Representation of the Measured Values in the
Process Image (PI)
The I/O module records and calculates numerous measured values. Up to 3
measured values can be represented in the process image (PI). The selection of
these ones is made with the process data indices in control bytes C0, C1 and C2 in
the output data.
The following table lists the available measured values:
