Comms issue between SCADA and Historian

2 posts in this topic

Hi all,
New to this forum.
I am having an issue on one of our customers sites where the InTouch SCADA node and Historian lost connection.
As a result the operators could not see any alarms or trends.

From looking at the SMC log files on the SCADA node an event occured at midnight 00:00.
The message reads "HistoryProducer: Failed Creation of rollover log file.."
Due to this the alarm manager could not connect to the Historian database for alarms.
Message "Attempting to Connect to Provider '\\ServerName:\intouch'"

Hence why the operators could not see any alarms or trending on the system.

Has anyone seen this behavior before ?

I assume this is Wonderware InTouch SCADA and Wonderware Historian?  Sounds like the issue is not being able to create the log file.  I would be looking for things like hard-drive space and read/write permissions to the log file location.  I don't have much experience with InTouch SCADA but is there an option to create all log files on startup?  Citect SCADA has something like this and would avoid these issues (or at least you would know about them on start up).
