HSC Module Features

The IO-SHSC02 module supports the following features:

• Pulses in a wide range can be counted.
  • The range is -2,147,483,648 ~ 2,147,483,647 (signed 2³²).
  • A counted value is saved in buffer memory as signed 32-bit binary value.
• The pulse input type can be selected.
  • 1-Phase Input 1-Multiplication (1-p input 1-m)
  • 1-Phase Input 2-Multiplication (1-p input 2-m)
  • Clockwise/Counter-Clockwise
  • 2-Phase Input 1-Multiplication (2-p input 1-m)
  • 2-Phase Input 2-Multiplication (2-p input 2-m)
  • 2-Phase Input 4-Multiplication (2-p input 4-m)
• The counting form can be selected.
  • Linear counting:
    • Input pulses are counted from -2,147,483,648 ~ 2,147,483,647.
      • If the value is out of range, overflow occurs.
  • Ring counting:
    • Input pulses are counted repeatedly between the minimum and maximum values.
• Coincidence output is available.
  • Output can be toggled ON or OFF by comparing the current value with a set coincidence value.
• Four counting functions can be selected.
  • Latch counting:
    • The currently counted value is saved in buffer memory 4 (04H), 5 (05H), 36 (24H), and 37 (25H).
      • This is according to the signal to begin counting, Yn.6 and Yn.E.
        • n is the module’s position in the chassis
  • Sampling counting:
    • The value counted for the time set by the signals to start counting, Yn.6 and Yn.E, is saved in buffer memory 6 (06H), 7 (07H), 38 (26H), and 39 (27H).
      • If a set time has passed, the value counted before signals Yn.6 and Yn.E are input will be kept.
  • Periodic pulse counting:
    • The values saved in buffer memory 8 (08H), 9 (09H), 40 (28H), and 41 (29H) counted before the time set up by the signals Yn.6 and Yn.E are currently counted values, saved in buffer memory 10 (0AH), 11 (0BH), 42 (2AH), and 43 (2BH) are saved in buffer memory.
  • Disable Counting:
    • If the signals, Yn.6 and Yn.E, or the signals to enable count, Yn.4 and Yn.C, are OFF (0), pulses will not be counted.
      • The counted values are accumulated in buffer memory 0 (0H) and 1 (01H) for saving the current count.
• The preset and counting function can be processed by outer control signals.
