Hey there! That's an excellent question that every new automation engineer faces. The 'holy war' between Siemens, Rockwell, and Mitsubishi is real, but here's how to navigate it smartly:
First, understand that each platform has its strengths and regional dominance. Siemens is huge in Europe and process industries, Rockwell (Allen-Bradley) dominates North America, and Mitsubishi is strong in Asia and motion control applications. Your location and target industry matter a lot!
Instead of picking just one, I'd suggest starting with a solid foundation in PLC programming concepts that apply to all platforms. Master ladder logic, function block diagrams, and structured text - these skills transfer between vendors. Then, look at job postings in your area to see which platforms are most in demand.
For long-term career flexibility, consider learning Siemens TIA Portal first - it's more accessible with free trial versions, and Siemens has a strong global presence. But if you're in North America, Rockwell Studio 5000 experience will open more doors locally.
Remember, the best automation engineers understand multiple platforms. Start with one, get really good at it, then expand your skillset. The core concepts are what truly matter for a decades-long career, not just brand loyalty!
