Hello I am following this post to setup RS485 connection between IOT2050 FS:05 (image V1.3.1) and PC. https://github.com/SIMATICmeetsLinux/IOT2050-Serial-ModbusRTU-Example I connected to the IOT pin 1: +, 2: -; in my RS485 to RS232 converter, the converter is connected to my RS232/USB converter. I used, in the nodered, the program of the post (I attach image) When I use that the nodered sends data to the PC which is the client. On the PC I have the Modbus Poll software, I have everything configured the same (115200, 8, none, 1) the Modbus Poll always gives me a Timeout error, but when I do an injection on the nodered node it gives me a CRC error. If I set the PC to send data and the IOT to collect, no error, but it does not retrieve any data either. I don't know what to look for, does anyone have any ideas? Thanks, Edu
