We have a chemical mixing system controlled by Contrologix and display functions by FactoryTalk SE. On one of the process screens there is an actual temperature display and below it is an high temperature alarm setting for a particular grinding mill. The operator has the capability to change the high temperature setting if needed. However, we would like to set a maximum limit that the display will accept. Is this best done in the PLC program or in the FTSE configuration? I am looking for ways this could be done. Thank you for all your help.
