Remaining Device Lifetime; Remaining Sensor Lifetime - Siemens sitrans lr 460 Instruction Manual

6. Maintenance settings
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.
