I am intending to use Modbus RTU with RS-485 to connect my C-More panel to my Telemecanique PL7 PLC. I am getting error codes no matter how I physically connect my PLC or ModSim, whether I use RS-485 or RS-232, and no matter what baud rate, parity, or stop bit setting is applied. The variables are all being transmitted just fine. I already have the newest updates to the software. I am getting error 0x0002 with my Telemecanique Twido PLC and ModSim (via both RS-232 and RS-485). I am getting error 0x0003 with my Telemecanique PL7-07 PLC, PL7 PLC, and Siemens RWF40 boiler control. I am getting error 0x0001 with my Honeywell burner control. The only connected device that did not show an error was my A/D DL05 PLC. Again, the data is all being transmitted but this error will not go away. I have checked the connections, made sure they are the right type of cable and all that, and tried to change every setting possible. I also searched the forums and couldn't find anything on this topic.
