CompactRIO 8-Channel, ±78 mV, 24-Bit, Channel-to-Channel Isolated Thermocouple Input Module
Use the FPGA I/O Node to access the following terminals for this device.
|TCx||Thermocouple input channel x, where x is the number of the channel. The NI 9212 has TC channels 0 to 7.|
|CJCx||Cold-junction compensation channel x, where x is the number of the channel. The NI 9212 has CJC channels 0 to 1. For the best accuracy, read the appropriate CJC channel in the same FPGA I/O Node as the corresponding thermocouple input channels. You must convert the CJC data to temperature.
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 I/O methods.
Use the FPGA I/O Method Node to access the following module method for this device.
|Check Cached Status||Returns Booleans for each channel that indicate whether the channel was out of range or had an open thermocouple since the last execution of the Check Cached Status method. When the FPGA I/O Node reads the channels, the FPGA VI determines the state of the channels and caches any TRUE value until the Check Cached Status method executes.
This device does not support any I/O properties.
Use the FPGA I/O Property Node to access the following module properties for this device.
|Conversion Time||Sets the time it takes to acquire one point of data from one or more channels in a single FPGA I/O Node. You can select High Speed, Best 60 Hz Rejection, Best 50 Hz Rejection, or High Resolution. Refer to the NI 9212 with NI TB-9212 Datasheet for more information about the High Speed, Best 60 Hz Rejection, Best 50 Hz Rejection, and High Resolution conversion times. This property overwrites the value you configure in the C Series Module Properties dialog box.
Returns the conversion time setting when configured to read.
|Module ID||Returns the module ID, 0x7705.|
|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.
