Cimplicity MB_TCPIP communication with Schneider M580

Hello,

[FONT=&quot]I have Cimplicity 9.0 (which is a v8.0 upgrade) application. I'm trying to communicate with Schneider M580 and M340 PLCs. It is working when I use Network Options Ethernet Tester tool, I can read 4xxxx registers. I would like help to find why my points aren't communicating. BTW, the 8.0 application is currently running at my client's site. I'm testing the v9.0 upgrade before commissionning it on site. I haven't changed anything in the application except upgrading it to v9.0. Thanks. [/FONT]

Can you get a wireshark trace?

What is the unit id in use?

I got it. I have to be logged in to the project for the communication to work.
