Simultaneously Reading From or Writing to Multiple CompactRIO Channels (FPGA Interface)

You can simultaneously read from or write to multiple channels on a single simultaneous module such as the NI 9215, NI 9225, NI 9229, NI 9239, NI 9263, NI 9264, and NI 9265. Configure a single FPGA I/O Node with the channels you want to simultaneously sample or update. If you configure a single FPGA I/O Node with channels from different modules, FPGA I/O execution begins at the same time for all the modules, but the actual sampling or update times may differ between modules depending on the types of modules, the number of channels used on each module, the arbitration settings, and whether or not the modules are idle when the I/O Node begins execution. If you configure an FPGA I/O Node with multiple channels on a non-simultaneous module, the function accesses the channels sequentially.
