7.4.2 Remaining device lifetime (4.2.)
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 Remaining sensor lifetime (4.3.) (Page 124), Service schedule (4.4.)
(Page 126), and Calibration schedule (4.5.) (Page 129).
•
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 (4.3.1.) (Page 124).
Factory setting: years
Setting range
1)
: hours, days, years
Purpose: The device tracks itself based on operating hours and monitors its predict-
ed lifetime. You can modify the expected device lifetime, set up schedules
for maintenance reminders, and acknowledge them.
Description: The maintenance warnings and reminders are available through HART
communications. This information can be integrated into an Asset Man-
agement 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:
1.
Open the menu Device – Maintenance and select the Remaining De-
vice Lifetime tab.
2. After modifying values/units as required, click on Write to accept the
change, and Read to view the effect of the change.
3. Click on Snooze to add a year to the Total Expected Device Life.

Selectable only via SIMATIC PDM.
