7.4.5 Calibration schedule (4.5.)
Note
•
Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and set up
Maintenance/Service schedules, based on operating hours instead of a calendar-based
schedule, see also Remaining device lifetime (4.2.) (Page 121), Remaining sensor
lifetime (4.3.) (Page 124), and Service schedule (4.4.) (Page 126).
•
Performing a reset to Factory Defaults will reset all the Maintenance Schedule
parameters to their factory defaults.
•
The device operates in years. To view Calibration Interval parameters in hours or days
(via SIMATIC PDM only) see Calibration interval (4.5.1.) (Page 129).
Factory setting: years
