Diagnostics and Troubleshooting

Obtaining Diagnostics and Status Information

Diagnostics information and status information on the safety module eSM is provided by the drive. Refer to the user guide of the drive (Related Documents) for additional information.

The states of the inputs and the outputs as well as the operating states of the eSM safety modules can be read via the fieldbus. The parameters are accessed in the same way as the parameters of the drive.

NOTE: Reading a status message via the fieldbus may be subject to a time delay due to the asynchronous access to the parameters of a safety module eSM.

The menu item "Status" in the commissioning software allows you to display the status of the safety module eSM.
