CompactRIO 4-Channel, ±10 V, 16-Bit Simultaneous, Channel-to-Channel Isolated Analog Input Module
|Note You can simultaneously read from multiple channels on the NI 9222.|
You can use the following User-Controlled I/O Sampling functions to perform I/O with more specific control over the I/O hardware on the FPGA.
|Generate I/O Sample Pulse Method||Module function|
|Get I/O Read Status Method||I/O function|
|Read I/O Method||I/O function|
|Reset I/O Method||Module function|
|Note You must call the Reset I/O Method function first to prepare the NI 9222 to use the other User-Controlled I/O Sampling functions.|
Use the FPGA I/O Node or User-Controlled I/O Sampling functions to access the following terminals for this device.
|AIx||Analog input channel x, where x is the number of the channel. The NI 9222 has AI channels 0 to 3.|
This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.
This device does not support any methods.
Use the FPGA I/O Property Node to access the following I/O properties for this device.
|LSB Weight||Returns the LSB weight in nV/LSB for the channel. Use this value to convert and calibrate NI 9222 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box.|
|Offset||Returns the calibration offset in nV for the channel. Use this value to convert and calibrate NI 9222 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box.|
Use the FPGA I/O Property Node to access the following module properties for this device.
|Module ID||Returns the module ID, 0x7445.|
|Serial Number||Returns the unique serial number of the module.|
|Vendor ID||Returns the NI vendor ID, 0x1093.|
This device does not support the single-cycle Timed Loop.
