Modbus Gateway

Come-Star offers a comprehensive range of industrial Modbus gateways, engineered to ensure seamless communication between Modbus devices and modern network systems. Our gateways provide reliable and secure data transfer across various industrial protocols, enabling effective integration of legacy systems with newer network infrastructures. Available in 2, 4, and 8-port configurations, these gateways support both Modbus Ethernet to serial and Modbus TCP to serial communication, facilitating smooth and efficient data exchange.The Modbus TCP/IP to Ethernet/IP gateway ensures compatibility between Modbus-based devices and Ethernet/IP networks, providing flexibility in industrial automation systems. Whether you need to bridge Modbus RTU over Ethernet or integrate Modbus TCP/IP with existing industrial Ethernet protocols, our Modbus gateways offer a robust solution for any application requiring reliable, real-time data transmission across networks. Built for harsh environments, our industrial Modbus gateways deliver high performance and reliability in mission-critical industrial automation, control, and monitoring applications.

Cgate3204 Series

4*RS232/RS485 to 2*Ethernet Ports Modbus Industrial Gateway

  • Support 4 x RS232/RS485 serial port to 2 x 10/100Base-T(X) auto-sensing Ethernet ports
  • Support conversion between ModlbusRTU/ASCII and Modlbus TCP protocols, and support Modlbus RTU/ASCII Over TCP transparent transmission
  • Support Modlbusslave readahead, single port automatically learns up to 256 RTU or 128 ASCII instructions, and pre-reads data to achieve fast response
  • Support Modlbus address mapping, mapping a single read/write instruction with read/write instructions of multiple addresses, realizing batch read/write with a single instruction
  • Support serial port forwarding, realizes transparent transmission of data between the serial port and other serial ports, and provides one-way forwarding/receiving and two-way forwarding direction control
  • Support JSON function, which can convert the collected Modlbusslave device data into JSON format and send it to the server
  • Support dual DC 9~60V redundant power input, support non polarity
  • High-strength aluminum alloy casing, IP40 protection level, fan-less casing for heat dissipation, the equipment can reliably work in harsh industrial environments of -40℃~+85℃
