Hello Hearbroken, I used this example (FB10)before and I recognized that it doesn't work properly. I recommend to use the Simatic AddOnModbusTCP for PN CPUs, Regards, Kaulquappe |

Hello Heartbroken, you receive error 809B from TCON (see DB1 DBW88 to DBW98). Online help: "809BThe local_device_id in the connection description does not match the CPU." You didn't parameterize the connection with the wizard. You can download the wizard here Regards, Kaulquappe |
