AutoCode is a structured, table-driven machine programming language running natively on the UniStream PLC. It transforms the controller from a device-level PLC into a complete machine operating system. What makes it fundamentally different:

• Device-level abstraction: Every connected device—motors, actuators, robots, vision systems, sensors, pneumatics—is treated as a modular object with defined methods and properties, configured through structured tables rather than ladder logic or function blocks.
• 26-command machine language: A standardized command set covering motion sequences, process control, safety interlocks, quality checks, conditional logic, and inter-device coordination—a deterministic, real-time execution engine running directly on the UniStream PLC.
• Web-server enabled: Leveraging the UniStream’s built-in web server, AutoCode delivers sophisticated operator interfaces, real-time production dashboards, remote diagnostics, and machine configuration tools—all accessible through any standard browser on any device.
• Offline and field-serviceable: Programs can be created and edited in standard spreadsheet format, uploaded directly to the controller, or modified at the machine—no proprietary development environment or internet connection required.

Multi-device coordination: AutoCode natively manages complex interactions between robots, gantry systems, conveyors, vision systems, and process equipment through its built-in device abstraction layer.

The AutoBlocks motion system is a fully integrated 6-axis robot controller managed entirely through AutoCode. The system supports up to 6 primary axes—each configurable as linear or rotary—plus 4 additional auxiliary axes, giving machine builders the flexibility to address everything from simple single-axis positioning to complex multi-axis gantry and robotic systems.

AutoCode provides a table-based programming model with G-code equivalent commands for motion programming, along with integrated jog and teach functions, axis configuration, work offsets, and recipe-driven motion profiles—giving integrators and machine builders a clean, scalable motion system they can configure and deploy without specialized motion control expertise.

Because AutoCode controls the machine directly, production data is captured at the source—automatically and in real time. The platform provides built-in data tracking and traceability capabilities designed to support MES-level production data capture and the documentation demands of regulated industries such as aerospace and medical device manufacturing.

AutoCode captures cycle data, process parameters, operator actions, and pass/fail results as a natural part of program execution. The platform supports part-level traceability—linking individual units to process conditions, recipes, and machine state—as well as quality gate enforcement and operator tracking. Because AutoCode is the machine’s execution engine, this data originates within the control system itself. There is no need for separate data collection hardware or middleware—the UniStream’s processing and storage capabilities handle data capture, logging, and delivery to external systems natively.

UniStream controllers in every AutoBlocks machine are pre-configured through AutoCode to handshake with connected equipment, managing start/finish sequences, safety protocols, and pneumatic operations automatically.

The AutoBlocks platform allows engineers and integrators to design and deploy a machine by:

• Selecting the machine architecture: gantry, robotic cell, rotary station, linear transfer, or desktop process system.
• Adding robot integration blocks—pre-configured through AutoCode for plug-and-play operation with no communications programming.
• Customizing with AutoBlocks Application Kits for robotic soldering, screw driving, induction heating, vision inspection, material handling, and more.
• Adding accessories: light curtains, vision systems, safety interlocks, and additional sensors.
• Configuring the entire machine through AutoCode’s table-driven interface—process parameters, motion profiles, quality checks, and operator workflows—without writing code.

Automatic, Transparent Communications

AutoCode manages all communications between platform modules, kits, and accessories via Modbus TCP, digital I/O, and analog communications. Engineers never configure protocols—AutoCode handles device discovery and data exchange natively.

Universal Machine Architecture

The same Control Block, AutoCode environment, and operator interface can power a desktop brazing station, a twin-table robotic soldering cell, a 25-foot gantry system, or a high-speed PCB router. This standardization dramatically reduces engineering time and makes every machine easier to support and maintain.

Plug-and-Play Robotics and Process Equipment

Robots, motors, actuators, sensors, pneumatics, vision systems, and process equipment integrate into any AutoBlocks machine through pre-configured AutoCode device profiles that manage handshaking, coordination, and safety interlocking automatically.

No Programming Required

Machine builders and integrators configure machines through parameter selection rather than code writing. AutoCode manages motion profiles, station sequences, part tracking, recipe management, and operator workflows—all configurable through the web-client HMI or standard spreadsheet upload.

Sophisticated Operator Interface

AutoCode provides operators with an intuitive, browser-based interface for machine operation: program selection, speed and acceleration control, process parameters, recipe management, alarm handling, production monitoring, and diagnostics—accessible from any display on the network, without requiring training on PLC software.

Secure, Scalable Development

The AutoBlocks team built the entire AutoCode platform using Unitronics’ free UniLogic programming software, leveraging the UniStream’s web-server capabilities for browser-accessible interfaces and data services. The architecture safeguards AutoBlocks’ intellectual property while allowing customers to configure new functions and extend machine capabilities through AutoCode’s structured API.

The AutoBlocks platform has been deployed across a diverse range of production machines, all on the same UniStream + AutoCode architecture:

• Robotic Hot Solder Dip Systems: Multi-axis robotics, thermal process control, and production traceability for aerospace-grade soldering.
• Gantry Pick-and-Place Systems: Precision multi-axis motion with machine vision for electronics assembly and material handling.
• PCB Routers: High-speed spindle motion, robotic handling, and vision-guided routing in single or twin-table configurations.
• Induction Brazing & Curing Systems: Controlled energy delivery with integrated motion, pneumatic actuation, and process recipe management.
• Semi-Automated Desktop Stations: Operator-guided systems combining manual loading with automated process control.
• OEM Equipment Integration: AutoBlocks controllers embedded directly into third-party industrial products.

AutoCode transforms the Unitronics UniStream PLC into a universal machine platform—a structured, deterministic environment where machines are configured rather than coded, where every device speaks a common language, and where the gap between machine control and production data disappears entirely. AutoCode’s 26-command machine language, device abstraction architecture, and web-enabled operator interface make the AutoBlocks platform a new standard for modular machine automation.

With Unitronics controllers at the foundation, AutoBlocks gives engineers the ability to handle virtually any production process: dispensing, screw driving, press fit, induction heating, soldering, ultrasonic welding, leak testing, inspection, assembly, heat staking, laser marking, laser welding, laser cutting, machining, and more—all on a single, unified platform.
