1 Overview
EZI-10 is a remote digital I/O Controller. This device lets us not only control remote
devices’output but also monitor remote devices’input. There are two ways for the
communication on TCP/IP.
The one is HTTP. This way is quite simple because you can use it just running a web
browser. You don’t need to make an application.
The other one is Modbus/TCP. This way allows users to set some detailed and
complicated operations. To use Modbus/TCP, you should make an application or use the
ModMap which is a Modbus/TCP application offered by us for free.
This document describes an example of “Internet Switch”application.

Figure 1-2 an application of Internet Switch (switch OFF)
You are allowed to control remote digital output by using two of EZI-10 as you can see
in the above systems.

2 Configuration
2.1 Master
Modbus/TCP consists of a master and slaves. A master sends queries to the slaves and
slaves reply the queries. You have to designate which one will be a master or which one
will be a slave considering your network environment.
2.1.1 Setting Network Parameters
ezConfigIO is the tool for configuring parameters of EZI-10.
Connect EZI-10 to your network and run ezConfgIO on your PC. Referring to the below
figure, set network parameters.

2.1.2 Setting TCP/IP Parameters
To communicate on Modbus/TCP, a master and a slave should be connected on TCP. The
one which tries to make connection sending [SYN] segments is called TCP client and the
one which waiting connection request segments from clients is called TCP server. Usually, a
master is set to a TCP client. (Modbus / Active)

②Click the [Write] button.
 It is okay to set the master to TCP server (Modbus / Passive) if you need it.

2.2 Slave
2.2.1 Setting Network Parameters
The way of setting network parameters of slaves is the same with the master’s.

2.2.1 Setting TCP/IP Parameters
Usually, a slave is set to a TCP server. (Modbus / Passive)
 In case that the master is set to a TCP server, the slave should be a TCP client.

3 Operation
3.1 Basic Operation
There are two basic operations in this application.
Automatic Control of the Master’s OUTPUT by the Slave’s INPUT
Figure 3-1 basic operation 1
Automatic Control of the Slave’s “OUTPUT by the Master’s INPUT
Figure 3-2 basic operation 2

3.2 Advanced Operation
You can use this application in detail by using the below parameters.
Figure 3-3 advanced operation
Valid Time
EZI-10 recognizes that the input signal is valid only if the signal keeps HIGH for the
value of [Valid Time]. That means all shorter signals than the value of [Valid Time] are
ignored. The unit is 10ms.
Notify Input Port Change
This option lets EZI-10 send response segments to the counterpart immediately when
its input port state has been changed without queries.
Delay
EZI-10 delays output as much as time set to the value of [Delay]. The output signal
should be maintained by the point of operation time and any other outputs can be
acceptable when timer is running by this option. The unit is 10ms.
