Auto-syncing PLC tag maps with version control
TL;DR
Desktop app for PLC engineers in manufacturing plants that auto-generates, syncs, and version-controls I/O tags in TIA Portal projects by parsing existing code and linking them to physical I/O points so they can reduce tag-related commissioning errors by 70% and cut weekly tag management time from 5+ hours to under 1 hour
Target Audience
PLC engineers in manufacturing and process automation, 2-50 employees, using TIA Portal daily
The Problem
Problem Context
PLC engineers use TIA Portal daily to manage machines with physical I/O. They assign tags manually to Data Blocks or UDTs, but this becomes unmanageable as projects grow. Changes to I/O (e.g., moving cables) force them to redo tag assignments, wasting hours and causing errors.
Pain Points
Manual tagging is slow and error-prone. UDTs show raw memory addresses, making tags hard to read. Data Blocks scatter tags across projects, confusing teams. Diagrams and tag lists don’t match logic, leading to mistakes during commissioning or troubleshooting.
Impact
Teams lose 5+ hours/week fixing tag errors. Downtime from misconfigured I/O costs factories thousands per incident. Engineers waste time searching for tags or explaining changes to colleagues. Projects slow down during commissioning, delaying revenue from new machines.
Urgency
Factory changes happen daily—loose wires or tag errors can break entire systems. Engineers need a fast, safe way to update tags without risking mistakes. Current methods (manual typing, UDTs) can’t keep up, making the problem unsustainable for growing projects.
Target Audience
PLC programmers, automation technicians, and industrial engineers in manufacturing, food processing, and packaging. Teams of 3–50 engineers managing 10+ machines with frequent I/O changes. Consultants who work across multiple client sites also face this problem.
Proposed AI Solution
Solution Approach
TagSync Pro is a desktop app that auto-generates, syncs, and visualizes I/O tags in TIA Portal projects. It replaces manual UDT/Data Block work with a centralized database, reducing errors and saving time. Engineers import their TIA projects, and the tool parses tags to create a searchable, version-controlled map.
Key Features
- Version Control: Track changes over time (e.g., ‘Who moved DB
- DBW2 on 5/15?’) to audit tag history.
- Visual Mapping: Drag-and-drop diagrams link tags to physical I/O (e.g., ‘PLC Input 4 → Motor Start Button’) for clarity.
- Team Sharing: Export/import tag databases to sync changes across engineers without emails or spreadsheets.
User Experience
Engineers import their TIA project once, then use TagSync Pro to manage tags. The app shows a clean, searchable list of all tags with their addresses and linked I/O. Changes are logged automatically, and diagrams update in real time. Teams share databases via file export, ensuring everyone sees the latest tags.
Differentiation
Unlike UDTs (hard to read) or Data Blocks (scattered), TagSync Pro provides a single, searchable source of truth for tags. It’s faster than manual work and more reliable than spreadsheets. No competitors exist—Siemens ignores this gap, and free tools don’t solve the problem at scale.
Scalability
Starts with single-user licenses ($50/mo), then scales to team seats ($100+/mo per user) as firms grow. Add-ons like *advanced version control- or API integrations (e.g., PLC simulators) can increase revenue per user over time.
Expected Impact
Teams save 5+ hours/week on tag management. Fewer errors mean faster commissioning and less downtime. Engineers spend more time testing machines and less time fixing tag mistakes. Factories reduce revenue loss from misconfigured I/O.
