National Instruments PCI-6511 Digital I/O Device

The PCI-6511 (Part Number: 778966-01) comes with watchdogs. The advanced outputs go to a protected recuperation state when a mistake condition is identified and the watchdog clock terminates. Watchdogs are essential when the gadget is associated with actuators, including pumps, valves, engines, and transfers. The advanced I/O gadget screens the product application. If the application neglects to react inside the time restraint, the gadget naturally sets the output lines to a client characterized safe state. The gadget stays in the watchdog state until the watchdog clock is incapacitated by the application and new I/O esteems are composed, the NI PCI-6511 is reset, or the PC is restarted. NI computerized I/O watchdogs give security against a wide assortment of mistake conditions: PC crash, add up to OS crash, application crash (programming application stops to react), driver crash (gadget driver stops to react), or PCI bus failure (communication stop to react). 

With change identification, the user can consequently trigger their product application to play out an advanced read activity upon a computerized change of state. A computerized change of state is characterized as the rising edge (0 to 1 progress) or falling edge (1 to 0 progress) on at least one advanced lines. Utilizing NI-DAQmx programming innovation, a NI PCI-6511 advises the product application when the occasion is identified, making the application consequently play out a read task. To limit the impacts of uproarious information lines, the user can utilize programmable information channels and change recognition to take out misleading change discovery occasions caused by clamor or glitches. NI-DAQmx additionally incorporates multithreaded gushing innovation so computerized change identification occasions can happen freely of other information procurement exercises, such as simple info or output events.
