Is there a way to access components of the PLC Alarm tag? I would like to create a widget for my ALMA blocks that show setpoints and have an analog bar showing the input value and alarm setpoints

All the components that make up a PLC Alarm tag can be accessed via tags.

On the IO tab the 'PLC Alarm Block Name' links to the block, 'MyALMA'. For the alarm setpoint either Import via the Rockwell Driver import function or create an IO tag with the address 'MyALMA.LLLimit'.
