3.3.5. Service Schedule
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.).
The device tracks service intervals based on operating hours and monitors the
predicted lifetime to the next service. You can modify the Total Service Interval,
set schedules for maintenance reminders, and acknowledge them.
