User difined library
I've made a new function block and added to my library. At this library I'm using standards pulp and papers blocks (AIC and AOC).
My doubt is about log configuration and trend display object.
To have a correct axis configuration in the trend display, I must use those standards blocks, but I can not access those blocks into log configuration.
How do I configure the trend display to get axis limits from a value from the function block.
Thank you in advance.
System: 800xA v 4.0

Trends automatically scale RealIO variable type based property logs.
The RealIO data type in AC 800M has sub properties (.Parameters.Min, .Parameters.Max, etc.). See to that those sub properties are set correctly in controller.
If you log another data type you can add custom dynamic scaling using the Property Extension Info aspect. It can be set to read presentation from any OPC property and thus offer dynmic scaling.
Presentation attributes can be hardcoded into the Log Configuration (for each level of a log).
Last, the trend aspect itself can be hardcoded with range min/max to scale differently.
