     i used it :D i mean the FINS  protocol and it worked , i connected to the main  , using port 9600. 

    i just have a question : the fact that i connected to the main with FINS ?can i read memory area that is located lik in sub programm ? ( i have no experience in plc ) 

    when i open cx-programmer i have the main and other programms do u see what i mean ? can i read a memory that it's located in other feeder for exemple ?

    i have this code in c# in order to communicate to cj2m using etheret cable , but i get a connection error ( u can't reach : 192.168.250.1 :9600 )

    is there any configuration that need to be done on the plc ? i mean i don't quite get (the node and all thoese properties i fnd on cx-programmer) ?

    oh , no i get that , i was wondering about what exactly the diffrence , i looked in google  , but for  omron cj2m (i've checked it in their documentation )  they do support modbus tcp/ip via ethernet cable

    @Crossbow please excuse my ignorance  first isn't modbus tcp/ip  and using ethernet cable  is considered as modbus ethernet ?  i mean using c# i coded using the modbustcp.dll ? and please would you do me a favor and give me the link to that post ?

    hi , i am sorry i didn't quit catch the meaning of  ( configure something in the plc ? )

    i thought that was a direct communication : imean code the connexion function , insert the plc's IP @ and the port  and using the ethernet cable ..voilà ?

    Hi 
    i am trying to connect to omron plc (cj2m ) from my pc  using modbus tcp/ip in c# , by using the port 502 i  get an error saying that the port can't be reached

    is there any method to fix that or change the port number ?

     

    thank you

    the plc is the client , my code is the master ..my goal is to be able to read from my plc ( a basic scada/him application ) 

    -yes , it supports the tcp/ip.

    thanks for the beside note , just because it was said that for modbus tcp/ip communication goes throw 502  ...i just don't know where the plc keep telling me (the port can't be reached ) , i even tried others (random ) and can't be reached also 

     

     

    thanks a lot
