WinCC OA Logs - Warning 54 meaning

[Natty]

Hello,

Do you know what this warning means ? I am trying to set up several Modbus Master request (Holding Registers) to an M580 Schneider PLC.

Thanks in advance.

Can you please post the complete content of the log message.
The error code "54" is the common error code for "Unexpected state" in WinCC OA and is used in several log messages.
