6. Maintenance Settings (MAINT SET)
Use these parameters to set up schedules for calibration and maintenance. The device
will track itself based on operating hours, instead of a calendar-based schedule, and will
monitor its predicted lifetime.
The maintenance warnings and alarms are communicated to the end user through either
the status or condensed status bytes. 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.
6.1. Remaining Device Lifetime (DVC REMLIF)
Performing a reset to Factory Defaults will reset all Maintenance

parameters to their factory defaults.
The Remaining Device/Sensor Lifetime parameters set up schedules for calibration
and maintenance.
