I couldn't find any printed paper related to these tagged devices , can I send my program to you to help me in this??
-
I will try to find and told you the news.
But in the diagram that i upload in the first post there is address in the top of each remote i/o module , is that enough ?
-
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??

18 hours ago, kaare_t said: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 .
