(2) Basic procedure
1) Measuring periodic electric energy
(a) Check that Periodic electric energy measurement flag (Yn1/Yn2) is OFF.
(b) Check periodic electric energy (Un\G114, 115/Un\G116, 117).
(c) When starting measurement, set Periodic electric energy measurement flag (Yn1/Yn2) to
ON.
This module starts measuring specified periodic electric energy, and Periodic electric
energy data completion flag (Xn1/Xn2) will be turned OFF.
(d) When stopping measurement, set Periodic electric energy measurement flag (Yn1/Yn2)
to OFF.
This module stops measuring the specified periodic electric energy, and Periodic electric
energy data completion flag (Xn1/Xn2) will be turned ON.
(e) Check that Periodic electric energy data completion flag (Xn1/Xn2) becomes ON, and
obtain the value of periodic electric energy.

2) Resetting periodic electric power
(a) Check that Periodic electric energy measurement flag (Yn1/Yn2) is OFF and that Periodic
electric energy reset request (Yn3/Yn4) is OFF.
(b) Set Periodic electric energy reset request (Yn3/Yn4) to ON. The specified periodic electric
energy is reset to 0 kWh, and Periodic electric energy reset completion flag (Xn3/Xn4) will
be turned to ON.
(c) Check that Periodic electric energy reset completion flag (Xn3/Xn4) has become ON, and
then set Periodic electric energy reset request (Yn3/Yn4) to OFF.
Periodic electric energy reset completion flag (Xn3/Xn4) will be turned OFF.
