You may use C-mode command node for this. The snip above is the PLC type and what type of task node red wants to do from the PLC. In this case, I have read the PLC data memory from Cx programmer, and able to display it to node red.

For more detailed discussion, you can look up into this :

> I have replaced with my COM 11, but the data being read is not correct. Here's my C-mode command setting: Please let me know where I'm making a mistake This is the data memory from the PLC. By right, I should be expecting the data "1122" from address number 25

It is a solved discussion on interfacing Omron CP2E Plc to Node Red using RS485
