As industrial automation evolves toward distributed intelligence, edge computing, and interoperable systems, IEC 61499 is emerging as a key standard for next-generation control architectures.
Unlike traditional PLC systems that depend on centralized control and proprietary ecosystems, IEC 61499 is designed around event-driven execution, distributed function blocks, and device-to-device collaboration.
To fully leverage these capabilities, engineers need a hardware platform that is open, scalable, and communication-focused. This is where ARM Linux controllers such as the BLIIOT ARMxy Series and EdgePLC Series provide a significant advantage.
Traditional PLC architectures were originally designed for centralized machine control. While highly reliable, they can become costly and inflexible when systems need to scale across multiple machines, production lines, or geographically distributed assets.
IEC 61499 addresses these challenges by enabling:
• Distributed control logic
• Event-driven execution
• Device-to-device communication
• Dynamic deployment and reconfiguration
• Edge-to-cloud integration
These requirements align naturally with modern ARM Linux industrial controllers.
One of the key advantages of ARMxy and EdgePLC controllers is their Linux-based architecture.
Developers can deploy:
• FORTE Runtime
• Eclipse 4diac tools
• Docker containers
• MQTT applications
• OPC UA services
• Python and C/C++ programs
• Node-RED workflows
Unlike proprietary PLC platforms, Linux provides complete flexibility for application development, integration, and maintenance.
This openness reduces engineering effort and accelerates project deployment.
Distributed automation often requires multiple intelligent control nodes working together across a plant.
ARM-based industrial controllers offer several benefits:
Typical operating power is significantly lower than traditional industrial computers, enabling energy-efficient deployments.
ARM controllers are well suited for harsh industrial environments where reliability and maintenance-free operation are critical.
In many applications, the investment required for a single high-end PLC can support multiple ARM-based controllers, making distributed architectures more practical and affordable.
Wide-temperature operation and industrial-grade hardware ensure stable 24/7 performance in demanding environments.
Communication is at the core of IEC 61499.
BLIIOT ARMxy and EdgePLC controllers support a broad range of industrial and IT protocols, including:
• Modbus TCP
• EtherNet/IP
• Profinet
• MQTT
• OPC UA
• REST API
• Dual Gigabit Ethernet
This enables real-time communication between machines, controllers, SCADA systems, MES platforms, and cloud services.
The result is a flexible and future-ready industrial automation architecture.
To evaluate IEC 61499 deployment capabilities, a temperature and humidity monitoring application was divided into three independent function block groups.
Each group was deployed to a separate ARM-based controller.
Using Eclipse 4diac publish/subscribe communication:
• Controller A collected sensor data
• Controller B executed control logic
• Controller C handled alarms and outputs
No centralized PLC was required.
The entire application operated through collaborative edge nodes communicating in real time.
This demonstrates one of the core advantages of IEC 61499: distributed intelligence running directly at the edge.
The BLIIOT ARMxy and EdgePLC product families provide all the key capabilities required for modern distributed automation:
✔ Linux operating system
✔ ARM-based industrial hardware
✔ Open software ecosystem
✔ Industrial protocol support
✔ Edge computing capability
✔ Scalable distributed deployment
Together with Eclipse 4diac and FORTE Runtime, these platforms enable engineers to build open, flexible, and future-ready industrial control systems.
IEC 61499 is transforming the way industrial automation systems are designed and deployed.
To unlock its full potential, organizations need hardware platforms built for openness, networking, and distributed intelligence.
BLIIOT ARMxy and EdgePLC controllers combine ARM architecture, Linux flexibility, industrial connectivity, and edge computing capabilities to create a practical foundation for IEC 61499 applications.
The future of industrial automation is no longer centralized—it is distributed, event-driven, and edge-powered.
