BrowsePath 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.
