Section 4 I/O SIGNALS TO CPU MODULE
4.2.2 Output signals
(1) Periodic electric energy 1 measurement flag (Yn1)
While 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.
When this signal (Yn1) is turned OFF, Periodic electric energy 1 data completion flag (Xn1) is turns ON at
the time when the periodic electric energy 1 is settled for that period, and then the periodic electric energy 1
is retained.
In order to read the settled data of the periodic electric energy 1 by using the sequence program, use Periodic
electric energy 1 data completion flag (Xn1) as the interlock condition.
* For specific usage procedures, refer to "3.4.2".
(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)
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 to "0".
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.
When this request (Yn3) is set to OFF, Periodic electric energy 1 reset completion flag (Xn3) turns OFF.
*For specific usage procedures, refer to "3.4.2".
(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).
