Via RSLinx, establish communication. Then in RSLogix 500, click CommsSystem Comms → select your processor → Download. After download, switch the PLC from PROG to RUN mode.


Note: The newer Micro800 series uses Connected Components Workbench (CCW) , not RSLogix 500.

You can password‑protect individual program files or the entire project. However, remember that many password recovery tools exist – security is modest at best.

Unlike tag‑based systems where every variable is custom‑named, RSLogix 500 uses a structured file memory system: | File Type | Function | Example | |-----------|----------|---------| | O0 | Outputs | O:0/0 (physical output point) | | I1 | Inputs | I:1/2 | | S2 | Status | S:4 (processor status) | | B3 | Binary | B3:0/5 (internal relay) | | T4 | Timers | T4:0.ACC, T4:0.DN | | C5 | Counters | C5:0.ACC | | R6 | Control | R6:0 (for sequencers) | | N7 | Integer | N7:5 | | F8 | Float | F8:2 | Via RSLinx, establish communication

This structure can feel restrictive at first, but it forces discipline and makes memory usage highly predictable.

A typical workflow in RSLogix 500 involves the following steps: Note: The newer Micro800 series uses Connected Components

  • Verify: Click "Verify Project" to check for syntax errors.
  • Download: Connect via RSLinx and download the program to the PLC.
  • Run: Switch the PLC from "Program" mode to "Run" mode.
  • RSLogix 500 is a 32‑bit Windows application developed by Rockwell Automation. It provides a complete programming environment for Allen‑Bradley’s SLC 500 and MicroLogix families of PLCs. The software supports all five IEC‑61131‑3 programming languages that these platforms allow, with ladder logic (LAD) being the overwhelmingly dominant language.

    RSLogix 500 replaced the older DOS‑based programming software (APS, or Advanced Programming Software) and introduced a user‑friendly, mouse‑driven interface, drag‑and‑drop editing, and powerful search and diagnostic tools. Over the years, Rockwell released several versions (from 1.00 to 12.00), with later versions adding Windows 10 support, improved tag databases, and better communication configuration.


    In the world of industrial automation, few names carry as much weight as Allen‑Bradley (a brand of Rockwell Automation). For decades, their line of Programmable Logic Controllers (PLCs) has been the backbone of manufacturing floors, assembly lines, and process control systems. At the heart of programming these iconic machines lies a piece of software that became an industry standard: RSLogix 500.

    Whether you are a fresh automation technician, a maintenance electrician moving into controls, or an engineer looking to modernize legacy gear, understanding RSLogix 500 is not just a skill—it is a necessity. This article dives deep into what RSLogix 500 is, which PLCs it supports, its core features, how it compares to modern software, and why it remains relevant today.
