PPS2 interface
Transfer of an analog control command to a room unit connected via the PPS2 interface. Only Object 195
(= Room temperature display) can be used in the analog output block. As the value is already available as a
converted or referenced value, no conversion is required, that is, [Slpe] must be defined as 1 and [Icpt] as
0.
Line resistance with [Icpt]
For analog inputs (measurement of temperatures or resistances), most signal types are calibrated at a line
resistance of 1 Ohm. The [Icpt] can be changed at the AI block if the line resistance deviates strongly from
1 Ohm.
