1 Introduction
1.1 Overview
Advantech’s ADAM-4572 and EKI-1221/1222/1224/1221D/1222D series of Modbus
Gateways (the following manual will use EKI-122X series instead of complete model
name) are a robust, feature-rich, and cost effective way to integrate of Ethernet and
Serial Modbus devices. The ADAM-4572 and EKI-122X series provides one, two or
four serial ports, one or two Ethernet ports, a wide range of power inputs, and a
compact slim design, making them an ideal solution for connecting multiple Modbus/
RTU and Modbus/ASCII serial devices to Modbus TCP (Ethernet).
Originally developed for PLCs in industrial automation and manufacturing control
applications, Modbus is one of the most popular open standard protocols in use
today. The communication mode can be Modbus R TU/ASCII (Serial) or Mo dbus TCP
(Ethernet). Many industrial devices use Modbus as their communication standard.
However, the Ethernet-based Modbus protocol is different from the original serialbased protocols that a Modbus Gateway is needed to be a bridge for integration.
The two Ethernet ports allow the EKI-122X series to establish two separated
Ethernet connections to two Ethernet domains or two Ethernet switches in the same
domain. Through a dual Ethernet connection, the EKI-122X series greatly improves
the device connectivity reliability, increase system stability, and simplify the
redundant configuration.
The Modbus/RTU and Modbus/ASCII protocols define how a “master” device polls
one or more “slave” devices and write real-time data over RS-232, RS-422, or RS485 serial data communication. The ADAM-4572 and EKI-122X series provides a
feature that can allow users to select master or slave operation for each serial port.
The ADAM-4572 and EKI-122X series not only allows Ethernet master can control
serial slaves, but also allow serial masters to control Ethernet or serial slaves.
Furthermore, the EKI-122X series can allow both Ethernet and serial slaves to be
controlled by both Ethernet and serial masters.
The ADAM-4572 and EKI-122X series supports various operating modes: RTU
Master, RTU Slave, ASCII Master, and ASCII Slave.
1.2 Features
Provides dual 10/100 Mbps auto-sensing Ethernet ports (EKI-122X series only)
Integration of Modbus TCP and Modbus RTU/ASCII networks
Supports COM port's baud rate up to 921.6 kbps
Supports up to 16 TCP connections and 32 requests simultaneously
Supports 31 slaves (RS-485) per serial port
Supports auto-bypass function (EKI-1221D/1222D only)
Software selectable RS-232/422/485 communication
Auto searching slave ID over configuration utility
Mounts on DIN-rail, wall, or panel

2 Getting Started
2.1 Understanding Modbus Gateways
Networks have become increasingly vital for industrial automation applications. Many
control devices today do not have a network port and can only communicate with a
dedicated local PC or control panel. Advantech’s revolutionary network-enabling
technology is now allowing control devices with serial ports to connect to the Ethernet
and share networks quickly and cost-effectively. The ADAM-4572 and EKI-122X
series are network-based, Modbus gateways for integrating new and existing
Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based
devices. Manufacturers, system integrators, and end users can now take advantage
of Modbus gateways to create networked applications for remote managing and
accessing data for their control devices that wasn’t possible before.
2.1.1 Protocol Overview
Originally developed for PLCs in industrial automation and manufacturing control
application, Modbus has become one of the most popular open standard protocols in
use today. When it comes to planning data communication for open, multi-vendor
industrial control systems, Modbus is the first choice of end-users and integrators.
Although it’s not the most powerful protocol available, its rare simplicity allows not
only rapid implementation, but also remains flexible enough to be applied in virtually
all industrial situations. The communication mode of Modbus can be ASCII, RTU, or
TCP/IP. Modbus gateways are used to support applications such as protocol conversion between serial (Modbus/ASCII or Modbus/RTU) and networked (Modbus/TCP)
Modbus devices or it can be used to bridge Modbus serial devices over TCP/IP network.
The Modbus/RTU and Modbus/ASCII protocols define how a “master” device polls
one or more “slave” devices to read and write real-time data over RS-232, RS-422, or
RS-485 serial data communication. The simplicity of Modbus/RTU not only allows
rapid implementation, but can also remain flexible enough to be applied in virtually all
industrial situations.
During Modbus network communication, the protocol determines how each controller
will know its device address, recognize a message addressed to it, determine the
kind of action to be taken, and extract any data or other information contained in the
message. If a reply is required, the controller will construct the reply message and
send it back using Modbus protocol.
The way controllers communicate with each other is by using a master-slave technique, in which only one device (the master) can initiate queries. The other devices
(the slaves) respond by supplying the requested data to the master, or by taking the
action requested in the query. Typical master devices include host processors and
programming panels. Typical slaves include programmable controllers.
It is the master that can address individual slaves and initiate a broadcast message
to all slaves. On the other hand, slaves return a response to queries that are
addressed to them individually. Responses are not returned to broadcast queries
from the master.
The Modbus protocol has a definite format for the master’s query , which incorporates
the device (or broadcast) address, a function code defining the requested action, any
ADAM-4572 & EKI-122X Series User Manual 6
data to be sent, and an error-checking field. The slave’s response message, which is
also constructed using Modbus protocol, contains fields confirming the action taken,
any data to be returned, and an error-checking field. If an error occurred in receipt of
the message, or if the slave is unable to perform the requested action, the slave will
construct an error message and send it as its response.
The basic system architecture is as below:

Figure 2.2 Modbus System Architecture 2
7 ADAM-4572 & EKI-122X Series User Manual
2.1.2 Modbus RTU
The Modbus/RTU protocol defines how a “master” device polls one or more “slave”
devices to read and write data in real-time over RS-232, RS-422, or RS-485 serial
data communication.
When using RTU mode, each 8-bit byte in a message contains two 4-bit hexadecimal
characters. The main advantage of this mode is that its greater character density
allows better data throughput than ASCII mode for the same baud rate. Nevertheless, each message must be transmitted in continuous stream.
2.1.3 Modbus ASCII
When using ASCII mode, each 8-bit byte in a message is sent as two ACSII characters. The primary advantage of this ASCII mode is that it allows time intervals of up to
one second to occur between characters without causing an error.

2.1.4 Modbus TCP
As a new extension of Modbus/RTU, the Modbus/TCP protocol defines how Modbus/
RTU messages are encoded within and transported over TCP/IP-based networks.
Modbus/TCP is just as simple to implement and flexible to apply as the original Modbus/RTU. The Modbus/TCP protocol is defined by its form of encapsulation for a
Modbus request or response. That means the Modbus request or response data is
encapsulated in TCP frame that has a six-byte header in Modbus/TCP protocol.
Modbus/TCP enables the use of Modbus messaging in an Intranet running the TCP/
IP protocols. Modbus/TCP is most commonly used for Ethernet attachment of PLC’s
or I/O modules to other simple field buses or I/O networks.
