7.4 Resetting energy counters and overflow counters
Introduction
At the beginning of a new work order, it may be useful to reset the energy and overflow
counter of the Energy Meters Resetting here means setting the energy counters to their start
values and resetting the overflow counters to 0.
The following section describes how you
● Reset energy counters via the outputs of the user data.
● Reset energy counters and overflow counters via data record 143.

7.4.1

Reset energy counters via user data

Introduction
Due to the differing lengths of the output data resetting of the energy counters depends on
the configured module version.
If you use module versions with 12 bytes output data, you can
● Reset energy counters for all phases separately by active, reactive and apparent energy.
● Reset energy counters for each individual phase separately by active, reactive and
apparent energy.
If you use the module version with 2 bytes output data, you always reset all the energy
counters simultaneously. Differentiated resetting of the counters by active, reactive and
apparent energy is only possible via data set DS 143 for this module version, see section
Resetting energy counters and overflow counters via data record DS 143 (Page 50).
Requirements
Resetting of the energy counters is enabled via user data in the default setting and may not
be blocked n Control byte 1 of the data record 143.
