Operating Hours Counter

5.4.1 Description
The operating hours counter can record the operating
hours of a device accurately to the second. There are a
total of three operating hours counters. In addition to an
operating hours counter for the operating hours since the
start of the device, there is a total operating hours counter
and a customer-specific operating hours counter that can
be reset. The storage interval is configurable and the
operating hours are not stored once 1,000,000 storage
cycles have been reached.
5.4.2 Algorithm
While the counter is incremented every second, the
storage interval doubles after each save operation. Starting
with a save operation after 1 minute, then after 2 minutes,
then after 4 minutes, then after 8 minutes, up to a
maximum storage rate of 12 minutes.

Tab. 5-20: Operating hours counter – ISDU
The maximum counter value that can be saved is
1,000,000 and, with a switch-on and switch-off
every 12 minutes (with static counter), this means
a service life of over 20 years.
If switched on and off more frequently or in the
case of dynamic storage, the maximum storage
time is reduced depending on the application.

The output of the operating hours can serve as a time
control for the service interval as well as for preventative
maintenance. Schedules for regular service can be tied to
the operating hour values. Moreover, a high value of the
total operating hours is indicative of intensive use of a
device and possible deterioration of the performance. The
risk of failure can be countered preventatively through
replacement.
