  1. After i put these parameter no error appear on the plc screen and its in run mode and the command for these plc input or output is working.

    But for remote i/o no responding of the commands .

    And for plc n01 it has already its program without me - I didn't program it- .ijust rewrite n01 program.

    Note : when i remove coxial cable no error appear on both plc , also when i remove twisted pair no error appear too.

    There are 4 analog outputs should give number of tension strenght for the machine and it comes from remote i/o , it show me 0 . I think there is somthing wrong for the addresses in network of these  i/o module , where i should put there address??

    We need screenshots from the network parameter setup you have in GX Developer... It's a bit hard to help out without knowing what config you have downloaded to the PLC.

    As a side note; you do realize that you are rewriting the code to a CPU that has been out of production and spare parts for years...??

    now i put this parameter, the error " link par. error" is gone but still no responding for start button of  remote i/o module.

    because i don't know where i should put the addresses of remote i/o modules .

  3. I have a A3A cpu plc master and local connecting through coxial cable ,

    these two plcs exist in printing machine and the master one had lost his program , i found a program written on papers so I rewrite it using gx devoloper.

    now i face a problem with network parameter , beacuse the master unit is also connecting to 6 remote i/o module through twisted pair cable .

    i will upload the diagram of the newtork for both plcs and with the remote i/o unit .

    and when i upload the program with out parameter it give me an alarm in plc link par. error

    please help.
