Browse OPC DA Items - Error Syntax doesn't conform to the server
Posted: 12 Oct 2021, 20:10
Hello,
I am using a UA Gatway OPC UA Server to a UA Gateway OPCUA to OPCDA configuration to obtain data directly from T3000 communications modules (OPC UA). The UA Gateway's DA server is the connection to which my PI OPC DA client connects. We have some minor issues.. But when I try to manually load items (URLs) the DA Server on my side of the firewall ... I can view the items. However, when I need to browse a significant number of items, say 300+ or 500+ ... using Matrikon OPC Explorer ... when I go to add them, it tells me the items syntax doesn't conform to the server ... but if I take those same itemIDs (URLs) and add them a few at a time, almost all of them work.
Sometimes just I want to browse all 3300 tags to verify everything is working ... in that case I get at most 15 or maybe 20 items working. All the rest fail validation because of this syntax issue. But again, if I chop it up into small enough blocks, I can browse almost all 3000 of the tags.
The error code is 0xc0040008
Thanks,
Bubba
