MP_EnergyValveV4_2_Configuration

This function block is used to configure the Energy Valve actuators EV..R2+.. with firmware 4.2.0 or higher. For more information please visit 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.

nSensor1PassiveType_Write	E_MP_EV_V4_Sensor1PassiveType	Only available if nSensor1Type_Write <> MPBus_EV_SensorPassive_None.
rVmin_Write	LREAL	Min. setpoint in % (0...Vmax). Vmin must be smaller than Vmax.
rVmax_Write	LREAL	Max. setpoint in % (25...100). Refers to Vnom and is taken into account when control mode = flow control.
rPmax_Write	LREAL	Max. setpoint in % (5...100). Refers to Pnom and is taken into account if control mode = power control.
nDeltaTLimitation_Write	E_MP_EV_V4_DeltaTLimitation	Determines whether the device responds to a low delta T.
nUnitSelection_Write	E_MP_EP_R_R6_UnitSel	Scaling for rAbsoluteFlow_UnitSel.
rSetpointDeltaT_Write	LREAL	Setpoint Delta T in K (0...55). Is taken into account if the delta T limitation is active (not disabled).
