Page 6: Digital I/O
The PXIe-6509 provides 96 lines of bi-directional DIO signals, P<0..11>.<0..7>. You can configure the PXIe-6509 for digital input (DI) and digital output (DO) on a line-by-line basis and use each of the DIO lines as a static DI or DO line. All samples of DI lines and updates of DO lines are software-timed. -

DAQ device or connecting to it. I/O Pull-Up/Pull-Down Resistors The PXIe-6509 has user-configurable pull-up and pull-down resistors. The DIO lines on the PXIe-6509 are connected to an NI ASCI that contains a weak pull-down resistor (47 kΩ, typical), and each DIO line is connected to a software-selectable strong pull-up... -

Industrial DIO Features Digital Filtering Use the digital filter option available on the PXIe-6509 input lines to eliminate glitches on input data. When used with change detection, filtering can also reduce the number of changes to examine and process. -
Page 11: Digital Filtering Example
You can enable digital filtering on as many input lines as necessary for your application. The PXIe-6509 supports three timing intervals: 160 ns, 10.24 µs, and 5.12 ms. Internally, the digital filter uses two clocks: a sample clock and a filter clock. The filter clock is generated by a counter and has a period equal to one half of the specified timing interval. -

(ADEs). Change Detection You can program the PXIe-6509 to send an interrupt when a change occurs on any input line. The PXIe-6509 can monitor changes on selected input lines or on all input lines. It can monitor for rising edges (0 to 1), falling edges (1 to 0), or both. -
Page 13: Watchdog Timer
In this example, the PXIe-6509 reports rising edges only on bit 1, falling edges only on bit 0, and rising and falling edges on bits 7, 6, 5, and 4. The PXIe-6509 reports no changes for bits 3 and 2. After receiving notification of a change, you can read the port to determine the current values of all eight lines. -
