EtherNet/IP Communication (Adapter)
Overview
The KW2D Series Smart RFID Reader works as an adapter in EtherNet/IP communication and communication can be
performed with devieces such as programmable display, PLC, that are compatible with EtherNet/IP communication.
EtherNet/IP communication also uses standard Ethernet technologies, which allows networks to be built that include
various Ethernet-compatible devices.
Multi-vendor networks between EtherNet/IP devices
You can build a multi-vendor network with EtherNet/IP equipment.

EtherNet/IP Equipment(Adapter)

When EtherNet/IP communication and other Ethernet communications are performed simultaneously on thesame network, data may no longer be transmitted or received at the intended timing, depending on the load
status. In this situation, build the network using an Ethernet switch that supports the QoS function andadjust the priority of data that flows on the network.

2.2

EtherNet/IP Adapters
The KW2D Series Smart RFID Reader provides the following functions as an adapter for EtherNet/IP devices• I/O message communication (target) function (Class 1 communication)• Class3/UCMM communication● I/O Message Communication Overview■ What is I/O Message Communication?
I/O message communication is a function that allows EtherNet/IP devices to cyclically read and write data with eachother. The target unit for reading/writing data is called a CIP connection point. CIP tag names and instance IDs are
assigned to CIP connection points. In I/O message communication, an EtherNet/IP device reads/writes data by
specifying the CIP tag name or instance ID of a CIP connection point.
■ What is a CIP connection?
A CIP connection is a virtual communication line between EtherNet/IP devices. In I/O message communication, one
device sends a request to open a CIP connection to the CIP connection point of the other device, and when successful,data is read and written.The side that sends the request to open the CIP connection is called the originator. The sidethat receives the request is called the target. The KW2D Series Smart reader can be the target. The KW2D Series
Smart reader can open 3 CIP connections at the same time.
● Types of CIP Connections
There are the following three types of CIP connections. Exclusive Owner can transmit and receive data. Input Only and
Listen Only can only receive data.

KW2D Series Smart RFID Reader User’s Manual

4Communication Function■ Exclusive Owner
This CIP connection cyclically transmits data from the target to the originator (1) and cyclically transmits data from theoriginator to the target (2). The CIP connection point is specified as a CIP tag name or an instance ID. Communicationis performed at the cycle (RPI) specified when the CIP connection is opened*1. Data can be transmitted and received
when the originator opens*2 the connection.

2 EtherNet/IP Communication (Adapter)■

Input Only
This CIP connection cyclically transmits data from the target to the originator (1). The CIP connection point is specified
as an instance ID. Communication is performed at the cycle (RPI) specified when the CIP connection is opened. Inorder for the target to perform alive monitoring of the originator, a heartbeat that does not include data is cyclicallytransmitted from the originator to the target. The originator specifies the Input Only instance ID (198) on the target as
the destination for the heartbeat. The heartbeat is transmitted at the specified cycle (RPI).

2 EtherNet/IP Communication (Adapter)■ Listen Only
This CIP connection cyclically receives data for originators from a target that already has a multicast type CIP
connection using Exclusive Owner or Input Only opened. Set this connection type to simultaneously receive data when
the target transmits that data by multicast to other originators. The CIP connection point is specified as an instance
ID. Communication is performed at the cycle (RPI) specified when the CIP connection is opened. In order for thetarget to perform alive monitoring of the originator, a heartbeat that does not include data is cyclically transmitted
from the originator to the target.
The originator specifies the Listen Only instance ID (199) on the target as the destination for the heartbeat. The
heartbeat is transmitted at the specified cycle (RPI).

■ Change Of State
Send data when there is a change from originator to target or from target to originator. If there is no change in data,
it will send data at every regular cycle in the RPI.
● Types of connections
There are two types of KW2D Series Smart RFID Readers with the following connection types■ Point To Point
Send data from the originator to the target or from the target to the originator by one-to-one.
■ Multicast
Sends data from the target to the multicast addresses of multiple originators. The direction of the target from theoriginator is not supported.

An undefined value is stored in the address number with "Reserved" in the Contents.

*1 After reading the RFID tag, the tag information is retained for up to three seconds. After that, it is set to the initial value.
*2 The input register 0031 (number of detections) counts up for each tag detection. Since the tag information value is updated at the sametime as the count is increased, the memory update timing can be grasped by monitoring the change in the number of detections.

Event Transmission (TCP, UDP)
Overview
The KW2D Smart RFID Reader supports event transmission (TCP) and event transmission (UDP). Hereafter, if there isno difference between event transmission (TCP) and event transmission (UDP), it is simply called the event
transmission.
When an RFID tag is detected, the event transmission sends the detected RFID tag data to the host device in thespecified format.
For the event transmission (TCP), the KW2D smart RFID reader acts as a client and performs TCP communication withthe host device of the server. The connection with the TCP server is established when the event transmission is
executed, but whether to release or maintain the connection can be selected in the option settings.
The event transmission (UDP) performs the UDP communication with the host device without a connection.

The tag information of the read RFID tag is written to
the shared memory. After the writing is completed,the host device waits for a response as a result of
reading and collating the tag information of theshared memory. The response wait time is up to 3
seconds.

