Reset operating hours counters
Introduction
At the beginning of a new work order, it may be useful to reset the operating hours counters
of the Energy Meter. Resetting here means that the operating hours counters are reset to
their start value.
The following section describes how you
● Reset operating hours counters via the outputs of the user data.
● Reset operating hours counters via data record 143.
8.2.1
Reset operating hours counters via user data
Introduction
Due to the differing lengths of the output data resetting of the operating hours counters
depends on the configured module version.
If you use module versions with 12 bytes output data, you can
● Reset operating hours counters for all phases.
● Reset operating hours counters for each individual phase.
If you use the module version with 2 bytes output data, you always reset all the operating
hours counters simultaneously. Differentiated resetting of the counters by phases is only
possible via data set DS 143 for this module version, see section Structure for energy
counters (DS 143) (Page 159).
Procedure at module version with 12 bytes of output data
Set the reset bit (Bit 5) in Control byte 1 from 0 to 1 through an edge change.
