CompactRIO 8-Channel, 24 V, Sourcing Digital Output Module
Use the FPGA I/O Node to access the following terminals for this device.
|DOx||Digital output channel x, where x is the number of the channel. The NI 9472 has DO channels 0 to 7.|
|DO7:0||Digital port consisting of channels 0 through 7. Channel 7 is returned in the MSB, and channel 0 is returned in the LSB.|
You can configure the arbitration settings for the channels of this device in the Advanced Code Generation page of the FPGA I/O Properties dialog box. The default arbitration setting is Never Arbitrate.
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 Status||Returns a Boolean value that indicates whether the module is ready.
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.
|Module ID||Returns the module ID.|
|Serial Number||Returns the unique serial number of the module.|
|Vendor ID||Returns the NI vendor ID, 0x1093.|
When the module is within a single-cycle Timed Loop, it must be ready to perform digital output before a loop containing digital output starts. Poll the Ready output of the Check Status method to determine whether the module is ready. The module might ignore or delay digital output operations if it is not ready.
While the module is performing digital output within a single-cycle Timed Loop, do not perform property reads or remove the module from the chassis. Doing either of these actions causes the module to be unable to perform digital output and the Ready output of the Check Status method to return FALSE.
