CompactRIO 8-Channel, ±20 mA, 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 9203 has AI channels 0 to 7. |
Arbitration
This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.
I/O Methods
This device does not support any I/O methods.
Module Methods
Use the FPGA I/O Method Node to access the following module method for this device.
| Method | Description |
|---|---|
| Set Input Range | Sets the input range for a channel as either 0–20 mA or ±20 mA. This method overwrites the value you configure in the C Series Module Properties dialog box. |
I/O Properties
Use the FPGA I/O Property Node to access the following I/O properties for this device.
| Property | Description |
|---|---|
| LSB Weight (±20 mA range) | Returns the LSB weight in pA/LSB for the channel. Use this value to convert and calibrate NI 9203 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box, and you set the input range to ±20 mA. |
| LSB Weight (4–20 mA range) | Returns the LSB weight in pA/LSB for the channel. Use this value to convert and calibrate NI 9203 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box, and you set the input range to 0–20 mA. |
Module Properties
Use the FPGA I/O Property Node to access the following module properties for this device.
| Property | Description |
|---|---|
| Module ID | Returns the module ID, 0x7129. |
| Offset (±20 mA range) | Returns the calibration offset in pA for the channel. Use this value to convert and calibrate NI 9203 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box, and you set the input range to ±20 mA. |
| Offset (4–20 mA range) | Returns the calibration offset in pA for the channel. Use this value to convert and calibrate NI 9203 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box, and you set the input range to 0–20 mA. |
| Serial Number | Returns the unique serial number of the module. |
| Vendor ID | Returns the NI vendor ID, 0x1093. |
Single-Cycle Timed Loop
This device does not support the single-cycle Timed Loop.
