rTemperature1_Remote:

temperature1 remote in °C (-20...12). A value of -1 means that the data is

disabled (see VAR_INPUT nDataRead.7 = TRUE).

rTemperature2_Integrated:

temperature2 integrated in °C (-20...12). A value of -1 means that the data is

disabled (see VAR_INPUT nDataRead.8 = TRUE).

rDeltaTemperature:

temperature delta in K (0...14). A value of -1 means that the data is disabled (see

VAR_INPUT nDataRead.9 = TRUE).

rRelativePower:

relative power in % (0...100). A value of -1 means that the data is disabled (see

VAR_INPUT nDataRead.10 = TRUE).

rAbsoluteCoolingPower:

absolute cooling power in kW (0...21.5). A value of -1 means that the data is

disabled (see VAR_INPUT nDataRead.11 = TRUE).

rAbsoluteHeatingPower:

absolute heating power in kW (0...21.5). A value of -1 means that the data is

disabled (see VAR_INPUT nDataRead.12 = TRUE).

rTotalVolume:

total volume in m³ (0...214748.36). A value of -1 means that the data is disabled (see

VAR_INPUT nDataRead.13 = TRUE).

nCoolingEnergy:

cooling energy in kWh (0...21474836). A value of -1 means that the data is disabled (see

VAR_INPUT nDataRead.14 = TRUE).

nHeatingEnergy:

heating energy in kWh (0...21474836). A value of -1 means that the data is disabled (see

VAR_INPUT nDataRead.15 = TRUE).

MP_EPIV

This function block is used to control a pressure-independent control ball valve. For more information please
visit

www.belimo.ch

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 s.

bError

is used to indicate an error in communication with the actuator. The

type of the error can be read with

iErrorId

VAR_INPUT
