Required steps
The following description shows as an example how you can create a control data record for
the configuration control in STEP 7 (TIA Portal).
To create a control data record for the configuration control, follow these steps:
1. Create a PLC data type that contains the structure of the control data record for an
ET 200AL interface module.
You can find the structure of the control data record in section Control data record for the
ET 200AL distributed I/O system (Page 55)
