My appologies if I am not explaining this right.
In a previous life when I used Cimplicity there was a setting in a tags logging parameters that defined an “ignore” value. When the logger encountered this value it ignored it which resulted in a null value in the database. Here is the scenario where I would find this usefull.
I have some devices that contain a value of 4000 when ‘calculating’ Other devices give me a different value. When these values are in the database it shows up on the chart and is misleading. It also has an impact when I have the chart auto scale the axis. If the database contained nulls then there would be a gap in the data and the scaling would be unaffected.
Can this be done now? Would this be a feature usefull for others?
