Setting up a PI UDS

67 Views

I am trying to set up a UDS server to access a PI data historian at one of our manufacturing plants and have a few questions.

1. Can the UDS server be the same server we have xMII installed on?

2. Does any UDS software need to be installed on the PI data historian server?

I first tried to install the UDS Framework (2.5.0.4) on our xMII development server (a Windows 2003 x64 box) but I was having issues with the system32 vs. sysWOW64 folders. I edited the registry to point the UDS service to 'C:\WINDOWS\SYSWOW64\LUDS.EXE' but starting the service failed with an 'Invalid class string' message. Thinking it was a x64 issue, I installed the framework and PI UDS on my Windows XP client but I'm still getting the same ''Invalid class string' message. Using the LUDSAPPS.EXE approach had the same results on my WinXP client.

Browsing through other forum posts, I found one regarding INTOUCH that indicated some software was needed on the data server itself.

Any help would be appreciated.