A transition may be made to the "Detection mode (holding detection result)" immediately depending on thecommunication status.
When the Turn off during running is enabled, the LED (white) turns off during operation. For details, refer to

KW2D Series Smart RFID Reader User’s Manual

1 KW2D Series Smart RFID Reader Statuses and Operations● Unlock operation
When the lock is canceled, the KW2D Series Smart RFID Reader sets the tag information to the initial value andtransitions to "operation mode (running)".
The unlocking method varies based on the contents set in Lock Mode under the Tag Read Settings on the RFID
Reader Settings tab of KW RFID Configurator.
Enable (Holding): Detach RFID tag
Enable (Time):• Wait for the specified time to elapse• Hold up the same RFID tag again• Manipulate the value of the coil relay (page 5-11)

When you hold up the RFID tag again to forcibly release the lock operation, hold up the RFID tag at least 2
seconds apart. If the interval is short, releasing the lock operation may fail.
• The lock time starts counting down when the RFID tag is removed from the KW2D Series Smart RFID
Reader after the it was held up to the RFID reader and locked.
• When "Disable" is selected in Lock Mode, the KW2D Smart RFID Reader does not shift to "lock mode
(during lock operation)". The mode shifts from "detection mode" to "operation mode (running)".
● Pausing the lock operation
You can pause the timer that counts the lock time to continue the "lock mode (during lock operation)" status. To pause
the timekeeping, manipulate the value of the coil relay. For details, refer to "2.2 Operate the KW2D Smart RFID
Reader" on page 5-18.

Adjusting the RFID Tag Detection Sensitivity
This section describes how to adjust the RFID tag detection sensitivity.
Set the reading distance and reading time for RFID tags with Reading Distance and Reading Time under the Tag
Read Settings on the RFID Reader Settings tab in the KW RFID Configurator.

• For Reading Distance, specify the distance from the RFID tag to the KW2D Series Smart RFID Reader as a value
between 7 (near) and 0 (far). This distance is shown as the RSSI (received signal strength) value in eight steps.
• For Reading Time, specify the response time from when the RFID tag is held up to the KW2D Series Smart RFID
Reader as a value between 300 milliseconds (quick) and 3000 milliseconds (slow). The value can be set in ten steps
in increments of 300 milliseconds.
The response time has a margin of error of -300 milliseconds. This means the response time is detected between
300 to 600 milliseconds when 600 milliseconds is specified.
Increase the response time to prevent detection of RFID tags when they mistakenly touch the KW2D Series Smart
RFID Reader. For details, refer to Chapter 6 "Tag Read Settings" on page 6-12
• When using a KW2D Series Smart RFID Reader with a tag holder, the tag may be detected before the tag isplaced in the holder. Set the reading distance to RSSI value: 6 or 7 (near) to prevent detection of the tag
before it is placed in the holder.
• The KW2D Smart RFID Reader is in "detection mode (detecting RFID tag)" from the time the tag is held up
until the tag detection is confirmed. For details, refer to "Detecting an RFID tag" on page 5-3.

Edit the tag list
The tag list registered in the KW2D Smart RFID Reader can be edited by using the master tag or by operating theshared memory from the host device.
When the Protect check box in the tag list is cleared, you can edit the tag list even if the project is password
protected.
The processing of the KW2D Smart RFID Reader and tag list varies based on the operation performed in "tagedit mode (registering)" or "tag editing mode (deletion)".
• Download project or tag list
Discards the tag list being edited and shifts to "operation mode (running)". After downloading, it works withthe downloaded tag list.
• Upload project
Keeps the tag list being edited in "tag edit mode". However, the uploaded tag list is the one before editing.

● Use master tags
You can enable or disable the RFID tags registered in the tag list, and register the read RFID tags in the tag list withthe registration master tag or deletion master tag prepared in advance. For the master tags, refer to Chapter 6 "MasterTag" on page 6-14.
Enable or register RFID tags
Enables RFID tags that are registered in the tag list and whose Enable/Disable is "Disabled".
For RFID tags that are not registered in the tag list, registers the UID of the read tag.

Disable:It does not enter "lock mode (locking)". If you keep holding an RFID tag, the"operation mode" and "detection mode" will be repeated.

Enable (Holding): When you hold an RFID tag for 1.5 seconds or longer, it will be in "Lock mode
(locking)", and when you release the RFID tag, the locking operation will be
released.
Enable (Time):

Hold an RFID tag to enter "lock mode (locking)". The lock operation is released
when the specified time (1 to 28,800 seconds) elapses from the time when the
RFID tag is released. If you hold the same tag again before the specified time
elapses, the lock operation will be released at that point.

Reading Distance: Specify the distance at which the KW2D Series Smart RFID Reader can read RFID tags in 8 steps
by sliding the slider or clicking / .
The RSSI value (0 to 7) of each specified step is displayed to the right of the slider.
The RSSI value indicates the received signal strength, which is the signal strength when the KW2D
Series Smart RFID Reader reads the RFID tag. An RSSI value of 7 (near) means the strongest
signal strength and a value of 0 (far) means the weakest signal strength. The signal strength
becomes smaller the further the distance between the KW2D Series Smart RFID Reader and RFID
tag. For this reason, the KW2D Series Smart RFID Reader controls the distance between the RFID
reader and RFID tag by judging the detection of the RFID tag only when the RSSI value is greaterthan or equal to the set RSSI value.
For example, when the RSSI value is 7 (received signal strength: maximum), reading signal
strengths lower than 7 is abandoned.
Reading Time :Specify the response time to read the RFID tag in 10 steps by sliding the slider or clicking / .
The time (300 to 3000 ms in increments of 300 ms) of each specified step is displayed to the rightof the slider.
