# Automation and Control

## Scope
Automation and control work covers industrial automation, PLC architecture, HMI structure, alarms, diagnostics, machine integration, and logic structure across the production process.

## Core Areas
- PLC logic organized around real process stages
- deterministic control loops, interlocks, and sequencing
- HMI design for operator understanding and response
- alarm and fault logic with useful context
- diagnostics and traceability
- integration across feeders, extrusion, utilities, and downstream systems
- signal structure that supports monitoring and future analytics

## Engineering Emphasis
The emphasis is stable, traceable, and understandable process behavior. Control systems should support operators, maintenance, and engineering rather than act as opaque machine software.

## Operational Value
The result is clearer control behavior, easier diagnosis, stronger line coordination, and a better base for future industrial intelligence layers.
