Is it possible to do range convertion is 800xA History Log Configuration.
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).
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
