Remaining Device Lifetime - Siemens SITRANS LR560 Operating Instructions Manual

3.5.3. Internal Temperature
Read only. Displays (in degrees C) the current temperature on the circuit board
recorded by the internal electronics.
For access via SIMATIC PDM open the menu View – Process Variables and
check the field Electronics Temperature.

3.6. 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 Maintenance/Service schedules, based on operating hours instead of a
calendar-based schedule. See also Remaining Sensor Lifetime (3.7.), Service
Schedule (4.7.), and Calibration Schedule (4.8.).
• 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 (3.6.6.).
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.
• 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.
