Using OPC UA server plug-in

Hi everyone, I wonder if anyone of you have tried using the OPC UA server plug-in. I will have the link here for people who wants to try too: VC2OPCUA: Visual Components OPC-UA plugin

So the thing the last version being pushed from these brilliant guys only support till 4.1. However I tried with 4.2 version and it would still works fine, I can see and modify parameters. However when it comes to Visual Component’s conveyor, whenever I tried to make changes to it dimensions on UaExpert, it would crash VC altogether, but on other components like vacuum gripper modifying parameters is completely fine. So I wonder if anyone has the same problem?

Also I think it is super duper cool if VC can consider support OPC UA server instead of using it only as a client as now.
