Carlo Gavazzi EM100, ET100, EM111, EM112 MODBUS registers: read online

Connect Carlo Gavazzi to the computer through a USB-to-serial or RS485 adapter and read its registers in your browser: click "Read register values online" under the model (Chrome or Edge, nothing to install). The tables below list the MODBUS offset, unit, data type and scale of every register shown. For logging 24/7 into a database, CSV files or Excel, use the Advanced Serial Data Logger (for MODBUS RTU) or Advanced TCP/IP Data Logger (for MODBUS TCP): they poll the complete map of every model on this page and provide continuous Carlo Gavazzi data logger and record.
