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.
