Goal: This Python script checks to see if the object that was changed is for a given category. Specifically, it checks whether a Pressure object was changed and if so, it prints its name to the log file. The script drops any events that are not associated with the Pressure object. To view the log file, from the Workbench Project page, select Extensions > View Log File.
