Please note that a dialog-based configuration of S20-AI* /AO* and other adjustable peripherie may not be supported yet.
Meanwhile PDI objects provided by the S20-EC-BK cover this service.

The usage of the 'PDI Write Tunnel' is pointed out below ... the attributes channel1,2,3 input-range is written examplarily,
.... adapt the write service to the belongings needed.

  1. configure ctrlX-IO-ENG with S20-EC-BK and connected IO-peripherie. 
  2. get familiar with the desired channel setup depending on the the modules connected (S20-Ax-yyy),
    S20-AI4-U configured below - the setup is represented by object 0x80 - consult the appropreate datasheet(s).
  3. add a new PDI write tunnel :
      object-index16#2000 is related to 1st module added to S20-EC-BK,
      adapt index depending on the module-position,
     object-subindex 16#01 commands to write (take care that the subindex of the object does not differ).

  4. enter the data-stream bytewise in dezimal/hex regarding the adjustments and focus on . (Object 0x80 Subindex:__ etc. )
