Real-World Scenario Recommendations
See how RSLogix 500/5000 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
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...
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.)
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...
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
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...
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
