6.7 Boot Cycle Counter
6.7.1 Description
After each start, the current Boot Cycle Counter is read
from the non-volatile memory, incremented by 1 and
rewritten. In addition, a second Boot Cycle Counter is
implemented that can be reset.
The output of the current boot cycle can serve as a control
for the service interval as well as for preventative
maintenance. Schedules for regular maintenance can be
tied to the values of the Boot Cycle Counter.

Object ID Name Description Direction
0x001E (30) Boot Cycle Counter Output of the current Boot Cycle Counter Input
