390186, 

Can you try a lower baud rate,  I have included a link to some troubleshooting tips to see if you can find a missing link.

hello,
I was able to communicate with the module ex-rc1 when it is disconnected expansion modules, with both usb and rs 232 (or even downloading done on it) the problem is when I connect the modules (2 IO-DI16, IO-5 ATC8).
While OPLC with its port I / O Expansions communicates with EX-A2X (2 IO-1 and IO-RO16 AO6X)
The problem is on the modules unfortunately the old ex-rc1 and the old V570 gone are the short circuit, very likely connected modules on the ex-rc1 even if the LED flashes will no longer be able to communicate with the new ex-rc1.

Now we are providing for the replacement of 2 modules IO-DI16 and 5 modules IO-ATC8

I also tried to connect the module IO AO6X to ex-rc1 without configuring
and are unable to communicate via usb rs232

When I installed the new modules will give you results of the operation

thanks
