I have been asked to add a feature in one of my modules to automatically enable/disable a selectable setpoint based on certain criteria.
To illustrate my point, here is an example of what I am looking for:
This module is using a Sequential Function Chart that changes "state" based on a separate module's operator setpoint selection.
Available Setpoint states:1- RESET2- HEAT-UP3- COOL-DOWN4- HOLD
I want to be able to remove the option to HEAT-UP given certain process conditions. The ideal situation is to not even show it on the faceplate or graphic drop-down menu.
I know Provox allows this sort of thing, with FST code like:LDSV (B14)DAWT (B, ENABSP[2]:SYSRAMP)
but I'm not entirely sure about DeltaV. Any ideas?
