High Speed Counter – 2080-MOT-HSC
Overview The 2080-MOT-HSC plug-in module provides enhanced high speed counter
capabilities to the Micro800 controller. It supports the same functionalities of an
embedded high-speed counter on the Micro800 controllers but is enhanced to
support up to 250 KHz 5V differential line driver for improved noise immunity
and provides additional dedicated I/O.
The 2080-MOT-HSC module supports most commercial encoders (5V
differential or 24V single-ended).
Counter Specifications Filter and decode inputs: 3 input points A, B, Z
These input points may come from different types and configurations of sensors.
The user must configure the module to respond to the type of sensor connected
to the module as described below.
IMPORTANT To configure the plug-in module, you need to download and use the
HSC UDFBs from the Sample Code Library:

See Quickstart Projects for 2080-MOT-HSC Plug-in on page 84 for
step-by-step instructions on how to use the plug-in with a sample
project.
