Operating hours counter
Operating hours counter provides four retentive operating
hours counters. They are always retentive and can only be
selectively deleted with a reset command.
Retentive data volume
200 bytes is the maximum memory range for retentive data
(operating hours counters are not included).
Markers
A user-definable and contiguous marker range can be
declared as retentive.
Counters
All C.., CH.. and CI.. function blocks can be operated with
retentive actual values.
Data function blocks
A user-definable consistent data function block range can be
operated with retentive actual values.
Timing relays
A user-definable and contiguous range for timing relays can
be run with retentive actual values.
Requirements
In order to make data retentive, the relevant markers and
function blocks must have been declared as retentive.
Attention!
The retentive data is saved every time the power supply is
switched off, and read every time the device is switched
on. The data integrity of the memory is guaranteed for
10
10
read/write cycles.
