MP_EPIV_V4_Configuration

MP_EPIV_V4_Configuration 1:

This function block is used to configure the 2-way EPIV V4 DN 15..50 EP..R2+(K)BAC. 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

DataKL6771

The data structure with which the KL6771() function block must be linked.

nControlMode_Write

E_MP_EV_V4_ControlMode

Control mode

nBusFailAction_Write

E_MP_EV_V4_BusFailAction

Bus failure action

nCommunicationWatchdog_Write

UINT

Communication monitoring in s (0..3600).

bSetpointSource_Write

BOOL

TRUE = bus; FALSE = analog.

nSensor1Type_Write

E_MP_EV_V4_Sensor1Type

Sensor 1 type

rVmin_Write

LREAL

Min. setpoint in % (0...Vmax). Vmin must be smaller than Vmax.

rVmax_Write

LREAL

Max. setpoint in % (25...100). Standard 100 %. Refers to Vnom and is taken into account when control mode = flow control.

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.

st_MalfunctionService

St_MP_EV_V4_MalfunctionServiceInfo

Malfunction and service information

nControlMode

E_MP_EV_V4_ControlMode

Control mode

nBusFailAction

E_MP_EV_V4_BusFailAction

Bus failure action

nCommunicationWatchdog

UINT

Communication monitoring in sec (0...3600). Not functional (reserved for future extensions).

bSetpointSource

BOOL

TRUE = bus; FALSE = analog

nSensor1Type

E_MP_EV_V4_Sensor1Type

Sensor 1 type

rVmin

 

LREAL

Min. setpoint in % (0...Vmax). Refers to Vnom and is taken into account when control mode = flow control.

rVmax

LREAL

Max. setpoint in % (25...100). Refers to Vnom and is taken into account when control mode = flow control.

rVnom

LREAL

Nominal volume flow in l/s (0...100)

arSerialNumber

ARRAY OF DWORD

Serial number of the device
