev May/5

13 Gas Chromatograph User Program (for ROC89) Max License Checkout specifies the maximum number of GC streams to be reserved for this program. The number of streams that can be checked out must not exceed the number available in the License Key Administrator screen in ROCLINK 8 software. The GC Address field specifies the RTU address to be used in the Modbus Master Table. The Modbus Master Table will use the RTU address for the ROC89 unit to communicate with the GC. If the GC Address field is set to, the polling of the GC will be disabled. The user must configure this parameter before the program will poll data and write to the station. This parameter will be used in autoconfiguration; see Section Modbus Location specifies which Modbus Register Table will be used. The default is 24. The range is This parameter will be used in autoconfiguration; see Section Polling Interval is the amount of delay in seconds before asking for the next set of results. The GC typically takes 3 to 6 minutes to update the results. Next Poll Request displays the number of seconds remaining until the next polling cycle. After a poll cycle is complete, this field is reset to the number stored in the Poll Interval parameter. Comm Timeout is the time to wait in seconds for the GC to respond to a Modbus poll. The BTU Low Limit is the minimum heating value accepted by the ROC89 unit for an AGA calculation update. Heating values sent by the GC which are lower than this number are considered to be erroneous and will not be forwarded to the station. The BTU High Limit is the maximum heating value accepted by the ROC89 unit for an AGA calculation update. Heating values sent by the GC which are higher than this number are considered to be erroneous and will not be forwarded to the station. Total Mole % Deviation is the difference plus or minus from 1% that is allowable for both Total Unnormalized Mole % and mole sum values. The value will be subtracted and added to 1% to determine the range. The default is 2% deviation. Comm Port # specifies which of the ROC89 communication ports will be used for the EIA-232 (RS- 232) or EIA-485 (RS-485) connection to the GC. This parameter will be used in autoconfiguration; see Section This parameter should be set before turning on the user program. If the user program is on and you need to change the Comm Port #, change it, stop the program, and restart it. NOTE: Unlike other user programs, the Comm Port Owner will be Modbus Master. The Comm Port Owner should not be user program. Station Map allows the user to assign streams to stations in the ROC89 unit. The gas composition data from the specified stream will be sent to the historical segment which has been assigned to the station in the Station Setup screen in ROCLINK 8 software. The stream range is 1-6. The station number here matches its number in the Station Setup screen. A value of will disable updating of a station. The user must configure this parameter before the program will poll data and write to the station. Rev May/5 9

14 Gas Chromatograph User Program (for ROC89) Autoconfiguration When Autoconfig has been started, the user program will automatically configure the communication ports and Modbus parameters in ROCLINK 8 software. The Communications Port that has been specified in the Comm Port # field will be configured to the following values: Baud Rate: 96 Data Bits: 7 Stop Bits: 1 Parity: Even Key-On Delay: 2 msec Key-Off Delay: 2 msec Port Owner: Modbus Master. The Modbus configuration parameters will be set to the following values: Transmission Mode: ASCII Byte Order: MSB First Event Log Enable: Disabled Master Starting Request Number: 1 Master Number of Requests: 8 Master Continuous Polling Enable: Disabled. The Modbus Master Table is autoconfigured from the values in the Comm Port # and GC Address fields. The Modbus Register to TLP Mapping assigns TLPs to registers. The TLPs are mapped to the register table specified in the Modbus Location field. The parameters necessary for this user program will be mapped to the registers automatically. When the autoconfiguration process is complete, the autoconfig parameter is disabled GC Stream Data One iteration of the GC Stream Data display screen is available for each active stream in the GC. The screen can be accessed on the Configuration Tree Menu, by selecting User Program > Display#1,GC Stream Data. The user may move from one stream to another through the list on the Configuration Tree Menu or the Point Number drop down box. The only parameter that can be set on this display screen is Alarm Logging Mode. The user may enable alarm logging with SRBX (Spontaneous Report By Exception) notification. One alarm will be generated, regardless of the number of different errors that may occur in the time before the alarm is cleared. SRBX will be issued based on the Alarm Logging Mode (SRBX on Set, Clear, or both). For an alarm to be generated, such as for a Poll Sequence Failure error, the current stream logical needs to have its Alarm Logging Mode parameter enabled. The GC Stream Data screen displays the User Calcs, Stream Data, Diagnostics, Calibration status, Component Data, Component Mask, and Error Code (see table below) for the stream. The Component 1 Rev May/5

