NI 9211 (FPGA Interface)
CompactRIO 4-Channel, ±80 mV, 24-Bit Thermocouple 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 |
|---|---|
| TCx | Thermocouple input channel x, where x is the number of the channel. The NI 9211 has TC channels 0 to 3. |
| CJC | Cold-junction compensation channel. For the best accuracy, read the CJC channel in the same FPGA I/O Node as the thermocouple input channels. You must convert the CJC data to temperature. |
| Autozero | Autozero channel. For the best accuracy, read the Autozero channel in the same FPGA I/O Node as the thermocouple input channels. |
Arbitration
This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.
Methods
This device does not support any methods.
Module Properties
