Compact Controller 100 from Wago combines PLC functionality with integrated digital and analog I/O in a 108-mm-wide, DIN-rail-mounted design. Programmable with Codesys V3, it supports IEC 61131-3 languages on a real-time Linux operating system. Two Ethernet interfaces can operate on a common network or separate networks, while an RS-485 interface supports Modbus RTU communications. Web-based management provides browser access to configuration and controller status. Pluggable picoMax connectors enable prewiring to speed installation and avoid rewiring during device replacement.
