Read Omron CJ2M PLC using RS485 (serial ; NOT FINS)

[jagades]

Hi. I am getting a list of error messages when using Omron C-mode response. Need help on this.

Below is my flow:

Place a debug node on the output of the serial request node - What response do you see from the PLC?

This is what I see, now the buffer parser is also showing an error
