Hey there! I totally get your frustration with the 'it depends' answers. Let me break down some concrete decision criteria for your $50k budget and small production line:
1. Learning Curve
• Mitsubishi FX5U: Japanese-style programming that's more intuitive and easier for beginners to grasp
• Siemens S7-1200: More powerful but steeper learning curve - better if you have some programming background
2. Cost Breakdown
• Mitsubishi software: $1,000-$5,000 range
• Siemens software: $1,500-$15,000 (more expensive but often more powerful)
• Hardware costs are comparable, but Siemens might have better long-term value
3. Market Presence & Support
• Mitsubishi: Strong in Asian markets, great for simpler applications
• Siemens: Global standard, better for complex tasks and future expansion
4. My Recommendation for Beginners
For your first small production line with a $50k budget, I'd lean toward Mitsubishi FX5U if:
• You're completely new to PLC programming
• Your production line is relatively simple
• You want to get up and running quickly
Choose Siemens S7-1200 if:
• You plan to expand significantly in the future
• You need to integrate with other industrial systems
• You have some technical background and can handle the learning curve
With $50k, you have room for either system. The key question is: do you prioritize ease of learning now (Mitsubishi) or scalability for the future (Siemens)?
