In Episode 220 of Manufacturing Hub, we welcome back Caleb Flanigan to explore one of the most critical yet least understood topics in the evolution of smart manufacturing: MTP (Module Type Package), MCP (Machine Context Protocol), and how they are becoming essential enablers of safe and scalable AI adoption on the factory floor.

Throughout this deep-dive episode, we uncover how these emerging standards form the backbone of adaptive plants: facilities capable of safely orchestrating decisions between humans, machines, and AI models. From OPC UA and AutomationML to edge computing and LLM-driven control systems, Caleb explains the architecture, mindset shifts, and implementation considerations that make this vision a reality.

Key topics covered include:

Why traditional SCADA and MES architectures are not AI-ready
The real-world value of MTP in legacy Brownfield plants
How Siemens’ Machine Proxy App and OPC UA servers act as translators between AI models and legacy PLCs
Differences between machine states, control interfaces, and orchestrated services in modular manufacturing
Why CLI skills and edge computing are foundational for the modern control engineer
How to pitch digital transformation and AI investments to hesitant executives

We also touch on organizational psychology, how internal champions get ignored without executive alignment, and the grim future for manufacturers still betting on ice cube relays.

Whether you’re a plant engineer, systems integrator, or digital transformation leader, this conversation offers a bold but practical look at how to safely integrate AI into manufacturing control environments: starting with protocols and principles, not just hype.
