52 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 Input Function The PC card converts analog signals to digital data according to the resolution and stores it in memory. You can set a variety of conditions for analog input, including the input channel, sampling period, and sampling start/stop conditions. Analog input processes are classified as follows: 1.Setting the Conversion Condititions 2.Starting/Stopping Operation 3.Monitoring the Status and Acquiring Data Resolution Input Mode Channel Range Memory Repeat Start Stop Status Sampling Repeat Data aquisition Clock Start Condition Stop Condition Delay Event 4.Reset Status Memory 5.Extended function Synchronized Sampling AD12-8(PM) 45

53 4. Functions 1. Setting the Conversion Conditions First, set the conditions for executing analog input. Resolution Resolution signifies the number of bits used by an analog input device to represent analog signals. The higher the resolution, the more finely the voltage range is segmented, allowing the device to convert analog values to digital equivalents more precisely. A device with a resolution of 12-bit divides the range width into 4096 segments. When the device covers the range of 0-10 volts, the minimum unit of converted voltages is mV. If the device has a resolution of 16-bit, it is mV instead. AD12-8(PM) : The resolution is 12-bit. Input Mode This device has single ended inputs only. This cannot be changed. Channel A channel indicates a single analog input point. See "Connector Pin Assignment" in Chapter 3 for details of the channel numbers. You can perform analog input for the desired number of inputs by specifying the channels in the software. Range The range means the permitted voltage range for analog input. The input range for this device is fixed at V. 46 AD12-8(PM)

54 4. Functions Memory You can use the conversion data memory on the device or in the driver to perform sophisticated and high-speed analog input processing. Depending on your requirements, you can set the memory operation to FIFO or ring format by software. - FIFO format In the FIFO (First In First Out) format, input data items are read from memory in the same order in which they were written to the memory. Input data items are fed out of the memory sequentially, where the oldest one is always read from the memory. The status monitor and application notification functions are provided, which check and report the state in which the memory has stored a fixed amount of data or in which the memory has become full. The FIFO memory is used to obtain all input data from analog input in a short or infinite period of time. - Ring format In the ring format, the memory contains storage areas arranged in a ring. Input data items are written to the memory sequentially. When it stores data exceeding the limit, it overwrites the area storing the previous item of input data. The status monitor and application notification functions are provided, which check and report the state in which data has been written to certain areas of memory. The ring memory is used to obtain data where conversion has stopped due to some event, usually without obtaining data in the normal state. AD12-8(PM) 47

55 4. Functions Repeat Repeat indicates the number of repetitions of sampling to be executed, from when the sampling start condition is satisfied until the end of sampling, including delayed sampling. The number of repetitions is set by means of software, for which conversion is repeated. You can set an infinite number of repetitions, in which case the conversion is terminated by the software abort command. Input data items are stored to the memory sequentially. The repetition state can be subject to status monitoring and application notification. The repeat function on the device cannot be used when the sampling start condition is set to software. Clock The sampling clock controls the sampling frequency. You can select either the internal sampling clock, or external sampling clock The sampling clock is selected by means of software. - Internal sampling clock This uses the signal from the clock generator on the device. - External sampling clock The edge of the digital signal input from an external device is used for the sampling clock. 48 AD12-8(PM)

56 4. Functions Start Condition The condition for controlling the start of sampling can be selected from among software and input data comparison. The conditions for controlling the start and stop of sampling are completely independent of each other; they can be set separately. - Software The PC card starts sampling and storing input data to memory immediately after the operation start command is issued. - Input data comparison When the operation start command is issued, the PC card compares the analog signal input through a specified channel to the value of the preset comparison level. If the analog signal satisfies the condition, the PC card starts storing input data. Level comparison conditions are set as two conditions: level and direction. The above sketch shows that the level comparison condition is satisfied in the rising direction. The start condition is satisfied when the analog signal at the specified channel passes the comparison level in the rising direction. Input data items are stored to memory, starting with those at solid dots. The above sketch shows that the level comparison condition is satisfied in the falling direction. The start condition is satisfied when the analog signal at the specified channel passes the comparison level in the falling direction. Input data items are stored to memory, starting with those at solid dots. If you set the level comparison directions to both directions, the start condition is satisfied when the analog signal passes the level both in the rising and falling directions. AD12-8(PM) 49

