Real-World Scenario Recommendations
See how RSLogix 500/5000 and GX Works3 perform in specific industry scenarios to help guide your decision.
Small Machine Builder
OEM building compact machines with 50-200 I/O points, typically for niche markets or specialized applications
RSLogix 500/5000
Legacy platform, but potentially viable for budget-conscious small OEMs targeting North American markets with older infrastructure. RSLogix 500 with MicroLogix hardware can cost significantly less than Studio 5000 with ControlLogix ($1,000-$5,000 vs $10,000-$30,000). If your machines have modest I/O counts (under 256 points) and don't require advanced features, MicroLogix may suffice. The installe...
GX Works3
Sweet spot for small Asian and European OEMs. GX Works3 licensing ($1,000-$5,000) is affordable enough that you can license 2-3 seats without breaking the bank. Mitsubishi's iQ-R and FX5 series offer excellent performance at competitive prices. The learning curve is gentle (1-3 months) - your programmer can be productive quickly, accelerating time-to-market. The software runs smoothly on modest ha...
Key Considerations:
- •Per-machine software licensing cost vs expected production volume
- •Time-to-market pressure - can you afford 6+ month learning curves?
- •Target customer geography and brand preferences
- •Hardware cost optimization - some platforms offer cheaper controllers
Automotive Tier 1 Supplier
Tier 1 automotive supplier providing systems and components directly to OEM vehicle manufacturers (VW, BMW, GM, Ford, Toyota, etc.)
RSLogix 500/5000
Obsolete for new automotive production lines. While MicroLogix PLCs are still produced, Rockwell is clearly phasing this out. Automotive production lines have 15-20 year lifecycles - starting new designs on sunset platforms is risky. The only justification: Cheap expansions of existing RSLogix 500-based lines where full system replacement isn't economically viable. For greenfield automotive projec...
GX Works3
Increasingly common for Asian automotive Tier 1 suppliers, particularly those serving Japanese, Korean, and Chinese OEMs (Toyota, Honda, Nissan, Hyundai, Geely, BYD). Mitsubishi Electric has strong presence in Asian automotive manufacturing, and many OEMs specify or prefer GX Works3. The licensing cost ($1,000-$5,000) is significantly lower than Siemens/Rockwell - attractive for cost-sensitive mar...
Key Considerations:
- •Customer-specified platforms are non-negotiable - verify before any engineering investment
- •Long-term parts availability (15-20 years) is critical for automotive
- •Safety certifications (SIL 2/SIL 3) must be well-established and accepted
- •Customer's plant maintenance teams must be trained on your platform
Process Industry (Chemical, Oil & Gas, Pharma)
Continuous process control in chemical plants, refineries, pharmaceutical manufacturing, and other process industries requiring high reliability and regulatory compliance
RSLogix 500/5000
Obsolete for new process plants. Some older chemical or water treatment plants have legacy RSLogix 500/PLC-5 systems requiring maintenance, but starting new process designs on sunset platforms is unacceptable. Process plants have 20-30+ year lifecycles - legacy platforms won't have adequate support. For greenfield process projects, use Studio 5000/PlantPAx. For retrofits of existing RSLogix 500 sy...
GX Works3
Limited adoption in Western process industries, but more common in Asian process plants. Mitsubishi has process automation solutions, but market penetration is lower than Siemens or Rockwell in critical process applications. The reliability and features are adequate, but the ecosystem of process field instruments, safety systems, and SCADA integrations is less developed. For non-critical process a...
Key Considerations:
- •Redundancy and high availability are mandatory for critical processes
- •Safety certifications (SIL 2/SIL 3) for emergency shutdown systems
- •Long-term vendor support (20-30 year plant lifecycles)
- •Integration with process instrumentation and field devices
