Peak value detector
The peak value detector detects two types of event:
• Occurrence of an extreme value of a measured variable (output current, supply voltage, temperature).
• Output of a warning message or error message.
The value of the maximum extreme value and the time of occurrence in input variables are available at all
times.
The following diagrams illustrate the mode of operation of the peak value detector taking the example of the
maximum of a measured variable:
