zPUMP_STATION_DATA_TYPE Station Configuration DataΒΆ
iNumOfPumps (number of pumps)
Data type: INT
This variable defines the number of pumps in the station.
byAutoChgStyle (autochange style)
Data type: BYTE
| Style | Short description | Description |
|---|---|---|
| 0 | None | Autochange function disabled. |
| 1 | Fixed | The starting sequence is shifted periodically at pre-defined intervals Autochg interval. In traditional pump control. |
| 2 | Runtime diff | The starting sequence is rearranged when the difference between the runtimes of two pumps exceed a limit, Runtime difference. In the new sequence, the pump with the lowest runtime will be started first, the pump with the highest runtime will be started last. |
| 3 | All stop | The starting sequence is shifted every time the pump stops. |
timAutoChgInterval (auto change interval time)
Data type: TIME
Time interval to elapse for the fixed autochange to activate.
timRuntimeDifference(runtime difference time)
Data type: TIME
Maximum permited runtime diff between the two pumps in the network.
rSleepBoostRef(sleep boost reference)
Data type: REAL
Speed step from the sleep function block. This step is used as additional setpoint to the pump before going to sleep mode.
byOperationMode(operation mode)
Data type: BYTE
Stores the operating mode of the pump boost control.
