Section 3 NAME AND FUNCTION OF EACH PART
(2) Basic procedure
(a) Measuring periodic electric energy
(i) Check that Periodic electric energy measurement flag (Yn1/Yn2) is OFF.
(ii) Check periodic electric energy (Un\G114, 115/Un\G116, 117).
(iii) 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.
(iv) 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.
(v) Check that Periodic electric energy data completion flag (Xn1/Xn2) becomes ON, and obtain the
value of periodic electric energy.

(b) Resetting periodic electric power
(i) Check that Periodic electric energy measurement flag (Yn1/Yn2) is OFF and Periodic electric energy
reset request (Yn3/Yn4) is OFF.
(ii) 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.
(iii) Check the Periodic electric energy reset completion flag (Xn3/Xn4) has become ON, then set Periodic
electric energy reset request (Yn3/Yn4) to OFF.
Periodic electric energy reset completion flag (Xn3/Xn4) will be turned OFF.
