Overview

What is RSLogix 500?

RSLogix 500 is Rockwell Automation's programming software for the SLC 500 and MicroLogix families of PLCs. These are older, address-based PLCs that use a memory-file system: input file I:0, output file O:0, timer file T4, counter file C5, integer file N7. The programming model is the foundation of classic Allen-Bradley ladder logic and still runs millions of machines in industry.

RSLogix 500 is distinct from Studio 5000 (which programs the newer ControlLogix and CompactLogix tag-based platform). If your job ad or training program mentions SLC 500, MicroLogix 1200, MicroLogix 1400, or MicroLogix 1500, you need RSLogix 500. If it mentions ControlLogix or CompactLogix, you need Studio 5000.

Free version details

What RSLogix Micro Starter Lite includes — and what it does not

Included in Starter Lite (free)

  • Full ladder logic editor — contacts, coils, timers, counters, math, comparison, move instructions
  • Program MicroLogix 1000 and MicroLogix 1100 (up to 40 I/O points)
  • Upload and download to physical hardware
  • Online monitoring — watch live tag values while connected
  • Instruction Set Reference (ISR) help files
  • Save and open .RSS project files
  • No time limit, no license key, no activation required

Not included in Starter Lite

  • MicroLogix 1200, 1400, 1500 (requires full RSLogix Micro or RSLogix 500)
  • SLC 500 family (5/01 through 5/05) — requires RSLogix 500
  • RSLogix Emulate 500 for software simulation — separate paid product
  • Force I/O (forcing is a paid feature in the full version)
  • Processor fault routine programming
  • High-speed counter module configuration

Requirements

System requirements for RSLogix Micro Starter Lite

RSLogix Micro Starter Lite is Windows software. It was designed for Windows XP/7/8 but runs on Windows 10 and 11 with compatibility settings applied.

Operating systemWindows 10 (64-bit) or Windows 11 — run as Administrator, set compatibility mode to Windows 8 if issues arise
RAM2 GB minimum (4 GB recommended on Windows 10/11)
Disk spaceApproximately 500 MB
CommunicationUSB-to-serial adapter for MicroLogix 1000 (serial port); native USB or Ethernet for MicroLogix 1100
macOS / LinuxNot supported — requires Windows or a Windows VM
LicenseNone required — download directly from Rockwell's website with a free myRockwell account

Download steps

How to download RSLogix Micro Starter Lite

1

Create a free myRockwell account

Go to rockwellautomation.com and register for a free myRockwell account. You need a valid email address. This account is required to access the PCDC download portal.

2

Go to the PCDC portal

Navigate to the Rockwell Product Compatibility and Download Center (compatibility.rockwellautomation.com). Log in with your myRockwell credentials.

3

Search for RSLogix Micro Starter Lite

In the search box enter "RSLogix Micro Starter Lite". Select the product from the results and choose the current release. The download is a self-extracting executable or ZIP, typically 100–300 MB.

4

Install as Administrator

Right-click the installer and select "Run as Administrator". Accept the default installation path. If Windows displays a SmartScreen warning, click "More info" then "Run anyway" — Rockwell software is commonly flagged by SmartScreen on newer Windows versions.

5

No license activation needed

Unlike the full RSLogix 500 or Studio 5000, the Starter Lite requires no license key. After installation, launch it directly from the Start menu. If you see a "No License Found" error, verify you are running the Starter Lite version (not the full RSLogix Micro) — the full version requires a paid license.

No hardware, no Windows?

Practice SLC 500 / MicroLogix ladder logic free in your browser

RSLogix Micro Starter Lite requires Windows and ideally a physical MicroLogix controller to run programs. If you are on macOS, Linux, or Chromebook — or if you just want to practice the ladder instruction set without installing anything — our browser simulator uses the same Allen-Bradley addressing conventions and instruction mnemonics: I:0/0 inputs, O:0/0 outputs, T4:0.ACC timers, C5:0.ACC counters, N7:0 integers.

Same instruction set

XIC (Examine If Closed), XIO (Examine If Open), OTE (Output Energise), OTL/OTU (Latch/Unlatch), TON, TOF, CTU, CTD, ADD, SUB, MOV, CMP — the full SLC 500/MicroLogix instruction vocabulary.

Same address file format

I:0/0 for input bits, O:0/0 for output bits, B3:0/0 for internal bits, N7:0 for integers, T4:0 for timers, C5:0 for counters — the same memory file conventions used in RSLogix 500 projects.

Questions

RSLogix 500 free FAQ

RSLogix Micro Starter Lite is genuinely free — no credit card, no license key, no time limit. It is a restricted version of RSLogix Micro that programs only MicroLogix 1000 and MicroLogix 1100 controllers with up to 40 I/O points. The full RSLogix 500 (which programs the complete SLC 500 and MicroLogix range up to 4096 I/O points) is a paid product. The free Lite version is sufficient for learning ladder logic fundamentals on real hardware.

Allen-Bradley ladder logic — free in your browser, any OS.
