8.7.18 Calibration Interval (CALIB. INTERVAL) (4.17.)
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 calibration intervals based on operating hours and monitors the predicted
lifetime to the next calibration. You can modify the Total Calibration Interval, set schedules for
Maintenance Alerts, and acknowledge them.
To access these parameters via SIMATIC PDM:
Open the menu Device – Maintenance and select the Calibration 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 Calibration Performed to restart the timer and clear any fault messages.
8.7.19 Time Last Calibrated (TIME LAST CAL.) (4.17.1.)
Time elapsed since last calibration Can be reset to zero via the handheld programmer (after
performing a service).
To reset to zero:
In SIMATIC PDM, open the menu Device – Maintenance, click on the Calibration Interval
tab, and click on Calibration Performed to restart the timer and clear any fault messages.
Via the handheld programmer, manually reset Time Last Calibrated to zero.
8.7.20 Remaining Lifetime (REMAIN LIFETIME) (4.17.2.)
Read only. Total Calibration Interval less Time Last Calibrated.
