  1. Hi,

    We are receiving an error "*Error** PLC of all MODBUS/TCP connection modules Port No. is mismatched. When using multiple MODBUS/TCP connection modules, PLC of all MODBUS/TCP connection modules Port No. must be matched.   MODBUS/TCP Connection Module  NV_E02435" while trying to add two slave connections with different port numbers.....Please clarify on this error...


  2. Hi Gambit, I tried to do the same code to reset the module RJ71EN71. But received the attached error. The module number indicated in the PLC is 0060. So I used 006, which is indicated as 6. Please help me on this error.

  3. Hi Gambit,

    Thanks for the response. We we face an error in the Modbus comms, it stops working and requires a power cycle or remote reset from the GX Works. So, looking for a method to reset the Modbus comms in the RJ71EN71 ethernet module.

     


  4. Right..the string is a variable. The string comes from the NB-HMI. There are no rules for the string format. It could be "174Mesh" or "Mesh174" . I want to extract the numbers and use it for further processing. In my initial request, i mentioned as "digits" instead of "numbers", by mistake. I apologize for that.
