OPC UA Connection configuration

Dear users,

I need to communicate between a DeltaV Project (V14.3) and a Citect project (2018 R2 Update 17) . In my Citect project I have to access some tags of the DeltaV project, a temperature measurement (Real) and a value of type UINT.

The result on display is as follows:

I can read the temperature but it is impossible to read the UINT value ?!

The result with TagDebug after several 'Read' attempts

To make sure that the OPC UA server is ok I installed another client on the Citect station to test the communication:

Communication is working properly and tags are read normally.

Can anyone help me solve this problem!
Thanks in advance

Unfortunately, your screenshots are not visible for me, and may be corrupt.

What kind of UINT are you trying to read? 16, 32, or 64 bit?

A drawback of Citect is that it does not support 64-bit variables. Please submit a post on the Ideas Forum if you think this should be added to Citect (or upvote this similar subject: https://citectscada.ideas.aha.io/ideas/SCADA-I-17).

If you are trying to read a 16-bit value, make sure to use UINT as data type in Citect.
If you are trying to read a 32-bit value, make sure to use ULONG as data type in Citect.
