Control data record (V2)
If you change the potential groups in the station option compared to the station master,
define a control data record 196 V2.0 for the ET 200SP interface module which contains a
slot assignment. The maximum slot of the configuration corresponds to the slot of the server
module or ET 200AL I/O module (in a mixed ET 200SP / ET 200AL configuration).
The table below shows the structure of a control data record with explanations of the
individual elements.
