This section describes the input signals of the QD65PD2.
The I/O numbers (X/Y), buffer memory addresses, and external input terminals described in this section are for CH1.
To check the I/O numbers (X/Y) for CH2, refer to the following:
Page 32, Section 3.3.1
To check the buffer memory addresses for CH2, refer to the following:

(1) Module ready (X00)
• This signal turns on by powering on the CPU module or resetting it while the QD65PD2 is ready for count,
and the count starts.
• This signal turns off when a watchdog timer error or an error affecting the system (Last 3 digits of an error
code: 800 to 859) occurs.
• The count does not start when this signal is OFF.
• Use this signal for an interlock to turn on and off a sequence program.
(2) Operating condition settings batch-changed (X01)
• Use this signal for an interlock to turn on and off Operating condition settings batch-change command (Y01)
when selecting functions (the comparison output function, for instance) or changing setting values.
• The count doesn't start when this signal is OFF.
• This signal turns off in the following cases:
• Module ready (X00) turns off.
• Operating condition settings batch-change command (Y01) is turned off and on.
• This signal turns on in the following case:
• Operating condition settings batch-change command (Y01) is turned on and off when all setting values for
Pr1 or Pr2 (data classification) are normal.
• Confirm that operating condition settings are changed and that this signal is ON before turning on CH1
