Wonderware Cannot Access Topic problem

[jack.large]

Wonderware 7.0
CTIos 5.2 Running as a service. Suitelink also running as a service
Windows XP.

I keep getting the Wonderware Cannot Access Topic error.

I have verified that the topic names in CTI and Wonderware are the same.

I can ping on the PLC that I am trying to access.

Using the CTI Diagnostics tool, I can see the PLC.

However it appears that Wonderware and CTI are not communicating.

I had something like this in the past and when I open CTI, I has to right click and select " run as"administrator. It seem to be some type of privileges problem. I also seem to remember that I was unable to run it as a service. Once I put it in service mode it was a pain to get it out of this mode. I had to go on CTI's website and get the information on how to stop it. It's been a few years and my memory isn't that great.

Kev,

Thanks for the reply. Unfortunately that did not solve my problem. Going to keep looking.

have you tried reading data from the IO server using WWClient?
