Parameters
4.8. Calibration Schedule
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 reminders, and acknowledge them.
To access these parameters via SIMATIC PDM:
• Open the menu Device – Maintenance and select the Calibration 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 Calibration Performed to restart the timer and clear any fault
messages.
Time Units
4.8.1. Time since Last Calibration
Time elapsed since last calibration. Can be reset to zero after performing a
calibration. Can be reset locally by entering 0 in this parameter.
To reset to zero:
• In SIMATIC PDM, open the menu Device – Maintenance, click on the
Calibration Schedule tab, and click on Calibration Performed to restart the
timer and clear any fault messages.
• Via the handheld programmer, manually reset Time since Last Calibration
(4.8.1.) to zero.
4.8.2. Time until Next Calibration
Read only. Calibration Interval (4.8.6.) less Time since Last Calibration (4.8.1.).
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 Device Lifetime (3.6.), Remaining
Sensor Lifetime (3.7.), and Service Schedule (4.7.).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule
parameters to their factory defaults.
• The device operates in years. To view Calibration Interval parameters in hours or
days (via SIMATIC PDM only) see Calibration Interval (4.8.6.).