57 4. Functions Stop Condition The condition for controlling the stop of sampling can be selected from among the last sampling count, input data comparison, and software abort. The PC card stops sampling whenever an error occurs irrespective of the stop condition setting. - Last sampling count The PC card stops sampling after storing input data to memory for the specified number of times of sampling. - Input data comparison Once the PC card has started sampling, it compares the analog signal input through a specified channel to the value of the preset comparison level. If the analog signal satisfies the condition, the PC card stops sampling. Level comparison conditions are set as two conditions: level and direction. The above sketch shows that the level comparison condition is satisfied in the rising direction. The stop condition is satisfied when the analog signal at the specified channel passes the comparison level in the rising direction. Input data items are stored to memory, ending until those at solid dots. The above sketch shows that the level comparison condition is satisfied in the falling direction. The stop condition is satisfied when the analog signal at the specified channel passes the comparison level in the falling direction. Input data items are stored to memory, ending until those at solid dots If you set the level comparison directions to both directions, the start condition is satisfied when the analog signal passes the level both in the rising and falling directions. - Software Sampling continues indefinitely in this mode. command or an error. Sampling only stops in response to a software 50 AD12-8(PM)

58 4. Functions Delay Delayed sampling is performed after the sampling stop condition is satisfied. When a sampling stop condition other than the software abort command is satisfied, the PC card performs sampling for the specified number of times of delayed sampling to store input data to memory. If you set the number of times of delayed sampling to 0, the PC card stops sampling the moment the sampling stop condition is satisfied. Event Event works as a function for reporting the occurrence of a certain PC card state to the application. The following events can be used in combination depending on the specifications and purpose of the application. - AD conversion start condition satisfied event This event occurs when the AD conversion start condition is satisfied. The event is nullified when the conversion start condition is software. - Repeat end event This even occurs whenever a repetition is completed. - End of device operation event This event occurs when the entire operation including repetitions is completed. - Stored specified sampling times event This event occurs when sampling has been performed for the number of times set by software. This event can only be used in device buffer mode. - "Specified number of transfers" event This event occurs each time a specified number of samples (set by software) has been completed. This event can only be used in user buffer mode. - Overflow event This event occurs at an attempt to store input data with the memory full. - Sampling clock error event This event occurs when conversion stops as an error occurs due to a sampling clock period that is too short. - AD conversion error event This event occurs when conversion stops due to an AD conversion error. 2. Starting/Stopping Operation Sampling is started by the software command. Once started, sampling can be stopped by the software command at any timing. AD12-8(PM) 51

59 4. Functions 3. Monitoring the Status and Acquiring Data Software commands are used to monitor the operation status of the device and to acquire input data from memory. Status monitoring and data acquisition can be performed even during sampling. Status The current state of the device can be checked by obtaining the device status. The following types of device status are available: - Device operating The device operating status remains ON, after the execution of the sampling start command until the PC card completes conversion, aborts operation due to an error, or stops sampling in response to the command. - Waiting for start trigger This status remains ON, after the PC card starts sampling until the start trigger is input, if the conversion start condition is level comparison. The status is set to OFF when the input trigger is input to start conversion. The status is set to ON whenever the PC card enters the conversion start wait status even when repeated operation has been set. - Specified sampling data stored This status is set to ON when input data stored in memory has reached the amount corresponding to the preset number of times of sampling. If the memory format is FIFO, the status is set to OFF when the amount of input data in the memory falls below the value corresponding to the preset number of times of sampling as data is acquired. Once the status is set to ON when the memory format is ring, it remains ON until it is reset. - Overflow An overflow error occurs when an attempt is made to store input data to memory while it has been full of input data. When the memory format is FIFO, the PC Card stops conversion. When the memory format is ring, the PC Card continues conversion while overwriting existing data with new one. - Sampling clock error This error occurs when the sampling clock period is too short. - AD conversion error If the device operating status remains ON (without terminating conversion) for an extended period of time, the driver regards that state as an operation error and sets this status to ON. This error stops sampling. Sampling The number of sampled items of input data stored in memory can be obtained by the software command. Repeat The current repeat count can be obtained by the software command. 52 AD12-8(PM)

