Eclipse 4diac
What it is
Eclipse 4diac is free software for working with IEC 61499 function blocks and C++. It runs on Linux, macOS, and Windows and includes firmware debugging. Its named protocol support covers OPC UA, OPC DA, HTTP, MQTT, RS232 serial, FMI, TSN, FBDK/IP, Modbus, openPOWERLINK, and Arrowhead. Supported boards include Raspberry Pi, BeagleBone Black, PLC01A1, Revolution Pi, Wago PFC200, PiFace Digital 2, µMIC.200, Bosch Rexroth PLC, and Lego Mindstorms EV3. Deployment targets include Windows and Linux, including ARM systems, plus NetOS, eCos, rcX, vxWorks, and freeRTOS. This gives developers a single free environment spanning desktop operating systems, industrial controllers, and embedded hardware. The combination of IEC 61499 function blocks, C++, firmware debugging, protocol options, and named boards supports projects that need to move between development computers and varied runtime targets. The project website is eclipse.dev/4diac.
