Real-World Scenario Recommendations
See how GX Works3 and Unity Pro 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
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...
Unity Pro
Legacy Schneider platform being replaced by EcoStruxure. Not recommended for new machine designs - choose EcoStruxure instead. Unity Pro is for maintaining existing Modicon M340/M580 installations. If a customer specifically requests Modicon compatibility with legacy systems, Unity Pro may be necessary, but negotiate this carefully as it's sunset technology. The licensing cost ($1,500-$7,000) is b...
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.)
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...
Unity Pro
Legacy platform - not recommended for new automotive projects. Some European automotive plants have existing Modicon M580 installations that require Unity Pro for maintenance and expansions. If you're supporting existing lines, Unity Pro knowledge is necessary. For new projects, choose EcoStruxure instead. Don't invest in learning sunset technology unless you're maintaining specific legacy systems...
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
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...
Unity Pro
Legacy Schneider platform with significant installed base in process industries, particularly oil and gas offshore platforms, water treatment, and power generation. Unity Pro with Modicon Quantum/M580 Hot Standby provides the redundancy needed for critical processes. However, Schneider is transitioning customers to EcoStruxure. For existing Unity Pro installations, maintenance and expansions are n...
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
