MP_EnergyValveV4_Process

MP_EnergyValveV4_Process 1:

This function block is suitable for 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. If bStart remains TRUE, the device is addressed cyclically with a period specified by the time in TMPolling. The time should be set longer than 1 second. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.

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_EV_V4_OverrideControl

Override the setpoint with defined values.

nCommand

E_MP_EV_V4_Command

Command for service and test functions of the actuator.

nDataRead

WORD

0xFFFF - read all data; bit 0 - read relative position; bit 1 - read absolute position; bit 2 - read value sensor 1; bit 3 - read analog setpoint; bit 4 - read relative volume flow rate; bit 5 - read absolute volume flow rate; bit 6 - read glycol concentration; bit 7 - read temperature1 remote; bit 8 - read temperature2 integrated; bit 9 - read temperature delta; bit 10 - read relative power; bit 11 - read absolute cooling power; bit 12 - read absolute heating power; bit 13 - total volume; bit 14 - cooling energy; bit 15 - heating energy
