Raspberry Pi CM4-powered CODESYS industrial controller supports EtherCAT, Modbus, up to 32 I/O modules

EDATEC ED-PLC2010 is an industrial controller powered by a Raspberry Pi CM4, supporting EtherCAT and Modbus interfaces, up to 32 I/O modules, and preloaded with CODESYS runtime for real-time core and visualization capabilities.

DIN Rain-mountable Raspberry Pi CM4 industrial controllers are not exactly new, with products such as Modberry 500 CM4 and Edgebox-RPI4 announced shortly after the launch of the Raspberry Pi Compute Module 4 in 2020. More recently (2024), Seeed Studio introduced the reComputer R1113-10 IoT gateway, and Sfera Labs launched the Strato Pi Max. TECHBASE also upgraded the Modberry 500 with a more powerful CM5 module. EDATEC ED-PL2010 mostly differentiates itself by shipping with a licensed version of CODESYS runtime for industrial automation. It’s also possible with other vendors, but the license might need to be purchased separatly.
