softMOD is the industry-standard Modbus protocol stack for industrial automation and building automation. softMOD supports both Modbus RTU (Remote Terminal Unit) and Modbus TCP/IP (Transmission Control Protocol) in client and server modes. SoftMOD runs on a very broad range of hardware and operating systems.
softMOD RTU supports simple RS-232 and RS-485 serial interfaces, hence it does not require complicated wiring or installation procedures.
SoftMOD TCP/IP requires an Ethernet interface and can run over an existing Ethernet network. TCP/IP client stack is available with a REST interface and also runs in a Linux docker container.
