Using node red for clp memory

Good morning friends, I'm wanting to build an application using node-red, as a master of an already installed clp. I wanted to be able to read the memory of the clp without touching the clp, does anyone know if this is possible, and how?

Welcome to the forum!

Could you please tell us what "clp" is in your case.

Hi Ghayne, I'm from Brazil, here CLP is the same as PLC, sorry for the mistake

You will have to look at the manuals for the plc to see what it provides. Many allow the use of modbus for access.

Depends on the PLC and how it is configured. What is the make and model? What communication protocols are available built-in and via add on cards?
