Performance Equation is the frequent tool I'm utilizing for the initial calculation of raw data. Thousands of them have been employed in my PI system. Lately, I got myself lost in this familiar toolkit.
The clock scheduling is not exactly the granularity I setup. For example, for the clock schedule = 2 seconds, I got ~5 seconds for calculation performed and values updated. ( I carried out the test by accumulating a fixed value to the same point. ) Sometimes, it doesn't work at all.
A certain amount of new points created by Perfrmance Equations do not update themselves. For example, I formulate 100 Performance Equations (clock schedule=10min), while ~80 of them update themselves and other ~20 remain "pt created", when I check them out after half an hour. Those "pt created" points could remain intact a few days, and, for one moment I did not notice, they abruptly start their life in PI.
I know I got the basic settings for Performance Equation right, since most of them could work normally.
These strange things have frustrated me for the last month. Modification to the PI system I could recall are as follows,
1, 20 thousands new tags were add up to the database, while a variety of them were Performance Equationed.
2, the pipeschd.bat was expanded for a few new clock schedules.
Could you please help me out?
Thanks in advance!
