Dear expert,
I am developing a Ua Client using OPCFoundation/UA-.NETStandardLibrary and I want to browse the a Node from my Ua Client implementation which is a referenced with
IsOnline
reference type from OPC UA for Devices Companion Specification Release 1.01 25. July 2013
I am using following Browse node call:
session.Browse(
new RequestHeader {TimeoutHint = 10000, Timestamp = DateTime.UtcNow},
null,
nodeToBrowse,
0,
BrowseDirection.Forward,
referenceTypeId, //ReferenceTypeIds.<ReferenceType Node Ids from base OPC UA Specifications> does not include IsOnline
true,
255,
out continuationPoint,
out references
);
how can I enter the “referenceTypeId” in above browse method?
Thank you in advance for your reply,
Jayesh

Every companion specification has its own set of NodeIds. If you look into the OPC UA for Devices spec, the Annex A has URLs that specify where to find the NodeIds (and the complete information model NodeSet).
E.g. https://opcfoundation.org/UADe…..odeIds.csv – look for IsOnline.
The OPC Foundation also generates .NET files that you can use.
