Use the High-Speed Counter
To use a HSC device, you first need to establish the HSC counting mode
required by your application. See
HSC Mode (HSCAPP.HSCMode) on page 127
for available modes on Micro800 controllers.
The following sample project guides you through the creation of a project that
uses HSC mode 6, a quadrature counter with phased inputs A and B. It shows
you how to write a simple ladder program with the HSC function block, create
variables, and assign variables and values to your function block. It also guides
you through a step-by-step process on how test your program, and enable a
Programmable Light Switch (PLS).
This sample project makes use of a quadrature encoder. The quadrature
encoder is used for determining direction of rotation and position for
rotating, such as a lathe. The Bidirectional Counter counts the rotation of the
Quadrature Encoder.
shows a quadrature encoder connected to inputs 0 and 1.
The count direction is determined by the phase angle between A and B. If A
leads B, the counter increments. If B leads A, the counter decrements.
