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).
To configure the plug-in module, you need to download and use the
HSC UDFBs from the Sample Code Library:
http://www.rockwellautomation.com/go/scmicro800
From Connected Components Workbench Release 7.0 onwards, the
sample code is included in the installation and is located in the folder:
\documents\public documents\ccw\samples\rockwell automation\udfb
See Quickstart Projects for 2080-MOT-HSC Plug-in
on page 97 for
step-by-step instructions on how to use the plug-in with a sample
project.
From Connected Components Workbench Release 8.0 onwards,
support has been added for a HSC Feedback Axis which uses the
same instructions as the PTO Motion Axis. UDFBs are still supported
(you can use either one but you cannot select both for the same plug-
in).
From Connected Components Workbench Release 11.0 onwards,
support has been added for native HSCE instructions which can be
used in place of the UDFBs.
With native HSCE instructions, you can configure the plug-in offline
using a graphical user interface. With UDFBs, configuration is done at
runtime using instructions.
2080-MOT-HSC modules with hardware revision 1.xxx only supports a
value of one for Number of Pulses for rate calculation. 2080-MOT-HSC
modules with hardware revision 2.xxx enhances support by enabling
you to choose a value from 1...255. The hardware revision is found on
the label on the module.
