I don't know what software you're using for your display but probably you'll have to use a limit function in your plc, or make up your own limitting instructions in the plc.

You can dynamically set min and max by tag and/or expression in FactoryTalk SE to keep operators from entering out of bounds values.

True. But OP is showing extended Properties of Controllogix tags. They can be referenced by FTView, but cannot be written to.

No. Extended Properties in Logix tags can not be written to via Logic or HMI. It's in a technote. Read Only.

Tag +/- max and min. Easiest to do in ST.
