Hello together,
within Node-RED I try to setup a subscription to an OPC-UA parameter. The datatype of the parameter is offered as "Extension Object".
Within UA-Expert testtool I am able to verify the object and the content of this object. There are 3 parameters defined within the object
- ID
- Name
- Description
During the test the values are filled with "ID=160" and "Name=Distanzhuelse" ... so they are not empty.
Example:
If I try to access this object using a NODE-RED flow I either choose the "Data Layer Request" of the "Data Layer Subscription".
Using the Subscription the operation fails with debug message "DL_FAILED"
Since the "ActiveTool" is the last node I can choose within the data structure I have exactly choosen this option.
If I work with READ / BROWSE Request instead, I receive an empty array as result.
But it's also not possible to access the parameters "Id", "Name" or "Description" as they are shown in UA Expert before.
Does anyone have an idea how I can access the parameters in this object or why the array is shown as "empty" even if there are currently parameters and values contained?
Thanks for your support!
