Modbus Register Types
Pump OFF Setpoint (R41,430 – R41,435)
The OFF setpoint level (P113) for the referenced pump relay.
The setpoint is scaled from 0 to 10,000 (0 to 100% of span multiplied by 100). So 54.02% is
shown in the register as 5402.
Pumped Volume (R41,440 – R41,443) [MR 200]
The pumped volume registers hold the current total for all of the pumps associated
with a level point. These registers are available only if operation is set to pumped
volume (P001 = 7).
These volumes can become very large. Therefore, two registers are used to hold the
value. See
Unsigned Double Precision Integer (UINT32)
on page 107 for more information.
The value in the registers is given as an integer value but must be interpreted as having
the number of decimals set in P633 (LCD Totalized Decimal Position): this number can be 0
to 3. Ensure that your software accounts for these decimal places before you report the
pumped volume totals.
Pump Hours (R41,450 – R41,461)
The number of running hours for the referenced pump relay. The hours are given to three
decimal places, so the integer must be divided by 1000 to get the correct value. For
example 12,340 represents 12.34 hours.
This value comes from parameter P310. See page
157
of the
Parameter Reference
section
for details.
Pump Starts (R41,470 – R41,475)
The number of pump starts for the referenced pump relay.
This value comes from parameter P311. See page 157 of the
Parameter Reference
section
for details.
