I/O Properties
Use the FPGA I/O Property Node to access the following properties for this device.
| Property | Description |
|---|---|
| LSB Weight | Returns the LSB weight in pΩ/LSB for the channel. Use this value to convert and calibrate NI 9217 data if you set the Calibration Mode to Raw in the C Series Module Properties dialog box. |
| Offset | Returns the calibration offset in µΩ for the channel. Use this value to convert and calibrate NI 9217 data if you set the Calibration Mode to Raw 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.
| Property | Description |
|---|---|
| Conversion Time | Sets the time in milliseconds it takes to acquire conversion data. This property overwrites the value you configure in the C Series Module Properties dialog box. |
| Module ID | Returns the module ID. |
| Serial Number | Returns the unique serial number of the module. |
| Vendor ID | Returns the National Instruments vendor ID, 0x1093. |
Single-Cycle Timed Loop
This device does not support the single-cycle Timed Loop.
