Appendix 1 Details of I/O Signals
This section describes the details on the I/O signals from the high-speed counter module to the CPU module.
The I/O numbers (X/Y) in this section are shown on the assumption that the start I/O number of the high-speed counter
module is set to 0.
Appendix 1.1 Input signals
(1) Module READY (X0)
• This signal turns on when the high-speed counter module is ready for counting operation after the CPU
module is powered on or is reset.
• Pulses are not counted while this signal is off.
(2) CH Counter value large (point No.1) (X1, X8)
• This signal turns on when CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is larger than CH
Coincidence output point No.1 (Un\G4, Un\G5, Un\G36, Un\G37).
• This signal turns off when CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is equal to or smaller than
CH Coincidence output point No.1 (Un\G4, Un\G5, Un\G36, Un\G37).
(3) CH Counter value coincidence (point No.1) (X2, X9)
• This signal turns on when CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is equal to CH
Coincidence output point No.1 (Un\G4, Un\G5, Un\G36, Un\G37). And then, the on status will be latched.
• This signal is turned off by CH Coincidence signal No.1 reset command (Y0, Y8).
• This signal is on immediately after the CPU module is powered on or is reset because both CH Present
value (Un\G2, Un\G3, Un\G34, Un\G35) and CH Coincidence output point No.1 (Un\G4, Un\G5, Un\G36,
Un\G37) are set to "0".
(4) CH Counter value small (point No.1) (X3, XA)
• This signal turns on when CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is smaller than CH
Coincidence output point No.1 (Un\G4, Un\G5, Un\G36, Un\G37).
• This signal turns off when CH Present value (Un\G2, Un\G3, Un\G34, Un\G35) is equal to or larger than
CH Coincidence output point No.1 (Un\G4, Un\G5, Un\G36, Un\G37).
(5) CH External preset request detection (X4, XB)
• This signal is turned on by a preset command from an external input terminal. And then, the on status will be
latched.
• This signal is turned off by CH External preset detection reset command (Y5, YD).
