3.3.5. Service Schedule
The device tracks service intervals based on operating hours and monitors the

set schedules for maintenance reminders, and acknowledge them.
Values
Range: 0.000 to 20.000 years
Default: 0.019 years (1 week)
Notes:
• 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 Life
(3.3.3.), Remaining Sensor Life (3.3.4.), and Calibration Schedule (3.3.6.).
• Performing a reset to Factory Defaults will reset all the Maintenance
Schedule parameters to their factory defaults.
• The device operates in years. To view Service Interval parameters in hours
or days (only via SIMATIC PDM, PACTware FDT, and AMS) see Service
Interval (3.3.5.1.).
