Behavior after Overwriting with WAGO-I/O-CHECK ! If WAGO-I/O-CHECK is used to overwrite a parameterization made with the GSD file, the I/O module operates with the WAGO-I/O-CHECK settings until the 750-333 and 750-833 Fieldbus Couplers/Controllers are restarted. After restart, the I/O module is re-parameterized via PROFIBUS using the GSD settings. -
