The next few pages show three specific examples: Example #1: Master is issuing Modbus command with FC 16 (with Float Flag: Yes) to transfer Float data to slave. (Float specific module parameters) Float Flag: "Y" tells the master to consider the data values that need to be sent to the slave as floating point data where each data value is composed of 2 words (4 bytes or 32 bits). Float Start - Tells the master that if this address number is <= the address number in Addr in Dev parameter to double the byte count quantity to be included in the Command FC6 or FC16 to be issued to the slave. Otherwise the master ignores the Float Flag: Y and treat data as composed of 1 word, 2 bytes. (Modbus Command parameters) DB Addr - Tells the master where in its data memory is the beginning of data to obtain and write out to the slave device. Reg Count - Tells the master how many data points to send to the slave. Two counts mean two floating points with Float Flag: Y and the Addr in Dev greater than or equal to the Float Start Parameter. Swap Code - Tells the master how to orient the Byte and Word structure of the data value. This is device dependent. Check Command Entry formats Section. Func Code - Tells the master to write the float values to the slave. FC16. Addr in Dev - Tells the master where in the slave's database to locate the data

In the above example, the master's Modbus command to transmit inside the Modbus packet is as follows. Slave Address Function Code Address in Device Reg Count Byte Count Data DEC 01 16 7100 2 8 85.37 22.86 HEX 01 10 1B BC 00 02 08 BD 71 42 AA E1 48 41 B6 In this example, the master's Modbus packet contains the data byte and data word counts that have been doubled from the amount specified by Reg Count due to the Float flag set to Y. Some slaves look for the byte count in the data packet to know the length of the data to read from the wire. Other slaves know at which byte the data begins and read from the wire the remaining bytes in the packet as the data the master is sending
