4.9. Service Schedule
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 via the Status byte. 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 Schedule 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.
Notes:
• Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and
set up Service/Calibration schedules, based on operating hours instead of a
calendar-based schedule. See also Remaining Device Lifetime (4.7.), Remaining
Sensor Lifetime (4.8.), and Calibration Schedule (4.10.).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule
parameters to their factory defaults.
• The device operates in years. To view Service Interval parameters in hours or
days (via SIMATIC PDM only) see Service Interval (4.9.1.).
