I know that memory tags value or quality change scripts has access to previous and current values and also gateway event scripts as well.
I want to know if project library scripts has access to previous and current values. My script runs 24/7 and every run, it set
variable_x = tag value
at the very beginning.
At the very end of my script before it goes back to beginning, it will set
prev_variable_x = variable_x
.
This is just 1 example, but in general my script looks at hundreds of tags.
Does these scripts have a way to do something like tag.getPreviousValue() and tag.getCurrentValue() or something like that?
