PM554-T-ETH - Invalid configuration data isuse

Hi,

I'm trying do some tests with PM554-T-ETH PLC but even I try to use Multi online change tool or download new program from CoDeSys I always get the same E3 errors:

- Invalid configuration data

- Invalid configuration of Onboard I/O module

- Invalid configuration

- Project contains invalid configuration data

It seems that the PLC can't get/contain any configuration from PS501. For example, I configured COM1 to Modbus, but in CoDeSys PLC Browser command "com settings" shows: Protocol - Online and Config - not avail.

Please, ask for more information if needed.

Thank you for suport
