Eclipse 4diac vs PlatformIO IDE

Eclipse 4diac is free software for developing with IEC 61499 function blocks and C++. It runs on Linux, macOS, and Windows and includes firmware debugging. The environment supports protocols including OPC UA, OPC DA, HTTP, MQTT, RS232 serial, FMI, TSN, FBDK/IP, Modbus, openPOWERLINK, and Arrowhead. Listed 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. The deployment scope also names PLCs and embedded devices. This gives developers a free environment with named language support, communication protocols, hardware options, and runtime targets. Desktop use spans the three listed operating systems, while deployment options extend into embedded and industrial environments. Eclipse 4diac is available from the project website at eclipse.dev/4diac.
