8.7.8

Service Interval (4.16.)

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 Device Lifetime, Service Interval, and Calibration Interval.
● The device operates in years. To view Remaining Sensor Lifetime parameters in hours or
days (via SIMATIC PDM only) see Total Expected Sensor Life.
The device tracks service intervals based on operating hours and monitors the predicted
lifetime to the next service. You can modify the Total Service Interval, set 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 Service Interval 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 Service Performed to restart the timer and clear any fault messages.
