1 Modbus Overview

1.1 Modbus

Modbus is a serial communications protocol originally published by Modicon (now

Schneider Electric) in 1979 for use with its programmable logic controller (PLCs).

As a matter of fact, Modbus has become a standard communication protocol.

Modbus serial line protocol is a master-slave protocol that a master communicates

with one or more slaves. A master sends Modbus queries to slaves and slaves send

responses to the master.

There are two transmission modes in Modbus serial line protocol and those are RTU

and ASCII. Comparisons of those two modes are as follows:

Division

Modbus/RTU

Modbus/ASCII

Basic

Commonly used

More efficient than ASCII mode

Less efficient than RTU mode

Used when the timer-related

requirements of the RTU mode

cannot be met

Table 1-1 Comparisons of Modbus/RTU and Modbus/ASCII

With the evolution of networks, the demand for network communications of

industrial equipment has also increased. As a result, a network version became a

necessity for the Modbus protocol, the TCP/IP version called Modbus/TCP is released.

1.2 Modbus Gateway

Figure 1-1 Modbus Gateway

Devices that use Modbus/TCP cannot directly communicate with devices that use

serial line Modbus protocols. Because not only the physical interfaces are different

but also the protocols are not compatible. To facilitate communication between the

two devices, an additional device is required to route the Modbus data from each

device. The device that performs this role is known as a Modbus Gateway.