60 4. Functions Data acquisition You can use a software command to retrieve the conversion data from memory. The figure below shows the relationship between the conversion data stored in memory and the sampling count and conversion channels. Input data is acquired differently depending on the memory format used. - Data acquisition in FIFO format When FIFO memory is used, the oldest data is always read first. The following sketch shows an image of data acquisition in FIFO format. When data is acquired from the memory, the free memory space increases by that data size. When data is acquired next, the oldest one of the existing data items is taken from the memory in the same way. The FIFO memory deletes data once that data is acquired. AD12-8(PM) 53

61 4. Functions - Data acquisition in ring format When ring memory is used, data is read always with respect to the current input data write position. The following sketch shows an image of data acquisition in ring format. The sampling count obtained is always the number of times of sampling for up to the latest data (shaded portion below). The larger the number of samples taken, the older the data item acquired first. As the ring memory retains data even after that data is acquired, you can fetch the same data any number of times. Conversion data The following equation represents the relationship between input data and voltage. Voltage = Input data x (Max. range value Min. range value) / Resolution + Min. range value The value of resolution for the 12-bit device is 4096; that for the 16-bit device is The table below shows the relationship between input data and voltage in the ±10-volt range. Voltage Conversion data (12-bit) Voltage Conversion data (16-bit) V V : : : : 0.005V V V V V V : : : : V V 0 Ex.: When input data 3072 is input at a resolution of 12-bit in the ± 10-volt range Voltage = 3072 (10 - (-10)) (-10) = AD12-8(PM)

62 4. Functions 4.Reset Various states can be reset by executing the following reset commands: All reset Performs a full reset of the device. power. This restores the device to its state immediately after turning on the Status This command resets the sampling clock error status and AD conversion error status. Memory This command resets the following memory related states. - Resets the sampling count to 0. - Sets the status indicating whether the specified number of samples have been saved to OFF. - Resets the buffer overflow status. - Resets the repeat count to Extended function Synchronized Sampling Synchronized sampling performs AD conversion for multiple channels at the same time at the sampling clock timing. You can use the ATSS-16 synchronized sampling unit (sold separately) to perform sampling for 8 channels simultaneously. See "Connecting an ATSS-16 Synchronized Sampling Unit" in Chapter 3. AD12-8(PM) 55

63 4. Functions Analog Output Function The PC card converts digital data to analog signals according to the resolution. 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. A device with a resolution of 12-bit divides the range width into 4096 segments. When the device covers the range of 0-10 volts, the minimum unit of converted voltages is mV. If the device has a resolution of 16-bit, it is mV instead. AD12-8(PM) : The resolution is 12-bit. * The output range of AD12-8(PM) is designed so that the minimum unit of the converted voltage may be set to 1mV. Channel "Channel" represents each point of analog output. For individual channel numbers, see "Using the On-board Connectors" to "Connector Pin Assignment" in Chapter 3 "External Connection". You can specify an arbitrary number of points of analog output by setting the channels by means of software. Range "Range" means the range of voltages at which analog output can be performed. The output range of this device cannot be changed from V. 56 AD12-8(PM)

64 4. Functions Output data Set the data to output as an analog signal. You can use a software command to output from a single channel or from multiple channels (a specified number of channels starting from channel 0). The formula below gives the relationship between the output data and voltage on the AD12-8(PM). Output data = (Voltage x 4096) The table below lists the output voltage for different output data values. Voltage Output data(12-bit) V 4095 : : V V V 2047 : : V 0 Ex.: When 3V is output at a resolution of 12-bit. Output data = = 3000 AD12-8(PM) 57

65 4. Functions Digital Input Function Input bit Individual digital input points are called input bits. When the number of input points of a device is 4, the bits are determined as bit 0 - bit 3. Bit 3 Bit 2 Bit 1 Bit 0 Input in Bits The state 1 (ON) or 0 (OFF) of each input bit can be obtained by specifying the bit. Input in Bytes Individual input bits can be input in byte units. When the number of input points of the device is 4, the individual input bits are arranged as shown below and the byte data to be input is a value between 0 and 15 depending on the states of the bits.

When the number of output points of a device is 4, the bits are determined as bit 0 - bit 3. Bit 3 Bit 2 Bit 1 Bit 0 Output in Bits The state of each output bit can be changed to ON or OFF by specifying the bit and setting it to 1 or 0. Output in Bytes Individual output bits can be output in byte units. When the number of output points of the device is 4, the individual output bits are arranged as shown below and byte data to be output is a value between 0 and 15. Ex.
