2. Terms and Definitions
Below is a list of terms used in this manual and their definitions.
Term
Description/Definition
IP Address Ethernet uses IP addresses to achieve communications.
Each IP address (specifically, Internet Protocol address) identifies a
specific node (host computer, controller, etc.) on an Ethernet network,
IP addresses must be set and managed so that they are not duplicated.
Socket A socket is an interface that allows you to directly use TCP or UDP
functions from the user program.
CJ Series Programmable Controllers support socket services in the
following ways.
• Manipulating dedicated control bits in the CPU Bus Unit Area in the
CIO Area
• Sending FINS commands (CMND instructions) to the Ethernet Unit
To use socket services, you need to establish a connection with a remote
node and disconnect it after use. In this document, processing for
establishing a connection is referred to as “socket open” or “TCP open”
and for disconnecting it as “socket close” or “close”. You can use the
socket services to send and receive arbitrary data to and from the remote
node.
Active and Passive When you open a TCP socket connection with nodes, open processing is
executed for each node.
The method to open a connection differs depending on whether the node
is to serve as a client or server.
In this document, processing to open a connection as a server is referred
to as “passive open” and as a client is referred to as “active open” or
“active open processing”
keep-alive Function When a remote node (server or client) does not respond for a set period
of time or longer in TCP/IP socket services, the keep-alive function sends
a communications frame to the node to check the connection status.
If the node does not respond to it, the function performs this check at a
certain interval, and closes the connection if it does not respond to all
check frames.
linger function This is a TCP socket option that sends RST data when the TCP socket is
closed. This enables immediate open processing using the same port
number, without waiting for the port to be opened.
If the linger option is not specified, the controller issues FIN data when
the TCP socket is closed and, after that, performs end control such as a
send data arrival check with the remote node for approximately 1 minute.
Therefore, TCP sockets with the same port number may not be used
immediately.

4. Overview
This document describes the procedures for connecting the OMRON Industrial Handheld
DPM Reader products (V460-H Series) to a CJ Series Programmable Controller (hereinafter
referred to as the controller) via Ethernet and for checking their connections.
You can establish an Ethernet communication connection by understanding the setting
procedures and key points of setup through the Ethernet communications settings in the
“CX-Programmer Project File” prepared in advance.
In this project file, the Ethernet connection is checked by sending a read trigger command to
the code reader and receiving the read data from it.
Obtain the latest version of the CX-Programmer Project File from OMRON in advance.

The purpose of this document is to describe the wiring methods, communication
settings, and setting procedures required to establish a connection for
communications with applicable devices. In addition, the program used in this
document is designed to check that the connection has been correctly
performed (connection check). Since t
he program is not intended for permanent
use on-site, full consideration is not given to functionality and performance.
When configuring an actual system, please refer to the wiring methods,
