Energy counters
7.2 Preset and apply start values for energy and overflow counters
Analog input module AI Energy Meter 480VAC/CT HF (6ES7134-6PA00-0CU0)
62 Manual, 07/2018, A5E42674880-AA
Apply start values for energy counters and overflow counters for phase-specific counting
You can also reset the energy and overflow counters on a phase-specific basis using the
output data.
Follow the procedure as described in "Applying start values for energy counters and overflow
counters for all three phases", as applicable.
1. In bytes 7, 9 and 11 of the output data, select the categories for which you want to apply
the phase-specific start values.
– Set Bit 5 for active energy counters.
– Set Bit 6 for reactive energy counters.
– Set Bit 7 for apparent energy counters.

2. In bytes 6, 8 and 10 of the output data, set the reset bits (Bit 7) for the phase-specific start
values.
Figure 7-6 Reset bit for phase-specific energy and overflow counters
If there is an edge change of the phase-specific reset bit from 0 -> 1, the module resets
the energy and overflow counters that you previously selected in bytes 7, 9 and 11 to
their start values.
