Force value of OPC tag without OPC item path?

Can we force value of OPC SqlTag or use “Simulation tag address” for test purpose ?

I have lots of OPC tag with Modbus TCP devices, OPC item path is not filled because PLC adress definition are work in progress,
I would like to check template and HMI.

:scratch:

why not try something like this?

plcsimulator.org/

Yes I’ve ever test this software. very good.
It’s a good solution for Modbus, but need to fill opc item path with temporary address…

Possibility to switch tag from OPC <=> Memory would be perfect…
I’ll post a feature request…

Another solution is to create a simple simulation driver module with some Tag of each Type (boolean, int, string, …) and adress temporary these tag…

Some sort of PLC simulator would be needed to do what you want to do. I understand your need for something that would convert an OPC tag to a memory tag and then back. The problem with that would be storing the OPC Item Path somewhere. And if the PLC program is “a work in progress” then these OPC Item Paths could be changing anyways.
