The details of the I/O signals for the QD62(E/D) are listed in the table below.
(1) Input signals
Signal name
Turns ON when the count preparation for QD62(E/D) is completed at the
time of programmable controller CPU power on or reset operation, and
count processing is performed.
When Module ready (X00) is OFF, count processing is not performed.
Turns ON when the present value (CH1: 2H to 3H, CH2: 22H to 23H) >
coincidence output point No. 1 setting (CH1: 4H to 5H, CH2: 24H to 25H).
Turns OFF when the present value
setting.
Turns ON when the present value = coincidence output point No.1 setting
and the present value is latched.
Turns OFF with the coincidence signal No.1 reset command (Y00/Y08).
The counter value coincidence (point No.1) turns ON immediately after
power-ON or reset of the programmable controller CPU, since the present
value and coincidence output point No.1 are all '0'.
Turns ON when the present value < coincidence output point No.1 setting.
Turns OFF when the present value
setting.
Turns ON with a preset command signal from the external input terminal,
and the request is latched.
Turns OFF with the external preset detection reset signal (Y05/Y0D).
Turns ON when the present value > coincidence output point No.2 setting
(CH1: 6H to 7H, CH2: 26H to 27H).
Turns OFF when the present value
setting.
Turns ON when the present value = coincidence output point No.2 setting
and the present value is latched.
Turns OFF with the coincidence signal No.2 reset command (Y07/Y0F).
The counter value coincidence (point No.2) turns ON immediately after
power-ON or reset of the programmable controller CPU, since the present
value and coincidence output point No.2 are all '0'.
Turns ON when the present value < coincidence output point No.2 setting.
Turns OFF when the present value
setting.
Fuse broken detection flag (X0F) turns ON when a fuse in the coincidence
signal output section is blown.
