3.3.2
Functions of I/O signals
The following table shows the I/O signals of the QD63P6.
I/O numbers (X/Y) and buffer memory addresses in Description describe only for channel
1.
For I/O numbers (X/Y) and buffer memory addresses from channels 2 to 6, refer to Section
3.3.1 and Section 3.4.1.

Description
X00
Module READY
•Turns ON at reset or power-ON of the programmable controller CPU when counting
of the QD63P6 is ready, and the count processing is performed.
•Turns OFF when watchdog timer error or an error which affects the system (error
code: 810 to 850) occurs.
•The count processing is not performed when the module READY (X00) is OFF.
•This signal is used for an interlock of sequence programs.
X01
CH1
Counter value large
•Turns ON when the present value A (Un\G10 and 11)/present value B (Un\G200 and
201) Coincidence detection point setting (Un\G6 and 7).
•Turns OFF when the present value A (Un\G10 and 11)/present value B (Un\G200 and
201) Coincidence detection point setting (Un\G6 and 7).
•For details of the general operation, refer to Section 5.3.
