Indirect access of nodes
Posted: 10 Jul 2014, 11:16
Hi,
I have a question for the UA possbility. There are two ObjectTypes created in the same namespace: ObjectTypeA and ObjectTypeB. ObjectTypeA have a method component: MethodA and a variable component: VariableA. ObjectTypeB have a variable component :VariableB. VariableB is a data source of VariableA.
In this condition, UA client can access the value of VariableA by calling the MethodA with addressing informations of VariableB as input parameter, where MethodA reads value of VariableB then writes to VariableA. Current UA has such a capability?
If yes, the extension questions are : 1, how about MethodA subscribe the values of VariableB? 2, how about ObjectA and ObjectB are in different namespaces?
Thanks!
