Network Protocols The Ethernet card uses TCP/IP protocols for network communications. The supported protocols are: ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, and SNMP. Per the Modbus/TCP specification, the Modbus data messages are transported by TCP for error-free data transport end-to-end. Firmware updates can be done with the TFTP protocol. The IP protocol defines addressing, routing, and data block handling over the network. IP Address and Modbus Slave Address Every device connected to the TCP/IP network including the Ethernet card must have a unique IP address. When multiple Modbus devices share a single IP, then Modbus/TCP includes an additional address called the Unit ID. See IP Addresses, Netmask (page 27) for a complete description of IP Addressing. When the Ethernet card is receiving Modbus/TCP messages from remote masters, the Unit ID is converted to use in the Modbus/RTU message as the slave address.
