CHAPTER 12: HIGH SPEED I/O (HSC / PWM)
12.1 Overview
In addition to the compliment of simple analog and digital I/O, several of the XLE/XLT I/O
modules support High Speed Counting (HSC) I/O functions and may also support Pulse Width
Modulation (PWM) Output functions. The HSC functions include frequency, totalizing, pulse
width, and quadrature measurement. The PWM functions include traditional PWM (with
variable rate and duty) and a stepper (limited functionality) with variable acceleration and
deceleration rates. To determine function availability, refer to the associated model’s
Specification/Installation sheet (Digital DC Input/Output sections).
This chapter describes the operation of these high level I/O functions. For configuration
details of these functions, see Cscape Configuration (Chapter 15).
