Simplified control data record (V1)
For the configuration control of interface modules of the ET 200SP distributed I/O system,
you define a control data record 196 V1.0, which includes 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.
