Freelance OPC Server Limit Points
I'm trying to connect S+ Operation with Freelance OPC Server, with 1500 Tags (20000 atoms), and shows only 4500 Signals (300 Tags) in Good Quality and the rest in Channel Failure.
I don't know if i need to create more OPC Server instances or do an special configuration.
This happens with S+ Operation or any 3rd-Party Opc Client.
You can find the limits in the Freelance 2016 Engineering Manual OPC Server F.
There is a limit of signals per controller in an OPC gateway of about 2500 REALs (or whatever fits into 10x1400 bytes), and a limit of OPC-Gateways accessing one controller of 10. You can limit the access of an OPC Gateways to certain controllers. The signal limit limits the simultaneously used (by clients) signals, not the configured signals.
You can find statistics entries for the OPC server in the Windows Performance monitor. See section "Performance Monitor for OPC server" in the manual.
After the Board has dropped my first answer to this question, i try to repeat it.
You can change the maximum of connected atoms by changing one setting in registry:
HKEY_LOCAL_MACHINE/Software/(Wow6432Node)/Hartmann & Braun/Freelance/OPCServer/MaxVarlist
The default value is 10, the maximum value is 100. Increasing this value leads to lower performance.
