IEC 61499 Runtime Environment

The 4DIAC runtime environment (4DIAC-RTE, FORTE) is a small portable implementation of an IEC 61499 runtime environment targeting small embedded control devices (16/32 Bit), implemented in C++. It supports online-reconfiguration of its applications and the real-time capable execution of all function block types provided by the IEC 61499 standard.

FORTE supports all IEC 61131-3 edition 2 elementary data-types, structures, and arrays. It provides a scalable architecture which allows FORTE to adapt to the needs of your application. Applications can consist of any IEC 61499 element as basic function blocks (BFBs), composite function blocks (CFBs), service interface function blocks (SIFBs), adapters and subapplications. For connections between function blocks FORTE uses automatic and save castings (e.g., INT -> REAL). FORTE provides a flexible communication infrastructure via so called communication layers.
