ES Series Gateway is an Ethernet device and a Modbus serial devices interconnected gateways. Connect the Modbus TCP protocol to the Modbus RTU/ASCII(RS485/RS232)device.

1. Ethernet 10/100M, built-in network isolation transformer;
2. Two Ethernet RJ45 interface, built-in switch function, support cascade, can be used in a ring network, and can save cables and switches in field connections;
3. Support mapping slave ID;
4. Support automatically routing the requests to the serial interface;
5. Support network security settings: limit the communication client IP address range and set login password;
6. As Modbus TCP server, support up to four connections, and can simultaneously support 32 commands request;
7. As Modbus TCP client, support accessing four different IPs or different ports of Modbus TCP server;
