If the bit shifted out to the right is zero return to step 3. If the bit shifted out to the right is one, exclusive OR the generating polynomial 1010 0000 0000 0001 with the 16-bit register. Shift the 16-bit register one bit to the right. Exclusive OR the first 8-bit byte with the high order byte of the 16-bit register, putting the result in the 16-bit register. The step by step procedure to form the CRC-16 is as follows: Load a 16-bit register with all 1’s. Error Detection There are two types of errors which may occur in a communications system: transmission errors and programming errors. In the ASCII mode, breaks of up to one second can occur between characters to allow for a relatively slower master. Additionally, in the RTU mode, message characters must be transmitted in a continuous stream. The ASCII mode uses twice as many characters as the RTU mode, but decoding handling the ASCII data is easier. The protocol provides for one master device and up to 247 slave devices on a common line.

MODBUS is a Master/Slave communications protocol, whereby one device, (the Master), controls all serial activity by selectively polling one or more slave devices. Modbus Message Formatting The MODBUS protocol describes an industrial communications and distributed control system developed by Gould-Modicon to integrate PLC’s, computers, terminals, and other monitoring, sensing, and control devices.
