End code unknown

3 posts in this topic


I have problems when  trying to communicate with my cj1m.

Recently, i have added an ETN11 ethernet module and i can now communicate with the PLC using CX-programer. But the problem is i cant communicate with my python script to read something.


I just want to read CIO area 2 from bit 0 to bit 15. But Wireshark tells me that the end code is differente than completed. I cant find anywhere the end code 9005, any ideas?

Thanks @gclshortt for your answer, I didnt know this omron library, i will give it a try.

Anyway i could find the solution. I have changed the node number in the command to 00 and it works, it seems like IP layer covers these section and no need to specify it in the FINS command.
