Address Description
40001 ...................... High bytes for Accumulated odorant injected, combine with address 40002 for total.
40002 ...................... 6300GE/LE = .XXXXX, 7300GE/LE = X.XXXX, 8300GE/LE = XX.XXX (lbs),
6300GM/LM = .XXXXX, 7300GM/LM = X.XXXX, 8300GM/LM = XX.XXX (kg)
Note: Low bytes only, combine with address 40001 for total odorant injected.
40003 ...................... High bytes for Accumulated flow, combine with address 40004 for total.
40004 ...................... 6300GE = .XXXXX, 7300GE = X.XXXX, 8300GE = XX.XXX (MMCF/hr),
6300GM = X.XXX, 7300GM = XX.XXX, 8300GM = XXX.XX (M
3
/sec) 6300LE = XXX.XX,
7300LE = XXXX.X, 8300LE = XXXXX (gallons), 6300LM = XXX.XX, 7300LM = XXXX.X,
8300LM = XXXXX (liters), 6300/7300/8300LE (PPMV mode) = XXXXX (gallons),
6300/7300/8300LM (PPMV mode) = XXXXX (liters)
Note: Low bytes only, combine with address 40003 for total accumulated flow.
40015 ...................... High bytes only, combine with address 40016 for total odorant injected.
40016 ...................... 6300 = .XXXX, 7300 = X.XXX, 8300 = XX.XX (lbs/kg)
Note: Low bytes only, combine with address 40015 for total odorant injected.
40017 ...................... Model number format: 63XX = 6300, 73XX = 7300, 83XX = 8300. XX= 11= GE,
XX=12=GM, XX=21=LE, XX=22=LM. Example: 6311 = 6300 Gas English,
7322 = 7300 Liquid Metric
40019 ...................... 6300 = XX.XXX, 7300 = XXX.XX, 8300 = XXXX.X (cc)
Parameter functions
The result data functions available via Modbus are listed below. The registers are accessed using Modbus
functions 3, 6, and 16.
Note: The system must be stopped in order for any parameter changes to be accepted. An exception re-
sponse will be returned if a parameter change query is issued while the system is running. Once the param-
eter changes have been made, use coil 00009 to save the updated parameters before restarting the system.
