I have a DeltaV DCS where the operators share a common login and where they do not have permission to change alarm area filtering on their workstations. However on two of the workstations I need to allow the operators to toggle the filtering of two specific alarm areas on demand without affecting the configuration of the other alarm areas on those stations.
For example, I was thinking of creating a button to execute a toggle like this:
ToggleDigitalPoint "THISUSER/AREAFILT[1].F_CV"
The problem I have is that of parameter security. I need to allow a specific alarm area filter to be toggled when the button is clicked and parameter security is preventing the action. Is this possible, or is there a different approach I should explore?
