Write a Variable node with Current Read accessLevel

[RafaelCrespi]

Hi,

I have a Variable node with accessLevel=Current Read for access via UaExpert. Now I need to modify the Value Attribute with the
internalSession of the OpcServer. How can I do it without changing the accessLevel for UaExpert?

Thanks a lot,

Hello Rafa,

you can't do that using the internalSession because the internal session is doing all the validation and access checks that are also done for service calls coming from a client.

Solution 1:
You configure the NodeAccessInfo on that specific node to only grant write access for a special user and assign that role to the internal session.

Solution 2:
Don't use ServerManager::Write but instead access the Node directly using setValue() for example.
