(1) Input signals
Signal name
PLC CPU
Turns ON when the count preparation for QD62(E/D) is completed at the
time of PLC 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: 2
coincidence output point No. 1 setting (CH1: 4
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).
Turns ON when the present value < coincidence output point No. 1
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: 6
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).
Turns ON when the present value < coincidence output point No. 2
setting.
Fuse broken detection flag (X0F) turns ON when a fuse in the
coincidence signal output section is blown.
