Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.
