About Compact Logic
Ingenieurbüro Brauns develops and markets the Compact-Logic system (CL), a graphical development environment for control logic that runs as a software PLC (embedded PLC) directly on 32-bit microcontrollers such as STM32, ESP32-S3 and ESP32-P4 – without Linux, Windows or conventional PLC infrastructure. In the CL system, sensors and actuators are connected, and control loops and sequences, motion control (Stepper Move, Stepper Position, Stepper Path/G-Code) and user interfaces for display and smartphone are created graphically using function blocks; simulation, live diagnostics, firmware management and process data collection (PDC, e.g. InfluxDB, Modbus TCP) are integrated. The system has been in productive use for more than 10 years and is part of over 50 real-world applications at more than 20 industrial companies, including machine and plant control systems, embedded devices, distributed systems, retrofit projects, prototyping and education. In addition to compatible boards from various manufacturers, proprietary controllers are offered, from a compact entry-level board to an industrially designed edge controller (24 VDC, CAN bus, galvanically isolated I/Os).
