rSensTemp: Sensor temperature in °C or °F.
rDewPointTemp: Temperature of the calculated dew point in °C or °F.
rHumid: Humidity in percent (% 0.01).
uiCo2: CO2 content in ppm.
stUnit: C = °C or F = °F, ? = not read.
bDigitalInput: DI sensor read if bReadDISensor is TRUE.
bSensorError: One of the sensors has an error.
st_SensorType: Sensor type '?' = not read / type / 'unknown' = number unknown.
6.2.15 MP_RoomSensor_Parameter
This function block is used for parameterization of room sensors. Further information can be found at
www.belimo.ch .
MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bRead
reads the parameters, bWrite writes them to the room sensor. bBusy indicates that the block is active.
bError is used to indicate an error in communication with the drive. The type of the error can be read with
iErrorId .
