Diagnostics with PROFIsafe connection

The CS..A safety option with PROFIsafe connection triggers a diagnostic alarm on the F-PLC in the data exchange between the F-PLC (fieldbus host) and the safety option (fieldbus device) in case of an error. Simultaneously, the associated error code is transferred via the communication connection.

The F-PLC responds to the issued diagnostic alarm if the Diagnostic alarm assembly parameter is enabled for the safety option in the F-PLC per configuration. Depending on the fieldbus used (PROFINET), the error code of the safety option can be evaluated in the F-PLC. A diagnostic alarm does not trigger an error response in the F-PLC (default setting of the safety option in the F-PLC).

The safety option has PROFIsafe and assembly-specific error codes. All error codes of the CS..A safety option are listed in an error table.

INFORMATION

You can find the structure and the evaluation of a diagnostic data set in the F-PLC in the respective manual of the fieldbus host. In addition, ensure that the current device description file of the SEW‑EURODRIVE drive system is always installed in the engineering tool of the F-PLC during configuration.
