Procedure at module version with 12 bytes of output data
Resetting energy counters for all 3 phases
1. Select the categories of energy counter that you want to reset in byte 2.
– Set bit 5 for active energy counters.
– Set bit 6 for reactive energy counters.
– Set bit 7 for apparent energy counters.
Figure 7-3
2. Set the reset bit (bit 7) in byte 1.
If there is an edge change of the reset bit for energy counters from 0 to 1, the module
resets all energy counters that you previously selected in byte 2.
Figure 7-4
Procedure at module version with 2 bytes of output data
If you use the module version with 2 bytes of output data, you always reset all the energy
counters simultaneously. Set the reset bit (Bit 7) in Control byte 1 from 0 to 1 through an
edge change.
