2. The TeleBUS RTU and ASCII protocols support two type of Modbus station addressing Standard Modbus addressing allows a maximum of 255 stations and is compatible with standard Modbus devices Extended Modbus addressing allows a maximum of 65534 stations Extended Modbus addressing is fully compatible with standard Modbus addressing for addresses between 0 and 254 Theory of Operation The address field of a Modbus message is a single byte Address 0 is a broadcast address messages sent to this address are sent to all stations Addresses 1 to 255 are station addresses Figure 1 shows the format of a standard Modbus message Field Address Function 1 N Size 1 Figure 1 Standard Modbus Message The address field extension adds a two byte extended address field to the message Figure 2 shows the format of an extended address Modbus message Field Addres Extended Extended Function s 255 Address Address high low Size 1 1 1 1 n Figure 2 Extended Address Modbus Message Messages for addresses 0 to 254 use the standard format message The station address is stored in the address byte Messages for stations 255 to 65534 use the extended address format message The address byte is set to 255 This indicates the extended address format is used The actual address is stored in the two extended address bytes Station address 65535 is reserved and cannot be used as a station number This station address is used in store
