GCAN-IO-8100 Modbus I/O Coupler can be used to connect Modbus system and distributed bus terminal module, and these terminal modules can be expanded in a modular way. A complete node consists of a bus coupler, 1-32 arbitrary number of terminal modules and a terminal module
GCAN-IO-8100 ModbusBus Coupler uses standard Modbus protocol, a standard slave station. The GCAN-IO-8100 Bus Coupler has two kinds of style, GCAN-IO-8100-TCP supports Modbus TCP communication, GCAN-IO-8100-RTU supports Modbus RTU communication. Besides, the firmware can be upgraded by configuring the interface. GCAN-IO-8100 Bus Coupler supports automatic configuration, and you do not need to set parameters on the PC. When GCAN-IO-8100 bus coupler uses Modbus RTU communication, communication parameters can be configured by RS485 interface; When uses Modbus TCP communication, communication parameters can be configured by Ethernet interface.
