Is it possible to do range convertion is 800xA History Log Configuration.
Hi,
I am reading some analog signals as percentage (1-100 %), but i need this to be converted to Level of range (0-500 meter) without changing it in the controller side and want to have History log and trend for meter range (0-500).
Thanks.

With a Property Translation aspect you can easily perform a conversion, then log the converted property.
Add a Property Extension Info aspect to expose presentation attributes (min, max, no of decimals and engineering unit) to the trend.

Hello,
we have been using this by "Property Translation aspect". That is the easiest way out.
If dont want to use that then you can change/multiply your real input value(X) with 5 i.e.5X and move into a softvariable and then you can fetch trend of the soft variable rather than physical IO.But this is a messy process..I would suggest you to go with the first one.
Pl read "Appendix A" of the link provided. It is detailed explaination of the Aspect

Also
I = input x 5
Output = i
Function block output for a new aspect you could use for logging and trends...
