MP_JR_Actuator_Configuration

This function block is used to configure the rotary actuators for butterfly valves JR. Further information can be found at www.belimo.com.

MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bStart activates communication with the MP-Bus device. bBusy indicates that the function block is active. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.

Name	Type	Description
bBusy	BOOL	This bit is set for as long as the function block is active.
bError	BOOL	This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable.
iErrorId	MP_ERROR	This output outputs an error code in the event of an error. bError goes TRUE at the same time.
nBusFailAction	E_MP_EV_V4_BusFailAction	Bus failure action.
nCommunicationWatchdog	UINT	Communication monitoring in sec (5...3600).
bSetpointSource	BOOL	TRUE = bus; FALSE = analog
rMaximumLimit	LREAL	Maximum limit in s (30..100).
nSensor1Type	E_MP_EV_V4_Sensor1Type	Sensor 1 Type
nSensor2Type	E_MP_EV_V4_Sensor1Type	Sensor 2 Type
nSensor1PassiveType	E_MP_EV_V4_Sensor1PassiveType	Only available if nSensor1Type_Write <> MPBus_EV_SensorPassive_None.
