Hello,
I want to display and monitor vaules of arrays in the Data Access View. In my case I am connected to an Siemens OPC UA Server and I want to read DBs.
When I use the method "readVar" with the argument /Plc/DB13.DBX34.1 for example, it works.
Is it possible to show the value of this DBX34.1 also in the Data Access View?
When I create a custom node "/Plc/DB13.DBX34.1" it returns
Item [NS2|String|/Plc/DB13.DBX34.1] failed [ret = BadNodeIdInvalid]
The Node has following attributes:
Invalid Datatype: Expected OpcUaType_NodeId, Received OpcUaType_Null

Re: Display Arrays in Data Access View
Hello Tzowbiie,
it depends on the server how NodeIds are formed. In this case, please contact the server vendor for information on how to directly address data of the PLC. It might be necessary to put quotation marks around the string of the string NodeId.
