–
In order to determine what type of parameterization error has occurred, use the
corresponding software to access the controller online and read the error.
Proceed as follows, e.g., in the VersaSafe system:
•
The diagnostic LEDs indicate that an error has occurred.
•
Access the higher-level standard control system online.
For each module of the VersaSafe island, a diagnostic register is mapped to the
process image of the IC220SDL963.
From this, determine the module of the safety island in which an error has occurred.
•
Evaluate the specified diagnostic code.
