NI 9206 (FPGA Interface)

CompactRIO 32-Channel Single-Ended/16-Channel Differential, ±200 mV to ±10 V, 16-Bit Analog Input Module

FPGA I/O Node

You can use an FPGA I/O Node, configured for reading, with this device.

Terminals in Software

Use the FPGA I/O Node to access the following terminals for this device.

Terminal	Description
AIx	Analog input channel x, where x is the number of the channel. The NI 9206 has AI channels 0 to 31. The channel is sampled using the currently configured terminal mode and voltage range. You can configure these settings at edit time using the C Series Module Properties dialog box or at run time using the Set Terminal Mode or Set Voltage Range methods.
DI0	Digital input channel used to access the module digital line, which is labeled PFI0.
Trig	Returns the output of the module trigger circuitry. Use the Set Triggers method to configure the trigger circuit.
DO0	Digital output channel 0.

Refer to the Conversion Timing topic for information about the order and timing of conversions for these I/O channels.

Arbitration

This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.

Module Methods

Use the FPGA I/O Method Node to access the following methods for this device. This device does not support any I/O methods.

Method	Description
IO Sample	Acquires a single sample from the module. The channel number, terminal mode, and voltage range are all configurable at run time. Note  National Instruments suggests that you do not configure the VI to run an IO Sample method and another FPGA I/O Method Node in parallel when both are targeted to the same C Series module. Similarly, National Instruments suggests that you do not configure the VI to run multiple IO Sample methods in parallel when the IO Sample methods are targeted to the same C Series module. Refer to the 9206 Basic IO VI and the NI 9206 Advanced IO VI in the labview\examples\CompactRIO\Module Specific\NI 9206\NI 9206 Basic IO and labview\examples\CompactRIO\Module Specific\NI 9206\NI 9206 Advanced IO directories for examples related to this method.

Set Terminal Mode	Sets the terminal mode for a channel as RSE (referenced single-ended), NRSE (non-referenced single-ended ), or DIFF (differential). This method overwrites the value you configure in the C Series Module Properties dialog box.
Set Triggers	Sets the trigger output to one of the following values: None AI Below Low AI Above High AI Inside Region AI Below Low with Hysteresis AI Above High with Hysteresis DI Trigger Refer to the 9206 Basic Triggering VI and the 9206 Advanced Triggering VI in the labview\examples\CompactRIO\Module Specific\NI 9206\NI 9206 Basic Triggering and labview\examples\CompactRIO\Module Specific\NI 9206\NI 9206 Advanced Triggering directories for examples related to this method.

Set Voltage Range	Sets the input range for a channel as ±10 V, ±5 V, ±1 V, or ±200 mV. This method overwrites the value you configure in the C Series Module Properties dialog box.

Module Properties

Use the FPGA I/O Property Node to access the following properties for this device. This device does not support any I/O properties.

Property	Description
Linearization Coefficient x	(Optional) NI-MCal linearization coefficient x, where x is the number of the linearization coefficient. The NI 9206 has linearization coefficients 3 to 0. You can use these coefficients in calibration to compensate for some types of measurement nonlinearity inherent in this device. Refer to the NI 9206 Advanced IO VI in the labview\examples\CompactRIO\Module Specific\NI 9206\NI 9206 Advanced IO directory for an example of this concept.  Open example
