Modbus Registers 401900 to 401950 provide ACS operation status information and are
Read only. They must never be written to. See Table 3.
Table 3: ACS Modbus Registers 401900 to 401950
Register No. Register Name
Description
401900 None Not used.
401901 CalcCPM Pump cycles per minute x 100.
401902 GT_CyclesL Grand Total cycles low word.
401903 GT_CyclesH Grand Total cycles high word.
To calculate the Grand Total, use the following formula:
Grand Total = (10000 * GT_CyclesH) + GT_CyclesL.
401904 Batch_CyclesL Batch Total cycles low word.
401905 Batch_CyclesH Batch Total cycles high word.
To calculate the Batch Total, use the following formula:
Batch Total = (10000 * Batch_CyclesH) + Batch_CyclesL.
401906 AVG_Press Average of last 5 pressure readings.
401907 Rev SOFTWARE VERSION.
401908 EventFlag
Modbus Display only.
7 = Start Event.
8 = Stop Event.
401909 RunningFlag
1 = The motor is rotating.
0 = The motor is stopped.
401910 AutoSlpStat Status of the AutoSleep input. 1 = the AutoSleep input is active (low).
401911 CalcFlow Current flow rate x 100 in GPM or LPM.
401912 XducerValidFlg
1 = Pressure transducer is valid (> 2mA).
0 = Pressure transducer has failed (< 2mA).
401913 to
401919
None Not used.
401920 ToothStat Status of the Position Sensor. The motor must be rotating for the system
to determine the validity of the position sensor.
1 = Valid; the ACS is receiving Position Sensor pulses.
0 = Failed; the ACS is not receiving Position Sensor pulses.
401921 PLC_ID Modbus node number assigned to this ACS.
401922 ResetStat Status of the ACS Reset input pin. 1 = the Reset pin is active (low).
401923 TDCStat Status of the TDC (Top Dead Center) Sensor. The motor must be rotating
for the system to determine the validity of the TDC Sensor.
1 = Valid; the ACS is receiving TDC Sensor pulses.
0 = Failed; the ACS is not receiving TDC Sensor pulses.
