5 I/O signal to CPU module
5.2.2 Output signals
(1) Periodic electric energy 1 measurement flag (Yn1)
(a) When switching this signal (Yn1) from the ON status to the OFF status, the periodic
electric energy 1 is measured, and will be stored into the buffer memory.
(b) When this signal (Yn1) is turned OFF, Periodic electric energy 1 data completion flag
(Xn1) is turns ON at the time that the periodic electric energy 1 is checked for that period,
and then the periodic electric energy 1 is retained.
(c) In order to read the checked data of the periodic electric energy 1, using the sequence
program, use Periodic electric energy 1 data completion flag (Xn1) as the interlock
condition.
*For specific usage procedures, refer to section 4.2.2.
(2) Periodic electric energy 2 measurement flag (Yn2)
The usage procedure is the same as that of Periodic electric energy 1 measurement flag
(Yn1). Refer to (1).
(3) Periodic electric energy 1 reset request (Yn3)
(a) When this request (Yn3) is turned ON from the OFF status, Periodic electric energy 1
reset completion flag (Xn3) turns ON, and the periodic electric energy 1 that has been
stored in the buffer memory is reset.
(b) Regardless of the status of Periodic electric energy 1 measurement flag (Yn1), either OFF
or ON, the periodic electric energy can be reset using this request (Yn3). When Periodic
electric energy 1 measurement flag (Yn1) is ON, and the measurement is taking place, the
measurement will resume immediately after the reset.
(c) When this request (Yn3) is set to OFF, Periodic electric energy 1 reset completion flag
(Xn3) turns OFF.
*For specific usage procedures, refer to section 4.2.2.
(4) Periodic electric energy 2 reset request (Yn4)
The usage procedure is the same as that of Periodic electric energy 1 reset request (Yn3).
Refer to (3).
(5) Operating condition setting request (Yn9)
(a) When switching this request (Yn9) from the OFF status to the ON status, the following
operating conditions will be set.
- Phase wire system (Un\G0)
- Primary 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)
- Alarm 1 reset method (Un\G14)
- Alarm 1 delay time (Un\G15)
- Alarm 2 item (Un\G21)
- Alarm 2 value (Un\G22)
- Alarm 2 reset method (Un\G24)
- Alarm 2 delay time (Un\G25)
- output period of data acquisition clock (Un¥G60,61)
