I tried implementing OPC UA Pub/Sub as per the method in the link above. However, there is a difference between the device in the video above and the device I use.

Even though I set it up the same as the video, the xActice side of the reader and write boxes is not triggered to TRUE.

I also modified GlobalIP to match the IP of the device I use.

If anyone knows the cause, please help.
