I'm using Intouch wonderware in a really simple application. We need to monitore some variables that are given by a Flow Computer OMNI. I use Topserver to connect with wonderware in order to read the values from the flow computer.
We also use historical trend and 16pen trend.
In addition we needed to made a report of the hourly average value from each variable in the last 24 hour. There are two kinds of reports one from Oil variables and one for Gas variables. In order to report the historical values I used de HistData to export the lgh files frome to CSV, and then using macros print the report. This solution worked fine for a couple months, we asked support from Invensys and they told us that the solution using Histdata works with DDE and we are using windows 7.
After that we adquire Hisotorian becaus Invensys said it would be the solution, and it worked for a month to fail again.
Can someone help me?
