4.2. Remaining Device Lifetime

Notes:
• Default settings in the parameter tables are indicated with an asterisk (*) unless
explicitly stated.
• Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and
set up Service/Calibration schedules, based on operating hours instead of a
calendar-based schedule. See also Remaining Sensor Lifetime (4.3.), Service
Schedule (4.4.), and Calibration Schedule (4.5.).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule
parameters to their factory defaults.
• The device operates in years. To view Remaining Device Lifetime parameters in
hours or days (via SIMATIC PDM only) see Lifetime Expected (4.2.1.).
The device tracks itself based on operating hours and monitors its predicted lifetime.
You can modify the expected device lifetime, set up schedules for maintenance
reminders, and acknowledge them.
The maintenance warnings and alarms are communicated via the Status byte. This
information can be integrated into any Asset Management system. For optimal use,
we recommend that you use SIMATIC PCS7 Asset Management Software in
conjunction with SIMATIC PDM.
