Smelter Process Control Deployment
Where the control systems of a metal smelter run: field instruments, PLCs and a DCS in the plant, a historian, and a separate business network behind a demilitarised zone.
Deployment diagrams are part of Pro. Anyone can view this one; generating and editing it needs Pro.

What this diagram shows
- Plant control is separated from the office network
- A historian stores every process value for analysis
- Data reaches business systems only through a DMZ
Prompt used
Smelter control deployment following the Purdue model: field sensors (temperature, flow, gas) and actuators connect to PLCs and a distributed control system (DCS) at level 1 and 2. Operator stations and an engineering station sit on the control network. A process historian collects data. A DMZ holds a replicated historian and patch server, and the business network runs MES and ERP.

Mine Fleet Management System
A fleet management system for an open-pit mine: dump trucks and shovels report position and payload, a dispatch engine assigns loads, and a control room watches production live.
Haul Truck Cycle
The states of a mining haul truck in each load-and-dump cycle, used by dispatch systems to measure productivity and waiting time.
Underground Mine Communication Network
How an underground mine keeps people connected and safe: leaky feeder radio, Wi-Fi, gas sensors and personnel tracking tags, linked to the surface control room.
Ore to Metal Material Flow
How mined ore becomes finished metal in an iron and steel chain, in thousand tonnes per month, showing where material is lost.
Chemical Batch Traceability
Tables that trace a chemical product batch back to its raw material lots, process steps, quality tests and customer shipments, for recalls and audits.
Mine Blast Planning and Safety
How a mine plans and carries out a blast safely: drill pattern design, explosive loading, area clearance, the blast, and post-blast checks.
