IEC 61499 defines a domain specific modeling language for developing distributed industrial control solutions.
IEC 61499 extends IEC 61131-1 by improving the encapsulation of software components for increased re-usability,
providing a vendor independent format, and simplifying support for controller to controller communication.
Its distribution functionality and the inherent support for dynamic reconfiguration provide
the required infrastructure for Industrie 4.0 and industrial IoT applications.
