Thank you for your fast reply. Is it possible to change “MaxSessionCount” in the config file? Regards Martin

There is currently no way to change this value through PLCnext Engineer, but it is possible to directly edit the configuration file on the PLC. However, we always recommend against making changes to system files on the PLC.
