Y10S DC 0…10 V 0 … 10 V 1000 0
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.
