3.3.3. Remaining Device Life
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 reminders are available through HART
communications. This information can be integrated into an 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. (For more details see
Maintenance
in LUT400
Communications manual.

Time Units
Allows you to set the desired units.
3.3.3.1. Lifetime Expected
Allows you to override the factory default.
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 Sensor Life
(3.3.4.), Service Schedule (3.3.5.), 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 Remaining Device Lifetime
parameters in hours or days (only via SIMATIC PDM, PACTware FDT, and
AMS) see Lifetime Expected (3.3.3.1.).
