Problem viewing Graph Measurement

Feb 22, 2013 at 2:50 PM
Hi I'm a new user of open pdc. In my lab I set up two SEL synchrophasors (SEL-421) and one SEL 3378. We successfully ran the pmu connection tester and saved the necessary connection and configuration file. I configured node, historian, input wizard following the steps as mentioned in the documentation. I could initially see the graph measurements. But I cannot see them anymore. I did not change any major settings though. Whenever I click the "Graph Measurement" option, the dots associated with my devices turns green and red alternately.

However I can see graph measurement using the Synchrwave software.

What is wrong with my settings? I urgently need to get it fixed!! Thanks a lot.

Hello Mgttu,

Sounds like the devices might be having connectivity issues. Do you have any messages in the ErrorLog.txt file in the openPDC installation directory?

Thanks,
Stephen

Hi thanks a lot for reply Stephen!
I checked the error log. It says
(for outer exception)

Exception Type: System.Exception
Exception Message: Data channel receive exception: The I/O operation has been aborted because of either a thread exit or an application request

(for Inner Exception)

Exception Message: The I/O operation has been aborted because of either a thread exit or an application request
Exception Target Site: ProcessReceive

What is the issue now? How to make it work?

Thanks!

That error message is common during shutdown sequences or when a socket is being disposed. It sometimes occurs during startup as well, but it doesn't necessarily indicate connectivity issues, and often the system will run fine in spite of it. Is that the only error you see in the log? The most recent errors will appear at the end of the log file.

Thanks,
Stephen

Can you post the connection string for your device?
