Hi,
I am brand new to opc ua architecture.

Regarding equipement monitoring , I am used to indicate to the user some needed status informations about the machine that will help in case of some io failure.

eg for a jack moving;

Info: jack backward: waiting for sensor x.y , ouput 5.0=1

In the OPC UA world, what kind of feature is used

Hello,

for simple messages you would probably use events idicating status change. For process values you would probably use variables.
