bBusy: this bit is set for as long as the function block is active.
bError: the output becomes TRUE as soon as an error occurs. This error is described via the iErrorId
variable.
iErrorId: this output outputs an error code in the event of an error (see MP_ERROR [
}
70] ). bError goes
TRUE at the same time.
st_MalfunctionService: malfunction and service information (see St_MP_EV_V4_MalfunctionServiceInfo
[
}
73] ).
nControlMode: control mode (see E_MP_EV_V4_ControlMode [ } 66] ).
rBusFailPosition: bus failure position in % (0...100). Not functional (reserved for future extensions).
nCommunicationWatchdog: communication watchdog in sec (0...3600). Not functional (reserved for future
extensions).
bSetpointSource: TRUE = bus; FALSE = analog.
nSensor1Type: sensor 1 type (see E_MP_VRU_Sensor1Type [ } 69] ).
rVmin: min setpoint in % (0...Vmax). Refers to Vnom and is taken into account when control mode = flow
control.
rVmax: max setpoint in % (25...100). Refers to Vnom and is taken into account when control mode = flow
control.
rVnom: nominal volume flow rate in l/s (0...100).
rPnom: nominal output in kW (0...21.5).
rPmax: max setpoint in % (5...100). Refers to Pnom and is taken into account if control mode = power
control.
nDeltaTLimitation: specifies whether the device responds to a low delta T (see
E_MP_EV_V4_DeltaTLimitation [
}
66] ).
nDeltaTManagerStatus: indicates the status of the DeltaT Manager (see E_MP_EV_V4_DeltaTManagerStatus
[
}
67] ).
rSetpointDeltaT: setpoint DeltaT in K (0...60). Is taken into account if DeltaT limitation is active (not
disabled).
rSetpointAbsFlowDeltaT: setpoint Abs flow DeltaT in l/s (0...100.000). Considered when DeltaT limitation is
set to DeltaT Manager scaled.
arSerialNumber: serial number of the device.
bSelectMeterRegister: FALSE = certified meter; TRUE = lifetime meter.