15 Gas Chromatograph User Program (for ROC89) Data displays the Component ID for that component in Component Data Table 1 and 2, the Mole % value, and Yesterday s Average flow value. See Figure 6. Figure 6. GC Stream Data Screen Table 2. Error Codes. ERROR CODE TITLE DESCRIPTION All checks passed Any AGAs assigned to the current stream will be updated and their Fpv(s) recalculated (if the sample minute has changed). 1 Poll Sequence Failure One or more of poll blocks were unsuccessful (not an 8). 2 Alarm Check Failure There are non-bypassed alarms in effect. 3 Calibration Check Failure The unit is in calibration mode. 4 Sample Minute Changed The sample minute changed while collecting data. 5 Total Un-Normalized % Failure The total un-normalized mole percentage is not within range. 6 Mole Sum Check Failure The mole sum is not within the range. 7 BTU Range Failure BTU is not within the specified ranges. 8 Specific Gravity Range Failure Specific Gravity is not within the specified ranges. After configuring the streams and pressing Apply, save the program to Flash Memory on the ROC Flags screen to save the configuration to permanent memory, in case you must perform a Cold Start.

16 Gas Chromatograph User Program (for ROC89) Validation of GC Data When the polls are complete, the program will perform validation to ensure the polling was successful and data is correct. The following checks will be made before GC stream data is copied to the station. The Communication Status (Point 121, Parameter 6, 12, 18, etc.) must return valid responses (value of 8) for all registers polled. If errors are present, Station(s) will not be updated. If Bypass Alarm 1 (Point 65, Parameter 11) is disabled, the Alarm Flag 1 (Point 66, Parameter 18, bits 14 & 15) from the GC will be checked for errors. If errors are present, Station(s) will not be updated. If Bypass Alarm 2 (Point 65, Parameter 12) is disabled, the Alarm Flag 2 (Point 66, Parameter 19, bits, 1, 2 & 3) from the GC will be checked for errors. If errors are present, Station(s) will not be updated. The Calibration Flag (Point 66, Parameter 2) will be checked to ensure it is in the Analysis State. If it is not in the Analysis State the Station(s) will not be updated. The Starting Sample Minute (Point 66, Parameter 17) must be different than the previous, or the station(s) will not be updated. Both the Starting Sample Minute (Point 66, Parameter 17) and Ending Sample Minute (Point 66, Parameter 16) in the poll must match, or the station(s) will not be updated. The current Stream Number (Point 66, Parameter 2) must be assigned to a station and have a license key. The Total Un-Normalized Mole % (Point 66, Parameter 9) must be within plus or minus Total Mole % Deviation (Point 65, Parameter 14) of 1%. If outside the limits, the Station(s) will not be updated. The Mole Sum (Point 66, Parameter 21) must be within plus or minus Total Mole % Deviation (Point 65, Parameter 14) of 1%. If outside the limits, the Station(s) will not be updated. The BTU MJ Value (Point 66, Parameter 4 or 5, depending on Wet vs. Dry) must be between BTU MJ Low (Point 65, Parameter 9) and BTU MJ High (Point 65, Parameter 1). If outside the limits, the Station(s) will not be updated. The Specific Gravity (Point 66, Parameter 6) must be between.7 and If outside the limits, the Station(s) will not be updated. Each GC stream component will be copied to its corresponding component in the station, with the exception of neo-pentane. Neo-pentane will be added to the iso-pentane component and then copied to the station. The heating value and specific gravity will be copied to the appropriate stream, as well. 12 Rev May/5

17 Gas Chromatograph User Program (for ROC89) 3.2 ROCLINK 8 CONFIGURATION Before running the user program, the user must select Meter > Setup > Station. Select the Station Number to which the stream has been assigned. Open the Gas Quality tab, and configure the following parameters. The Heating Value will determine which BTU Value (dry or saturated) will be copied to the station. If the value is set to dry, the dry heating value will be copied. If it is set to Wet, the saturated heating value will be copied. If the type is set to anything else, the user program will set the type to Dry, and proceed to copy the dry value to the station. The Gas Quality will be set to Live Gas Quality by the program, when the data is copied to the station. If the Auto-configure option has not been selected in the user program configuration screen, select the Heavy Gas Option to allow for Hexane and other heavy gases. Rev May/5 13
