Parameters
4.6. LCD Contrast
The factory setting is for optimum visibility at room temperature and in average light
conditions. Extremes of temperature will lessen the contrast.
Adjust the value to improve visibility in different temperatures and light conditions.
Change the value in small steps to ensure you can continue to read the display.
4.7. 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 reminders, and acknowledge them.
The maintenance warnings and reminders are communicated to the end user
through status information. 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.
Time Units
Values
Range: 0 to 20.
Default: 8
Contrast setting will depend on ambient
temperature.
Notes:
• 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 Calibration Schedule (4.8.).
• 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 (4.7.6.).
