Comprehensive Guide to Learning PLCs
Selecting the correct edition of Studio 5000 Logix Designer (formerly RSLogix 5000) is the most critical first step in your PLC programming journey.
Choosing the wrong version can lead to unnecessary costs or, worse, software that doesn't support your hardware. This guide helps you navigate the Rockwell Software Portal to find the exact license you need for your Allen Bradley controllers.
1. Identify Your PLC Hardware Requirements
The software version you need is determined entirely by the hardware you are using.
Micro 800 Series: These controllers use Connected Components Workbench (CCW). If you are using these, you do not need Studio 5000.
CompactLogix & ControlLogix: These require Studio 5000. Within this family, your choice depends on whether you are using the small-scale CompactLogix or the high-performance ControlLogix rack-based systems.
2. Studio 5000 Edition Comparison and Selection
Rockwell Automation offers several "scaled" versions of Logix Designer. Choosing the right one can save you thousands of dollars in licensing fees.
| Edition | Best For... | Supported Controllers | Programming Languages |
|---|---|---|---|
| Service | Maintenance & Troubleshooting | Compact & ControlLogix | View-only (Upload/Download) |
| Mini | Beginners & PLC Trainers | CompactLogix Only | Ladder Logic Only |
| Light | Advanced Small Systems | CompactLogix Only | Ladder, FBD, ST, SFC, & Safety |
| Standard | General Industrial Use | Compact & ControlLogix | Ladder Logic Only |
| Full / Pro | System Integrators | Compact & ControlLogix | All Languages + Advanced Tools |
3. Critical Decision Factors for Technicians
Prioritize Ladder Logic: Over 90% of industrial applications are written in Ladder Diagram (LD). If you are just starting, the Mini Edition is the most cost-effective way to gain marketable job skills without overspending on features you won't use.
Subscription vs. Perpetual Licensing: You can find current pricing on the Rockwell Software Portal. A Subscription (annual lease) often includes 8-to-5 TechConnect Support, which is invaluable when you are stuck on a machine-down situation. Perpetual licenses have a higher upfront cost but allow you to own that specific version indefinitely.
Firmware Compatibility: Your Studio 5000 version must match the firmware version of your PLC. Modern licenses allow you to install multiple versions (v20 through v36+) to support the various generations of equipment in your facility.
4. Avoiding the "Service Edition" Trap
While the Service Edition is the most affordable, it acts as a "window" into the code rather than a tool for growth. It allows you to see the logic but limits your ability to make the meaningful changes required for troubleshooting or complex repairs. For those using a PLC Trainer, the Mini Edition is the recommended baseline for a complete learning experience.
