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)
Manual, 07/2018, A5E42674880-AA

Procedure for module version with 20 bytes of output data
Apply start values for energy counters and overflow counters for all three phases
1. In Byte 2 of the output data, select the categories for which you want to apply start
values.
– Set bit 5 for active energy counters.
– Set bit 6 for reactive energy counters.
– Set bit 7 for apparent energy counters.
Figure 7-3 Selection of categories for reset
2. Set the reset bit (Bit 7) in byte 1 of the output data.
Figure 7-4 Reset bit for energy and overflow counter
If there is an edge change of the reset bit from 0 -> 1, the module resets the energy and
overflow counters that you previously selected in byte 2 to their start values.
