each write/read access, and for each accessor. It is possible to have a local real-time VI running on the controller which concurrently accesses a different set of clusters without interference, and piping data from one cluster to another can allow data to flow between this real-time VI and a PC VI efficiently and with quite low latency.
200:
The Linux Real-Time OS running in the real-time controller supports a filesystem and hence data logging is also available at the controller level. The Full
Development System version of LabVIEW does not come with the modules needed to program the cRIO. The Real-Time Module and FPGA Modules have to be
219:
Data can also be piped though 'FPGA to HOST' and 'HOST to FPGA' DMA fifos, which also work over the network interface. Each VI having an interface, each host FIFO connection and each IRQ connection all count as accessors to the FPGA hosted by the controller. These FIFO's can typically saturate the
215:
Do note that the read/write interface block appears to package multiple accessors into one, but actually loops with a round-trip delay per additional access added, which can very quickly add up. This can be worked around by grouping all controls into one cluster, and all displays into another, for

Other examples of applications areas are: Intelligent
Systems for the Industrial Internet of Things (IIoT), Power Electronics and Inverter Control, Condition Monitoring of Rotating Equipment, Power Quality Monitoring, Transportation and Heavy Equipment, and Laser or Hydraulic Control.
211:
It is not necessary to run a real-time VI on the controller in order to run the FPGA VI, as the LabVIEW FPGA interface is network capable, supporting up to 7 concurrent accessors. This is done with a connection URL like RIO://ip/RIO0
