Retrieve data in OPC UA Notifier Event

[daniel_rudaz]

Hi,

We try to connect on "EXTERNAL" opc ua server (like injection press, data acquisition systems, ..) that generate custom notifiers.

The weakness on OPC UA toolkit is that it is a closed environment.

I am able to connect the toolkit on the notifier and catch the event with actual tool, but all data of the event (plots, values, ...) are unreachable (UA expert show them).

A very simple Python code is able to retrieve these data, but there are out of the labview environment, and as it has to create a thread on the notifier, I am unable to run such structure through the Python tools in LabView.

Some example:

A shortcut of ENGEL structure

Event registration need filtering, ENGEL

Event registration need filtering, Kistler COMO Neo

Data in each event, Kistler COMO Neo

Thanks in advance.
