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.
