  • Page 40: Functions

    4. Functions 4. Functions This chapter describes the different functions that can be implemented using the hardware and driver together. Unless stated otherwise, the driver is assumed to be API-AIO(WDM). Analog Output Function This product converts digital data to analog signals according to the resolution. You can set a variety of conditions for analog output, including the output channel, sampling period, and sampling start/stop conditions.

  • Page 41: Setting The Conversion Conditions

    4. Functions 1. Setting the Conversion Conditions First, set the conditions for executing analog output. Resolution "Resolution" signifies the number of bits used by an analog output device to represent analog signals. The higher the resolution, the more finely the voltage range is segmented, allowing the device to convert digital values to analog equivalents more precisely.
  • Page 42 4. Functions Output data Output data = ((Voltage – Min. range value) x Resolution) / (Max. range value – Min. range value) The value of resolution for the 16bit device is 65536. The table below shows the relationship between output data and voltage in the ±10-V range. Voltage Output data(16bit) +9.99970V...
  • Page 43 4. Functions Data transfer method A device buffer mode is available, which uses the device's or driver's conversion data storage memory. Device buffer mode The application output data is first stored in the device buffer (memory on the device itself or in the driver).
  • Page 44 4. Functions Memory format This product uses device buffer transfer mode; it does not require software setup of the memory format. Device buffer mode FIFO format Use FIFO format if you wish to output a continuous arbitrary analog output like that shown below. When using FIFO format, writing of conversion data to memory is always performed from after the most recent data and DA conversion is performed on the oldest data in memory.
  • Page 45 4. Functions Ring format Use ring format if you wish to output a repeated pattern like that shown below. When using ring format, write the data for one complete cycle of the output waveform before starting operation. You cannot write to the memory during its operation of analog output. DA conversion data is output continuously in the sequence in which the ring format data is stored.
  • Page 46 4. Functions Repeat You can specify a repeat count to perform sampling for a specified number of times. Memory must be set to ring format if a number of repetitions is to be specified. (The number of repetitions cannot be specified for FIFO memory format.) The number of repetitions is set by software and sampling is repeated for the specified number of times.
  • Page 47 4. Functions Procedure for RING format When using ring format, a ring memory area large enough for the data to be set is reserved. Data cannot be modified during DA conversion. Clock The sampling clock controls the sampling frequency. You can select either the internal sampling clock, or external sampling clock.
  • Page 48 4. Functions Stop Condition The condition for controlling the stop of sampling can be selected from among the last sampling count, an external trigger, and software abort. This product stops sampling whenever an error occurs irrespective of the stop condition setting. Last sampling count This product stops sampling after storing input data to memory for the specified number of times of sampling.

  • Page 49: Starting/Stopping Operation

    4. Functions 2. Starting/Stopping Operation Analog output operation is started by a software command (the analog output start command). Similarly, you can stop analog output at any time using a software command (the analog output stop command). 3. Monitoring the Status and Acquiring Data You can use a software command to check the status of analog output operation and of the output data stored in memory.

  • Page 50: Reset

    4. Functions 4.Reset Various states can be reset by executing the following reset commands: Status This command resets the sampling clock error status and AD conversion error status. Memory This can only be used when the transfer mode is set to device buffer mode. This command resets the following memory related states.

  • Page 51: Counter Function

    4. Functions Counter Function 1. Setting the Operating Conditions This specifies the conditions for counter operation. Operating conditions The basic operation of the counter is to count an external input signal. The counter includes a function to detect a count match and perform a specified operation when the current count value reaches a preset count value.

  • Page 52: Starting/Stopping Operation

    4. Functions Event The event function notifies the application when something occurs on the device. The following events can be used as required. Compare count match event This event is triggered when a compare match occurs on the counter. Count overrun event This event is triggered when a counter overrun occurs.

  • Page 53: Reset

    4. Functions 4.Reset Various states can be reset by executing the following reset commands: Counter reset Resets the counter. This restores the counter to its state after power on. Status Resets the compare count match status and overrun status. DA16-16(LPCI)L, DA16-8(LPCI)L...
