Timeouts happen about once or twice per day, and generally for all, or the majority, of the OPC checks in a folder (we currently only have 16 check s - 8 in each of two folders). Clears on the next run (15mins) generally. I have just set a retest and then shorten the test time until a good response is received.
This is fine as levels we are reading are not critical - and its quite possible its the server causing the problem as we have not been using it long.
Basically we just put the opccheck exe in the temp folder of a machine and ran the below comand:
R:\>"C:\temp\opccheck" -serverid:AutomationDirect.KEPDirectServer -host:{IP Address} -user:{username} -password:{password} -itemname:"NIX-41-INK.Line-A.InkLevel.Black-B"
We then get
ScriptRes:Unknown:OPCDiscover Error: Interface not supported
This exact same command works ok from the Hostmon machine that has had OPC Core Agents installed (and to do this it required .NET 2 or greater)
Got core components (OPC Core Components 3.00 Redistributable (x64)
) from
http://www.opcfoundation.org/Downloads. ... KEY&CI=286
but it was only from remote machines that we had problems so maybe it was just the proxy stub we needed.......
