As a beginner trying to automate my first production line, how do I choose between Siemens S7-1200 and Mitsubishi FX5U PLCs when I need to control 3 servo axes and 20 I/O points, but my budget is tight and I'm worried about future scalability?

Accepted Answer

Hey there! I totally get your dilemma - choosing your first PLC for a production line can feel overwhelming, especially when you're balancing budget, performance, and future growth. Let me break down the key differences to help you decide:

For your specific needs (3 servo axes + 20 I/O), the Mitsubishi FX5U has a clear advantage in motion control. It has stronger built-in motion capabilities and tighter high-speed control integration right out of the box. The FX5U also edges ahead with faster execution speeds, which is great for handling multiple servo axes simultaneously.

On the budget side, Mitsubishi tends to be more cost-effective overall. The software (GX Works3) is also cheaper ($1,000-$5,000 vs Siemens TIA Portal's $1,500-$15,000) and easier to learn as a beginner - it typically takes 1-3 months versus 3-6 months for Siemens.

However, if you're thinking long-term scalability and ecosystem, Siemens S7-1200 integrates better with larger industrial systems and has more structured expansion options. It's part of a massive global ecosystem with extensive support.

My practical advice: Since you're a beginner with tight budget and need solid motion control, go with the Mitsubishi FX5U. It'll handle your 3 servo axes well, is more affordable, and the learning curve is gentler. You can always upgrade to Siemens later as your needs grow and budget allows!
