question

As a beginner facing a $50k automation budget, how do I choose between Siemens S7-1200 and Mitsubishi FX5U for my first small production line when everyone says 'it depends' but I need concrete decision criteria?

answer

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)?
