Industrial automation is entering a new era.
Traditional factory control systems were designed around a centralized architecture where a single PLC managed an entire production line. While this approach worked well for fixed automation environments, modern manufacturing now demands far greater flexibility, scalability, and intelligence.
With the rise of:
Smart factories
Industrial IoT (IIoT)
Edge computing
AI-driven manufacturing
Distributed energy systems
AGV and robotics collaboration
…the limitations of conventional PLC architectures are becoming increasingly apparent.
This is where IEC 61499 is changing the future of industrial automation.
IEC 61499 is an international standard for distributed industrial automation systems.
Unlike IEC 61131-3, which primarily defines PLC programming languages, IEC 61499 focuses on how automation applications are structured, distributed, and executed across multiple devices.
In simple terms:
Traditional centralized PLC programming.
Distributed, event-driven industrial control architecture.
Because of its modular design philosophy, IEC 61499 is often compared to the “microservices architecture” used in modern IT systems.
In a traditional PLC system, all logic is usually tied to one controller.
IEC 61499 takes a completely different approach.
Applications are divided into independent “Function Blocks,” where each block can:
Operate independently
Exchange events over networks
Run on different physical devices
Be dynamically deployed or reconfigured
Scale across edge devices and cloud platforms
This distributed architecture enables far greater flexibility and scalability compared to conventional PLC systems.
Instead of “one PLC controls everything,” IEC 61499 enables multiple intelligent nodes to collaborate in real time.
Edge computing is becoming a core requirement for Industry 4.0.
Manufacturers increasingly need:
Real-time local decision-making
Reduced cloud latency
Lower network bandwidth usage
High system reliability
Distributed processing capabilities
IEC 61499 naturally aligns with edge computing because Function Blocks can run directly on industrial edge controllers and distributed nodes.
This allows control logic to move closer to machines, sensors, robots, and industrial equipment.
The result is:
Faster response times
Improved system resilience
Easier scalability
More flexible industrial architectures
One of the most mature open-source IEC 61499 ecosystems today is:
Eclipse 4diac (Engineering IDE)
FORTE Runtime
FORTE Runtime is optimized for:
Linux systems
ARM processors
Embedded edge devices
Industrial gateways
Distributed automation environments
This makes it highly suitable for Industrial IoT and edge control applications.
Modern distributed automation requires hardware platforms that are:
Reliable
Low power
Industrial-grade
Open and scalable
Linux compatible

Combine protocol conversion, edge analytics, and distributed automation.
Industrial control systems are rapidly evolving from closed, centralized PLC architectures toward open, distributed edge computing platforms.
IEC 61499 provides a powerful foundation for this transformation.
As Industry 4.0 adoption accelerates, distributed automation and edge intelligence will become standard requirements across manufacturing, energy, transportation, and smart infrastructure.
Industrial edge controllers based on Linux and ARM architectures are expected to play a major role in enabling this next generation of automation systems.
IEC 61499 is more than just another automation standard.
It represents a shift toward modular, scalable, distributed industrial control — much like how microservices transformed enterprise software.
Combined with edge computing platforms such as the BLIIOT ARMxy Series, IEC 61499 opens the door to more intelligent, flexible, and future-ready industrial systems.
