Programming the Operating Hours Counter
The operating hours counter is enabled with bit 9 of the status word. This allows you to establish,
for example, the number of hours a motor has been in operation. The operating hours counter is
only active in RUN mode.
Transferring Settings to the Operating Hours Counter
You can preset the operating hours counter to a specific initial value (e.g. after change of CPU).
•
The clock data must be transferred in BCD.
Note
The "KC" data format loads a BCD constant into accumulator 1 and is therefore
especially suitable for entering settings.
