The question is more related to Siemens WinCC than with PRTG itself. I'm posting here because there is very little information available about this, and maybe someone here can help me.
I have a WinCC Runtime server collecting data from a number of PLCs around the plant. My goal is to converge the monitoring off all our systems - IT, industrial, utilities, infrastructure, manufacturing - to PRTG to ease the monitoring.
The easiest way to collect data from the PLCs is quering the SQL database where WinCC puts the data, using PRTG's SQL sensor. I successfully connected the sensor to the SQL server, but the problem is: I can't find in which tables WinCC stores the proccess data. When developing an application in WinCC the system itself builds the database and as far as I could understand the tables names aren't related to the project variables. I spent hours searching ang got nothing solid.
In time: I have zero experience on databases and SQL.
Any experiences to share?
Thanks a lot.
