i was able to do it , i connected to each block that contain the memory i needed to read and it worked ..thank you so much for your help and your time :D
-
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 ?
-
hi ,thanks for the replay how do i do that , using cx-programmer another question please , do you recommand in other way to connect to my plc ....after i checked cj2m in that factory don't have the adapter for the modbus protocol..i am so lost .
-
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) ?

CP1W_MODTCP61_manual_en_201111.pdf https://www.myomron.com/index.php?article=1478&action=kb#ModbusTCP https://www.myomron.com/index.php?action=kb&article=1243 + i asked again the director of the factory and he said omron cj2 supports modbus tcp/ip via ethernet cable
-
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
-
i am so confused right now , can i send you the code and tell me whart i am trying to do ? cause i did implement using modbus TCP /IP ? modbusTCP.cs
-
@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 ?
-
@kaare_t oh now i get what you'r saying i will concider that, thank you so much for the answers
-
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
