Lock Timeout in Advant Master Connectivity
The Advant Master Connectivity in 800xA doesn't use the Standard Lock Server. Instead the "selected" flag from the controller is used.
In the documentation is said "the lock is released...after a specific time out period". This is normal 5 minutes. Is it possible to change this time out?

Without being 100% certain, the MB300 OPC Server will attempt to "deselect" (release lock) shortly before the object handler in the controller times out after what I believe 5 minutes.
So even if the OPC server allowed to tweak the timeout, the lock would anyhow be lost when the controller times out.
