OPC Server Computer Recommended Settings - Step 3
OPCENUM is responsible for providing a list of OPC Servers available on the computer where
OPCENUM is installed. That's all.
Only configure OPCENUM when you are experiencing problems when browsing the available OPC
Servers on a computer.
OPCEnum Properties: General Tab
On the General Tab, we recommend that you leave the Authentication level to NONE
We do NOT recommend that you change this setting unless you know what you are doing or are
directed to by one of our support engineers.
OPCEnum Properties: Location Tab
Make sure that the Run application on this computer
is the ONLY check box checked.
OPCEnum Properties: Security Tab
Again, our default/global DCOM security permissions (configured here) are sufficient where we can
simply specify that all 3 of the options below accept the Defaults.
OPCEnum Properties: Identity Tab
On the Identity
tab, you specify under what user account you want the OPCEnum to run under.
This is probably one of the MOST important settings for OPCEnum in some cases.
Your configuration will most likely show the "System Account" being used. If that is the case then
this is good news. It also means that OPCENUM is running as a Windows Service.
OPCEnum Properties: Endpoints Tab - No changes required on this tab.
You may now move on to configuring the OPC Client Computer DCOM settings.
