Input signal

(1) Module READY (X0)
Module READY (X0) turns on to indicate the preparation for the digital conversion is completed at the power-on or
reset operation of the CPU module.
Module READY (X0) turns off in the following cases.
• When the offset/gain setting mode is set (The digital conversion processing is executed.)
• When a watchdog timer error occurs in the CT input module (The digital conversion processing is not
executed.)
(2) Default setting completed flag (X5)
Use Default setting completed flag (X5) as an interlock condition to turn on then off Default setting request (Y5).
When the buffer memory settings return to the default by turning on Default setting request (Y5), Default setting
completed flag (X5) turns on. When Default setting request (Y5) is turned off, Default setting completed flag (X5)
also turns off.
The buffer memory areas which return to the default value are with
