There has been a request for me to setup one of our machine HMI's to record a change in a setpoint. It needs to show what the last setpoint was before it was changed. Ex: Current - 310, Last - 305. The system in place is a PanelView Plus 6 which is running with a 1768-L43 Compact Logix. Ive been trying to come up with the best way to do this and tested a few things but i havent got it to work yet.
The reason for this is because operators like to finger the screens when they have issues instead of calling for maintenance support until they make it alot worse. There are already passwords in place to "prevent" this but somehow production always gets them.
Thanks for any help yall can offer.
