8.6.6 Remaining Device Lifetime (REMAIN. DEV. LIFE.) (3.15.)
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 Sensor Lifetime (Page 98), Service Interval (Page 105),
and Calibration Interval (Page 108).
Performing a Device Reset to Factory Defaults using the handheld programmer 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 Total Expected Device Life (Page 102).
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 alerts, and
acknowledge them.
The maintenance warnings and alarms are communicated to the end user through status
information. 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.
To access these parameters via SIMATIC PDM:
Open the menu Device – Maintenance and select the Remaining Device Lifetime tab.
After modifying values/units as required, click on Write to accept the change, and Read to
view the effect of the change.
Click on Snooze to add a year to the Total Expected Device Life.
8.6.7 Total Device Operating Time (TOTAL OP. TIME) (3.15.1.)
