From Machine Requirements to PLC Logic in Minutes
Unitronics brings artificial intelligence directly into PLC development with Unitronics UniLogic AI. The new AI functionality helps engineers turn machine requirements into PLC logic in minutes, review and modify existing code, generate documentation, and even adapt third-party code—all within the familiar UniLogic development workflow.
AI Has Arrived in UniLogic
UniLogic is the all-in-one software environment for programming Unitronics UniStream PLCs, integrating PLC logic, HMI, I/O, motion, VFDs and communication configuration in a single platform.
With the introduction of AI, Unitronics takes PLC development a step further. Instead of writing IEC 61131-3 Structured Text (ST) logic line by line, engineers can start by defining what the machine needs to do.
The AI Wizard guides the user through questions about the application, control method and I/O, then automatically creates a detailed, UniLogic-aware prompt based on the existing project context and tags. This can be used with leading AI models such as ChatGPT, Claude and Gemini.
The result: significantly less manual coding and a much faster path from machine requirements to functional PLC logic.
What Can You Do with UniLogic AI?
The new AI capabilities support several key stages of PLC application development:
- Generate Logic – Turn machine requirements into Structured Text logic in minutes.
- Review Code – Let AI analyze your logic and identify potential issues.
- Modify Existing Logic – Update, extend or adapt code already used in your project.
- Generate Documentation – Automatically create comments and documentation while developing the application.
- Port Code – Adapt third-party IEC or other logic for use in UniLogic.
Generated logic remains under the engineer’s control: it can be reviewed, adjusted and tested before being deployed to the machine.
Up to 80% PLC Coding Time with UniLogic AI
UniLogic AI is designed for faster AI-assisted PLC programming without forcing engineers to adopt a completely new development environment or become experts in prompt engineering.
The new functionality can provide:
- up to 80% less coding time,
- machine requirements transformed into PLC logic in minutes instead of days,
- greater productivity for junior engineers from day one.
The objective is simple: spend less time on repetitive coding and more time on engineering, optimization and solving the actual automation task.
One Environment for the Complete Automation Project
AI expands an already comprehensive UniLogic engineering environment. UniLogic enables users to configure hardware and industrial communication, create Ladder and C logic, implement servo motion, design HMI screens and web pages, manage alarms and recipes, visualize trends and gauges, and integrate IIoT and cloud technologies.
The software also supports industrial and IT communication technologies such as EtherNet/IP, EtherCAT, MODBUS TCP/RTU, CANopen, BACnet, MQTT, OPC UA, SQL, FTP, SNMP and REST API.
Reusable Ladder blocks, HMI screens, web pages and tags further reduce development time by allowing engineers to build proven functionality once and reuse it across projects.
UniLogic software and its updates are available free of charge from Unitronics.
