5 I/O signal to CPU module
(c) When this request (Yn9) is turned OFF, Operating condition setting completion flag (Xn9)
turns OFF.
(6) Alarm 1 reset request (YnA)
(a) When Alarm 1 flag (XnA) is reset, this request (YnA) turns ON.
(b) When this request (XnA) is switched from the OFF status to the ON status, Alarm 1 flag
(XnA) will forcibly be turned OFF regardless of the present alarm occurrence status.
(7) Alarm 2 reset request (YnB)
The usage procedure is the same as that of Alarm 1 reset request (YnA). Refer to (6).
(8) Integrated valve set request (YnC)
(a) If you want to set the energy (consumption and regeneration) and the reactive energy to
an arbitrary value, write Electric energy preset item (Un\G51) and Electric energy preset
value (Un\G52, 53) into it, and after that, turn this request (YnC) into ON.
(b) When switching this request (YnC) from the OFF status to the ON status, setting of the
integrated value will be performed. When the integrated value setting is completed,
Integrated valve set completion flag (XnC) turns ON.
(c) When this request (YnC) is set to OFF, Integrated valve set completion flag (XnC) turns
OFF.
(9) Max./min. values clear request (YnD)
(a) When the max./min. value data (max./min. value and their date/time of occurrence) is
reset, this request (YnD) turns ON.
(b) When switching this request (YnD) from the OFF status to the ON status, the max./min.
value data will be cleared. When clearing the max./min. data is completed, Max./min.
values clear completion flag (XnD) turns ON.
(10) Error clear request (YnF)
(a) When switching this request (YnF) from the OFF status to the ON status while an
outside-set-value error is present, Error flag (XnF) turns OFF, and the latest error code in
the buffer memory (Un\G3000) will be cleared.
(b) At the same time as clearing the error above, the value that was set in the buffer memory
below will be replaced with the previously set value, and Electric energy preset item
(Un\G51) and Electric energy preset value (Un\G52, 53) will be changed to 0.
[Set value to be replaced with the previously set value]
- Phase wire system (Un\G0)
- Input voltage (Un\G1)
- Primary current (Un\G2)
- Current demand time (Un\G3)
- Electric power demand time (Un\G4)
- Primary voltage of VT (Un\G5)
- Secondary voltage of VT (Un¥G6)
- Primary current of CT (Un¥G7)
- Alarm 1 item (Un\G11)
- Alarm 1 value (Un\G12, 13)
- Alarm 1 reset method (Un\G14)
- Alarm 1 delay time (Un\G15)
- Alarm 2 item (Un\G21)
- Alarm 2 value (Un\G22, 23)
- Alarm 2 reset method (Un\G24)
- Alarm 2 delay time (Un\G25)
- Output period of data acquisition clock (Un\G60, 61)
(c) While a hardware error is present (error code: 0000H to 0FFFH), it will not be cleared
even if this signal (YnF) turns ON.
