I have some I/O fields on the HMI that the operator can modify (DINT). I need to copy the value into a recipe database in the PLC when a value is changed. I see no built in property and the only events are "activate" or "deactivate". I could not find in the manual an explanation of what these do and the help file does not have any info.
How do you tell the PLC when the operator has modified the value?
