MP_EnergyValveV4_Configuration
This function block is used to configure the Energy Valve actuators EV..R2+.. (V4). 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.

Name | Type | Description |
---|---|---|
MP_Address | USINT | MP-Bus address of the slave. |
bStart | BOOL | A positive edge starts the function block. If this remains continuously TRUE, the function block will be activated cyclically with a period specified by the time in TMPolling. |
bRead_Write | BOOL | If FALSE then READ only; if TRUE then READ and WRITE. |
strDataKL6771 | The data structure with which the KL6771() function block must be linked. | |
rVmax_Write | LREAL | Max. setpoint in % (25...100). Standard 100 %. Refers to Vnom and is taken into account when control mode = flow control. |
rVmin_Write | LREAL | Min. setpoint in % (0...Vmax). Vmin must be smaller than Vmax. |
bSetpointSource_Write | BOOL | TRUE = bus; FALSE = analog. |
nSensor1Type_Write | Sensor 1 type | |
nControlMode_Write | Control mode | |
rBusFailPosition_Write | LREAL | Bus failure position in % (0...100). Not functional (reserved for future extensions). |
nCommunicationWatchdog_Write | UINT | Communication monitoring in s (0...3600). Not functional (reserved for future extensions). |
bSetpointSource_Write | BOOL | TRUE = bus; FALSE = analog. |
rPmax_Write | LREAL | Max. setpoint in % (5...100). Standard 100 %. Refers to Pnom and is taken into account if control mode = power control. |
nDeltaTLimitation_Write | Determines whether the device responds to a low delta T. | |
rSetpointDeltaT_Write | LREAL | Setpoint Delta T in K (0...60). Standard 1.0K. Is taken into account if the delta T limitation is active (not disabled). |
rSetpointAbsFlowDeltaT_Write | LREAL | Setpoint Abs flow Delta T in l/s (0...100.000). Considered when Delta T limitation is set to "Delta T Manager scaled". |
bSelectMeterRegister_Write | BOOL | FALSE = certified meter; TRUE = lifetime meter. |
