Appendix - Notes of Using OPC/DCOM
1. When the Installation of PCIS-OPC is successful, the NuDAQ
PCI OPC server has been registered in system registry. Or you
can register it manually by executing the command “NQOPCSvr
-RegServer” in DOS Prompt.
2. Because the OPC server is based on the COM/DOCM of
Microsoft, your Windows system must support DCOM capability.
3. DCOM is a standard part of the Windows NT 4.0 distribution.
You preferably have applied the latest Service Pack for Windows
NT 4.0 (above Service Pack 2).
4. DCOM is a standard part of the Windows 98/2000 distribution.
5. You must make sure the setting of the following registry keys.
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLE\EnableRemoteConnect = ‘Y’
\HKEY_LOCAL_MACHINE\SOFTWARE\Microdoft\OLE\EnableDCOM = ‘Y’
6. The “client” machine would do the same configuration above.
You must log on with the same user ID as on the “server”
machine.
