TX1200 32 Version: 1.1
This function block is used to configure the Energy Valve actuators EV..R2+... (V4). 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. bError is
used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId .

bStart : BOOL;
bRead_Write : BOOL;
strDataKL6771 : DataKL6771;
rVmax_Write : LREAL := 100;
rVmin_Write : LREAL;
bSetpointSource_Write : BOOL := TRUE;
nSensor1Type_Write : E_MP_VRU_Sensor1Type;

rSetpointAbsFlowDeltaT_Write : LREAL;
bSelectMeterRegister_Write : BOOL;
MP_Address: MP-Bus address of the slave.
bStart: a positive edge starts the function block.
bRead_Write: if FALSE then READ only; if TRUE then READ and WRITE.
strDataKL6771: the data structure with which the KL6771 [
}
25] function block must be linked (see
DataKL6771 [
}
72] ).
rVmax_Write: max setpoint in % (25...100). Standard 100 %. Refers to Vnom and is taken into account
when control mode = flow control.
rVmin_Write: min setpoint in % (0...Vmax). Vmin must be smaller than Vmax.
bSetpointSource_Write: TRUE = bus; FALSE = analog.
nSensor1Type_Write: sensor 1 type (see E_MP_VRU_Sensor1Type [
}
69] ).
nControlMode_Write: control mode (see E_MP_EV_V4_ControlMode [ } 66] ).
rBusFailPosition_Write: bus fail position in % (0...100). Not functional (reserved for future extensions).
nCommunicationWatchdog_Write: communication watchdog in s (0...3600). Not functional (reserved for
future extensions).
rPmax_Write: 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 (see
E_MP_EV_V4_DeltaTLimitation [
}
66] ).
rSetpointDeltaT_Write: 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: 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: FALSE = certified meter; TRUE = lifetime meter.
