SAFETY PRECAUTIONS 
(Read these precautions before using this product.)
Before using this product, please read this manual, the relevant manuals, and the safety standards carefully
and pay full attention to safety to handle the product correctly.
The precautions given in this manual are concerned with installation of this product and wiring with the
external application only.
For the safety precautions of the MELSEC-WS safety controller system, refer to the user's manual for the
CPU module used.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
[Design Precautions]
WARNING
The Ethernet interface module is not suitable for operation on a safety fieldbus.
The Ethernet interface module only generates non-safety-related fieldbus data (status bytes) for control
and diagnostics purposes.
Do not use non-safe data from an Ethernet interface module for safety related applications.
With the Ethernet interface module it is possible to integrate non-safe data into the logic editor such that
the safety function of the MELSEC-WS safety controller is compromised. Never implement the Ethernet
interface module into a MELSEC-WS safety controller without having this danger checked by a safety
specialist.

2
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100 mm or more between them.
Failure to do so may result in malfunction due to noise.
The MELSEC-WS safety controller fulfils the requirements of Class A (industrial applications) in
accordance with the "Interference emission" basic specifications.
The MELSEC-WS safety controller is therefore only suitable for use in an industrial environment and not
for private use.
[Installation Precautions]
CAUTION
Use the MELSEC-WS safety controller in an environment that meets the general specifications in the
user’s manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or
damage to or deterioration of the product.
Latch the module onto the DIN rail. Incorrect mounting may cause malfunction, failure or drop of the
module.
To ensure full electromagnetic compatibility (EMC), the DIN mounting rail has to be connected to
functional earth (FE).
Ensure that the earthling contact is positioned correctly. The earthling spring contact of the module must
contact the DIN rail securely to allow electrical conductivity.
Additionally connect all network cable shields directly at the control cabinet entrance to a common FE
ground line.
Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Shut off the external power supply (all phases) used in the system before mounting or removing the
module.
Failure to do so may result in damage to the product.
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
The MELSEC-WS safety controller is only suitable for mounting in a control cabinet with at least IP 54
degree of protection.
Failure to meet the installation method may cause the module to fail or malfunction due to the deposition
of dust or the adhesion of water.
Make sure that the connection of the Ethernet interface module cannot lead to hazardous
situations during installation.
Ensure that the connection of the Ethernet dedicated cables and power cables cannot lead to a
hazardous situation when implementing the unit on to the MELSEC-WS safety controller and Ethernet
network. Prevent unintended start-up of equipment during connection of a Ethernet interface module.
Failure to do so may cause the system to malfunction.

CAUTION
Switch the entire machine/system off line.
The system could start up unexpectedly while you are connecting the devices.
Connectors for external devices must be crimped or pressed with the tool specified by the manufacturer,
or must be correctly soldered. Incomplete connections could result in short circuit, fire, or malfunction.
Connect the connectors to the module securely.
Failure to do so may cause malfunction due to poor contact.
Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables
or malfunction due to poor contact.
Tighten the terminal screw within the specified torque range.
Undertightening can cause short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
When disconnecting the cable from the module, do not pull the cable by the cable part.
When disconnecting the cable with connector from the module, hold the connector part.
When disconnecting the cable connected to a terminal block, loosen the terminal screws first.
Failure to do so may result in damage to the module or cable or malfunction.

This chapter describes the Ethernet interface module (WS0-GETH).
3.1 Overview
The Ethernet interface module is connected to Setting and Monitoring Tool, a
MELSEC programmable controller, and PC via TCP/IP. The module can:
Exchange configuration data and programs of a MELSEC-WS safety controller
by connecting to Setting and Monitoring Tool via TCP/IP.
Exchange non-safety related data by connecting to an external application (e.g.
MELSEC programmable controller, PC) via TCP/IP.
3.1.1 Interfaces and operation
The Ethernet interface module is equipped with an integrated three-port switch for
connection with the Ethernet network. Two RJ45 sockets are available for the
connection. The switch functionality allows the Ethernet interface module to be used
for connection to another Ethernet component (e.g. connection to a notebook)
without having to interrupt the Ethernet connection to the network. (One IP address
can be configured.)

3.2 Mounting/Dismantling
This chapter describes the mounting of the Ethernet interface module.
Make sure that the connection of the Ethernet interface module cannot
lead to hazardous situations during installation!
Ensure that connecting an Ethernet interface module cannot lead to a hazardous
situation when implementing the unit on to the MELSEC-WS safety controller
and Ethernet network. Prevent unintended start-up of equipment during
connection of an Ethernet interface module.
3.2.1 Steps for mounting the modules
The MELSEC-WS safety controller is only suitable for mounting in a
control cabinet with at least IP 54 degree of protection.
While supply voltage is applied, modules must not be plugged to nor be
removed from the MELSEC-WS safety controller.
To ensure full electromagnetic compatibility (EMC), the DIN mounting rail
must be connected to functional earth (FE). Additionally connect all
network cable shields directly at the control cabinet entrance to a common
FE ground line.
In a MELSEC-WS safety controller, the WS0-CPU0 or WS0-CPU1 module is
positioned at the extreme left.
The two optional network modules follow directly to the right of the CPU module.
Connect further MELSEC-WS safety I/O modules (e.g. WS0-XTIO or WS0-XTDI)
onto the right side of the network modules and any additional safety relay output
modules (WS0-4RO) to the extreme right of the entire MELSEC-WS safety
controller.
Mount the modules in accordance with EN 50274.
The modules are located in a 22.5 mm wide modular system for 35 mm DIN rails
according to EN 60715.
Ensure that suitable ESD protective measures are taken during mounting.
Otherwise the FLEXBUS+ backplane bus may be damaged.
The connection between the modules is effected by means of the plug
connection integrated in the housing. Take into account that, when replacing a
module, the MELSEC-WS modules have to be pushed approx. 10 mm apart
before the corresponding module can be removed from the DIN rail.
Take suitable measures to ensure that foreign matter does not penetrate the
connector openings, in particular that of the memory plug.
