A Practical Guide to Creating a 'Digital Twin' for Your Existing Equipment

The term "Digital Twin" is everywhere in manufacturing and industry circles. It often conjures images of complex 3D simulations and multi-million dollar software suites, putting it out of reach for most small to medium-sized enterprises (SMEs).

But what if we stripped away the hype?

For the Maintenance Manager on the factory floor, a Digital Twin doesn't need to be a metaverse-ready 3D model. Its real value is much simpler and more practical: it’s a single source of truth for a physical asset, accessible instantly, by anyone on your team.

A practical Digital Twin answers three simple questions when a machine faults at 2 AM:

1. What is this machine?
2. What has been done to it in the past?
3. How is it supposed to be configured right now?

Building this doesn't require a team of data scientists. It requires a structured approach and the right tools. Here is a no-nonsense, 5-step guide to start creating practical Digital Twins for your most critical equipment.

Step 1: Identify Your "Critical Few"

Don't try to boil the ocean. You don't need to digitize every single machine in your facility. Start with the Pareto principle: identify the 20% of your assets that cause 80% of your downtime and headaches.

This is usually the "hero" equipment: the main conveyor on the packaging line, the primary boiler, the glycol chiller, or that one temperamental pump that everyone is afraid to touch. Start with a list of just five to ten of these critical assets.

Step 2: Give Each Asset a Unique Identity (The Physical Link)

Your digital record needs a foolproof way to connect to the physical machine. The simplest and most robust method is a QR code.

Purchase a set of durable, industrial-grade polyester or metal QR code labels. Create a unique ID for each of your critical assets (e.g., GCS-BREW-PUMP-001) and link it to a QR code. Affix this label directly to the machine or its main control panel. This QR code is the physical key that will unlock its digital counterpart.

Step 3: Centralize the "Static" Documentation

Every machine comes with a folder of paperwork that inevitably gets lost, damaged, or ends up in the wrong filing cabinet. The next step is to digitize it.

For each asset, scan and upload:

• The User Manual
• The Electrical Schematics & P&ID Drawings
• The Commissioning Report
• Standard Operating Procedures (SOPs)
• Lockout-Tagout (LOTO) Safety Procedures

Store these in a central, cloud-based location and link them to the asset's unique ID. Now, anyone who scans the QR code can instantly access the correct manual on their phone instead of wasting 30 minutes searching the office.

Step 4: Capture the "Live" Data (The Golden Link)

This is the most crucial step and the one most businesses miss. The static documents tell you how the machine should work, but they don't tell you how it's actually configured right now. This is where you capture the "tribal knowledge."

For each asset, create a simple, version-controlled record of its software configuration. This could be:

• For a VSD: A list of its key parameters (Ramp Up, Max Frequency, S-Curve, etc.).
• For a PLC-controlled process: The name and version of the PLC program (MashTunControl_v1.2).
• For a PID Loop: The P, I, and D tuning values that your best technician spent hours perfecting.

This is the Golden Link: the connection between the physical asset and the software that makes it run. When a setting is changed, a new version is created. Now you have a running history of the asset's digital life.

Step 5: Log Every Action

Finally, every time a technician interacts with the asset, the action should be logged against its digital record. This creates a rich, searchable service history.

• Breakdown Maintenance: "Replaced motor contactor MC1." (Attach a photo of the new contactor).
• Software Change: "Updated VSD parameters to v2.1 to smooth out start-up."
• Preventative Maintenance: "Greased motor bearings as per 6-month schedule."

The "Easy Button" for Your Digital Twin Strategy

You could absolutely build this system yourself using a combination of spreadsheets, a Dropbox folder, and a separate work order system. But you'll quickly run into issues with version control, permissions, and ensuring the data is linked correctly.

This exact, practical workflow is why we built Demiton.

Our platform is purpose-built to be the "easy button" for creating practical Digital Twins:

• The Asset Register is your central hub.
• The Function Block library is designed to capture and version-control your "live" data (Step 4).
• The Job Docket logs every action against the asset, creating a perfect service history (Step 5).

It all works together, accessible from a single QR code scan.
