Read only one element of a Boolean Array (with UPC UA)

Hello,
I communicate with a Fanuc Robot using the “OPCUA” IO Server. The driver works fine, but I would like to fetch only the second value of a Boolean Array. What syntax I should use for the address of the tag in the eWon 205. I am using UaExpert to see the content.


Thank you

It doesn’t allow you to drill down in the browser?

Have you tried adding {1} after the address?

The syntax does not work

The browser does not work well, I had to enter them manually for the other tags.

I will have to check with the Ewon team on this and let you know what the say next week.

It doesn’t look like this is possible. Can you read the whole the value and extract the bit you need using a BASIC script?
