Runtime
network output SNVT_time_hour nvoRuntime
This optional output network variable provides the operating hours of the
pump, or with double pumps, the time during which at least one pump was
running. The counter is reset to 0 h after 65535 h.
Value range
0 – 65535 h (in 10 h steps), (max. 2730 d or 7.48 a).
Transmission
This value is transmitted whenever a change is made.
Transmission frequency
The minimum network variable transmission interval can be set by describing
the nciMinOutTm configuration input with a valid clock.
Preset service type: unacknowledged
Fault states of the pump
network output SNVT_dev_fault nvoPumpFault
This optional output network variable provides bit-coded error information of
the pump. Errors can be device errors or supply errors.
Value range
Transmission
This value is transmitted whenever a change is made.
