MP_JR_Actuator_Process

MP_JR_Actuator_Process 1:

This function block is suitable for 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

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.

strDataKL6771

DataKL6771

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

TMpolling

TIME

The time for which the function block should address the actuator. Default 10 s, minimum time 1 s.

rSetpoint

LREAL

Setpoint in % (0...100).

nOverrideControl

E_MP_JR_V4_OverrideControl

Override the setpoint with defined values.

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.

strMP_Serial_Number

MP_Serial_Number

Structure for the serial number.

rSetpoint_Read

LREAL

Setpoint in % (0...100).

nOverrideControl_Read

E_MP_JR_V4_OverrideControl

Overridden setpoint.

rRelativePosition

LREAL

Relative position in % (0...100).

rAbsolutePosition

LREAL

Absolute position in ° (0...96).

nSensor1Value

DINT

Sensor 1 Value in mV/ohm (0...5500000).

nSensor2Value

DINT

Sensor 2 Value in mV/ohm (0...5500000).

rSensor1Temp

LREAL

Sensor 1 Temperature in °C.

rSensor2Temp

LREAL

Sensor 2 Temperature in °C.

st_MalfunctionService

ST_MP_JR_MalfunctionServiceInfo

Malfunction and service information.
