Correlated vs. Static DIO Modules Digital I/O module capabilities are determined by the type of digital signals that the module is capable of measuring or generating. Static digital I/O modules are designed for signals that change slowly and are accessed by software-timed reads and writes. Correlated digital I/O modules are for signals that change rapidly and are updated by either software-timed or hardware-time

PFI Signals The PFI signals, available through correlated digital input and output modules installed in slots 5 and/or 6, provide access to advanced features such as triggering, synchronization, and counter/timers. Refer to the PFI section for more information. The PFI pins have a digital filter circuit at the inputs that is configurable on a per-line basis. The filters allow the rejection of noise caused by noisy environments, bounces on switches, and so on. Flexible Counter/Timers The NI
