10.2 Creating the control data record
Control data record
For the configuration control of an ET 200SP CPU, you define a control data record 196
V2.0, which includes a slot assignment. The maximum slot of the configuration corresponds
to the slot of the server module or last slot of an 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.
