But the modbus communication works as well without a valid license number. A090 doesn't set the ERROR-Bit. The error bit is set only, if the errorcode is unlike A090. If the errorbit is TRUE (randomly or not), you should check what the errocode on STATUS_MODBUS or STATUS_CONN is. Wüstenräuber

So the problem with OB100 is sorted I think as the code is going to the second network as my second ID connection works well. First connection: ID = 1 IDB: DB103 DB_PARAM: DB2 control dat 2: DB4 So now I am still left with the problem of getting two connections working. Initially only connection ID 1 worked, now itsonly connection ID 2 that works.
