Hello @DM, 

I am trying to receive some values to ControlBuild through OPC UA driver. The Server and Client. I have noticed some abnormal behavior from the 20x  OPC UA drivers.

• 20x OPC UA Driver works quite robustly. However, some variables are not communicated properly even if the declaration and configuration of variable is exactly same​​​​​​​. In the attached image I received values from the same OPC Client. As shown in the image below, UA Expert receives correct values for the marked variables while OPC UA driver from ControlBuild 20x does not receive proper value.
• Furthermore, please note the .S file of the project describes two variables exactly the same way, however, one of the variable (DRILL_STATE) is interpreted correctly while the another (CLAMP_STATUS) did not
• Additionally, I have noticed that under slightly strained conditions, the OPC UA driver in 20x terminates randomly without any errors or messages. Is there any remedy to this problem?

Could you please inform me if you have already come across this issue before? It would be really helpful for my project to solve this issue. Any help, questions and feedback is appreciated.

With best regards,

Nihar Shah
