    Sampling start/stop When the counter start trigger is used for starting sampling, the board starts counting and sampling synchronously. When the counter stop trigger is used for stopping sampling, the board stops counting and sampling synchronously in the same way. CNT32-4MT(LPCI)

  • Page 55: Preset

    When the control input pin is used for presetting, it cannot be used for the counter start/stop, zero-clear, or general-purpose input. Count match The counter is preset when the count value matches the value in comparison register 0 or 1. CNT32-4MT(LPCI)

  • Page 56: Zero-Clear

    The preset register is a 32-bit register to load the value in the preset register to the counter when presetting occurs. Comparison register 0, Comparison register 1 These are 32-bit registers.

    20MHz using the internal clock (for 1ch). As bus master transfer is used, an error occurs and transfer halts if the CNT32-4MT(LPCI) cannot obtain bus access in time for a transfer. Note that whether or not continuous transfer at 20MHz is possible depends on factors such as what other applications are running on the PC.

  • Page 61: Status, Count

    The 32-bit or 64-bit transfer count can be obtained by using the relevant API-CNT(98/PC) function in API-PAC(W32). The transfer count is obtained as the number of data items (per channel) which have been transferred to the memory area for the user application. CNT32-4MT(LPCI)

  • Page 62: Control Of A Sampling

    4. Functions Control of a sampling The CNT32-4MT(LPCI) can use a sampling clock to collect sampling data at fixed time intervals. The sampling clocks, sampling start triggers, and sampling stop triggers are listed below. Table 4.5. Sampling clock / start / stop...

  • Page 63: Hardware Event

    The pulse width can be set by software to 10 μ sec, 1msec, 10msec, or 100msec. When using the control output signal as a general-purpose output, the output becomes a level output and the above hardware events cannot be assigned. The logic polarity of the output signal can be set by software. CNT32-4MT(LPCI)

  • Page 64: Control Input Signal

    When the control input signal is set to counter start/stop, the control input pin serves as the external trigger input pin for counter start/stop. The rising or falling edge of the signal can be selected for each of the counter start and counter stop. CNT32-4MT(LPCI)

  • Page 65: Control Output Signal

    The logic polarity can be switched between positive and negative. Digital filter error A one-shot pulse is output to indicate a digital filter error if a pulse faster than the digital filter time setting is input.
