C Series Module Support for Specialty Digital Functions in Scan Mode

Updated Nov 17, 2022

Overview

This article discusses the specialty digital functions available for C Series Modules when configured for scan mode.

Introduction

Not all digital modules support special digital functions. 

Specialty digital functions are:

  • Counter input
  • Counter-driven output
  • Pulse-width modulation (PWM) output
  • Quadrature encoder input

The following table outlines what modules do support specialty digital and what specific functions as of CompactRIO 15.0:
