[Operation details]
(a) At the rising edge of the signal "Power consumption computation: Clearing consumption accumulation 1 to 4 (IPCC1
to 4: Y700 to 3)", each of Accumulated power consumption 1 to 4 is cleared.
(b) While the power and the "Power consumption computation: Enable consumption accumulation 1 to 4 (IPCE1 to 4:
Y724 to 7)"are both ON, each of Accumulated power consumption 1 to 4 is integrated.
[Operation by PLC]
When the PLC turns ON the signal "Power consumption computation: Clearing consumption accumulation 1 to 4 (IPCC1 to 4:
Y700 to 3)", the "Power consumption computation: Clearing consumption accumulation 1 to 4 complete (IPCCC1 to 4: X708
to B)" is input to the PLC. Then the PLC turns OFF the "Power consumption computation: Clearing consumption accumulation
1 to 4 (IPCC1 to 4: Y700 to 3)".
When the "Power consumption computation: Clearing consumption accumulation 1 to 4 (IPCC1 to 4: Y700 to 3)" is turned
OFF, the "Power consumption computation: Clearing consumption accumulation 1 to 4 complete (IPCCC1 to 4: X708 to B)"
signal is also turned OFF.
