Description Attribute
Acceleration
This element serves a feedback that the pump rotation accelerates.
CleanValveOpen
This element serves a feedback about the open state of the cleaning valve.
Deceleration
This element serves a feedback that the pump rotation decelerates.
FlushValveOpen
This element serves a feedback about the open state of the flush valve.
GasDilValveOpen
This element serves a feedback about the open state of the gas dilution valve.
InletValveOpen
This element serves a feedback about the open state of the inlet valve.
NoRotation
This element serves a feedback that the pump stands still.
OutletValveOpen
This element serves a feedback about the open state of the outlet valve.
ProcessIsActive
This element serves a feedback that the process is active.
PumpActivation
This element serves a feedback about the activation state of the pump. The activation state takes into account that control mechanisms are active. Never the less the pump is not necessarily running
PumpDirection
This element serves a feedback of the pumps direction of rotation.
PumpOperation
This element serves a feedback about the operation state of the pump. In the operation state the pump rotor is rotating.
PumpPowerMax
This element serves a feedback of pump operating at maximum power.
PumpSpeedMax
This element serves a feedback of pump operating at maximum speed.
PumpSpeedMin
This element serves a feedback that the pump operates at minimum speed.
PurgeValveOpen
This element serves a feedback about the open state of the purge valve.
RatedSpeed
This element serves a feedback that the pump rotation is at rated speed.
StandBy
This element serves a feedback about the process standby of the pump. In the stand by state the pump is ready for operation.
StandBySpeed
This element serves a feedback that the pump rotation is at standby speed.
TargetSpeed
This element serves a feedback that the pump is at target speed.
VentValveOpen
This element serves a feedback about the open state of the vent valve.
