Resetting to factory settings

The following options are available to reset the COM190 communications module to
factory settings:
• Function button S1
• PROFINET standard functions
Note
By resetting to the factory settings, all communication parameters and security settings
are reset. The COM190 communications module must then be re-parameterized in the
same way as for first commissioning.
