Hello,
I use the NI OPC UA Client Toolkit with LabVIEW 2018. A customer has about 50 pressure sensors. I want to collect the data from them via UPC UA Client. This works fine, but only for 28 OPC UA connections. Then it fails. The Error code is: -356629 (An operating system resource is not available). When I start another exe on the same PC, which uses also the OPC UA Client, this exe can get data from another UPC UA Server.
There is an Problem documentet for the NI OPC UA Server with the same Error number. There it can not be more than 25 Clients (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000fy6kSAA&l=de-DE). And it should be fixed with an update to LabVIEW 2019.
Will it be the same with the OPC UA Client Toolkit? How many connections are possible with the 2019 Version? 50 would not be enough.
Thank you for your help.
