bSetpointSourcesRead : BOOL;
bOperationModeRead : BOOL;
nSensor1TypeRead : E_MP_VRU_Sensor1Type;
nApplication : E_MP_VRU_Application;
bControlMode : BOOL;
nRoomPressureCascade : E_MP_VRU_RoomPressureCascade;
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.
rNominalVolumeticFlow: nominal volume flow in m³/h (0...60.000).
rNominalDeltaPressure: nominal differential pressure in Pa (0...10.000).
rMinRead: min in % (0... rMax ). rMin must be smaller than rMax .
rMaxRead: max in % (20...100 %).
bSetpointSourcesRead: TRUE = bus; FALSE = analog
bOperationModeRead: TRUE = overpressure; FALSE = negative pressure
nSensor1TypeRead: sensor 1 type [
}
69] .
nApplication: visualization of the application [
}
67] selected by the manufacturer.
bControlMode: visualization of the control function selected by the manufacturer. TRUE = volume flow rate
control; FALSE = position control
nRoomPressureCascade: room pressure Cascade control [
}
68] .
