Preface
About This Publication This document serves as a guide for replacing your existing MicroLogix™ 1000,
MicroLogix 1100, or MicroLogix 1200 controller with a Micro800™ family of
controllers.
The Micro800 family of controllers includes the Micro810®, Micro820®,
Micro830®, Micro850®, and Micro870® controllers.
Descriptions, wiring diagrams, dimensions, features, and specifications of the
controllers are provided to help you select the appropriate Micro800 controller to
replace your MicroLogix controller.
This document shows you how to use the software tools to select a suitable
Micro800 controller, and also how to convert your MicroLogix programs to work
with the Micro800 controller.
Audience The intended audience of this document is owners of MicroLogix 1000,
MicroLogix 1100, and MicroLogix 1200 controllers who are migrating to the
Micro800 family of controllers, and who are familiar with the RSLogix 500®/
RSLogix™ Micro programming software. Knowledge of programming in ladder
language is expected to be able to program Micro800 systems effectively.
Required Software To complete the steps in this document, Connected Components Workbench™
software version 12 or later is required. As the main programming software for
Micro800 systems. Connected Components Workbench software provides a
choice of IEC 61131-3 programming languages (ladder diagram, function block
diagram, structured text) with user-defined function block support that
optimizes machine control.
You need Connected Components Workbench software to write your ladder
diagram, function block diagram, or structured text programs, to execute the
programs, and to see the results.
This document uses two features that are available in Connected Components
Workbench software version 12 or later.
• MicroLogix to Micro800 Converter tool
The MicroLogix to Micro800 Converter tool converts an RSLogix 500/
RSLogix Micro project into a Connected Components Workbench
project. It provides conversion for ladder diagram (LD) programming
languages in the MicroLogix processor.

6Rockwell Automation Publication 2080-RM002B-EN-E - June 2019
Preface
The onverter tool can convert most RSLogix 500/RSLogix Micro
instruction blocks. However, you may need to modify the converted
function blocks to confirm that they work properly. All information that
requires additional modifications are logged in a conversion report, and
this document shows you how to make the changes.
• Micro800 Simulator
The Micro800 Simulator can be used to perform testing and
troubleshooting of a Connected Components Workbench project,
without a physical Micro800 controller.

Chapter 1
Micro800 Controller Overview
Micro800 controllers are designed for low-cost, standalone machines. These
economical small-size programmable logic controllers (PLCs) are available in
different form factors based on the number of I/O points that are embedded in
the base, with a range of features that are intended to address different
requirements. The Micro800 family shares programming environment,
accessories, and plug-ins that allow machine builders to personalize the controller
for specific capabilities.
Micro810 controllers function as a smart relay with high current relay outputs,
but with the programming capabilities of a micro PLC. The Micro810
controllers come in a 12-point form factor.
Micro820 controllers are designed for smaller standalone machines and remote
automation projects. They have embedded Ethernet and serial ports and a
microSD™ slot for data logging and recipe management. These controllers come
as 20-point form factors that can accommodate up to two plug-in modules. They
also support the Micro800 Remote LCD (2080-REMLCD) module for easier
configuration of settings such as IP address. The Remote LCD module can also
function as a simple IP65 text display.
Micro830 controllers are designed for standalone machine control applications.
They have flexible communications and I/O capabilities with up to five plug-ins.
They come in 10-, 16-, 24-, or 48-point form factors.
Micro850 expandable controllers are designed for applications that require more
digital and analog I/O or higher performance analog I/O. They can support up
to four expansion I/O. Micro850 controllers include additional communication
connection options through an embedded 10/100 Base-T Ethernet port.
Micro870 controllers offer machine builders and end users a higher level of
scalability, flexibility, and customization. Designed for large standalone machine
applications, the Micro870 controller comes with great memory capacity to
enable more modular program and use of user-defined function blocks. They can
support up to eight expansion I/O.
Several Micro830, Micro850, and Micro870 controllers support basic
positioning through embedded pulse train outputs (PTO). These controllers also
allow you to configure up to six high-speed counters (HSC), and choose from
nine HSC operation modes. HSC is supported on all Micro830, Micro850, and
Micro870 controller catalogs, except on 2080-LCxx-xxAWB. PTO is only
supported on Micro830, Micro850, and Micro870 controller catalog numbers
that end in BB or VB.
