That's a really insightful question about where industrial automation is headed! From what I'm seeing in the industry, we're definitely moving toward a transformation, but it's more of an evolution than a complete replacement.
PLCs aren't likely to become just 'dumb terminals' anytime soon. Instead, they're evolving into smarter, more integrated systems. Edge AI is being added to PLCs to enhance their capabilities, not replace them entirely. Think of it as PLCs getting an AI-powered upgrade rather than being made obsolete.
For traditional ladder logic programmers, this means your skills are still valuable but will need to expand. You'll be working with:
1. Hybrid systems where ladder logic handles real-time control while AI manages predictive analytics
2. Edge controllers that combine PLC functionality with AI capabilities
3. New programming approaches that blend traditional control logic with data science concepts
The good news is that by 2026, over 60% of new production lines are expected to use AI edge controllers, so there will be plenty of opportunities for programmers who can bridge both worlds. Your understanding of industrial processes and control logic gives you a solid foundation to build on as you learn AI integration skills.
