Specialty Digital Configuration (Scan Interface)

You can use the Specialty Digital Configuration page of the C Series Module Properties dialog box to configure some C Series digital input and output modules for specialty digital functions. Specialty digital functions include count input, counter-driven output, pulse-width modulation output, and quadrature input.

If the chassis is in Scan Interface mode, you can configure modules in up to two slots for specialty digital functions. If you want to configure more than two modules for specialty digital functions, you must change the programming mode of the chassis to FPGA Interface mode. You still use the Scan Interface for the modules that you configure for specialty digital functions.

The maximum update rate for modules configured for specialty digital functions is approximately 4 mHz.
