1. Outline
1.1 CC-Link gateway unit
CC-Link Gateway Unit (hereinafter, referred to as CC-Link gateway or gateway unit) is a unit to connect the
network of CC-Link communication protocol for an upper programmable controller (hereinafter, referred to as
PLC) and SIO communication network (Modbus communication protocol) for a controller (for robo-cylinder)
which is a sub-network.
Physical standard for SIO communication network is RS-485, and slave addresses on this network are 1-16.
All data exchanged between the CC-Link and the Modbus protocol communication network are once stored in
the internal memory of the gateway unit, and transmitted to CYCLIC. The gateway unit is handled from the
PLC side as a remote I/O.
Adaptable controllers are PCON-SE, ACON-SE, SCON and ERC2-SE.
* Gateway is communication terminology, and is equipment which mutually converts data of which media and
protocols are different on networks, and allows for communication.

1.2 What is CC-Link
(1) System of FA communication
For FA communication, communication specifications depend on equipment on the communicating end,
content of information and its purpose, however, are roughly divided into information level, controller
level and field level as shown in the following diagram.
(2) Information level
This is mainly used to transmit production information to an information terminal, and is referred to as
“PLC upper network.” Ethernet is mostly used for this level.
(3) Controller level
This frequently handles real time information for a production line, and is referred to as “Network
between PLCs.”
(4) Field level
This is referred to as “PLC lower network,” and is mainly used to save wiring for a control system of
which one controller is in charge, and is positioned as “Wiring save communication.”
This level is largely classified into device level and sensor level.

(5) CC-Link
CC-Link has become wide spread mainly for FA as an open network for device level. Communication
specifications are open to the public, therefore, equipment in compliance with CC-Link can be
communicated without a program regardless of manufacturer.
Presently, CC-Link is spread and operated by CC-Link association (CLPA: CC-Link Partner Association),
which is a non-profitable organization.
Main features are as follows.
[1] Highly perfected saved wiring communication which has realized complete multi-vendor connection.
[2] This is a unified standard, therefore, it can be used even overseas.
[3] Since slave equipment is handled as a PLC remote I/O to which CC-Link unit is installed,
communication can be made without a particular program.
[4] Since line efficiency is high, communication with high-speed response can be made.
※ For details of CC-Link, refer to Operation Manuals of the master unit and the PLC to be installed.
Use this Operation Manual together with the Operation Manual of the controller to be connected.
This CC-Link gateway cannot be used in ways other than those for which this Operation Manual expressly
allows. Further, do not perform setting and wiring other than those for which this Operation Manual
expressly allows.

1.4 Features
For CC-Link gateway, operation modes of the following four patterns can be selected.
(1) Position data limit designation mode
Only position data can be directly designated, and the maximum connecting axis number totals 14
axes.
Further, various status signals can be input and output, and present position data can be read.
Speed, acceleration and deceleration can be set for parameters for each axis as fixed values.
(2) Position No. designation mode
This is a mode to designate No. of position table for operation, and the maximum connecting axis
number totals 14 axes.
Position data, speed, acceleration and deceleration are input into the position data table of each axis in
advance. Input and output of various status signals and completed position No. can be read.
(3) Positioning data designation mode
This is a mode to directly designate position data for operation, and there are two patterns of normal
positioning and push operation.
[1] Normal positioning mode
This mode directly designates speed, acceleration and deceleration in addition to position data, and
the maximum connecting axis number totals 7 axes.
Further, input and output of various status signals and present position data can be read.
[2] Push operation mode
Push operation can be performed, and the maximum connecting axis number totals 3 axes.
This is a mode in which direct designation of current limit value (%) and positioning width for push is
added to the normal positioning mode.
(4) Simple direct value/Position No. designation mode
This mode can mix position No. designated axis and simple direct value designated (position data is
designated by numeric value, and the other movement data is designated by position table) axis.
Axis number is assigned from position No. designated axes, and subsequently, it is necessary to assign
the number to simple direct value designated axis. Depending on the size of the assignment area,
there is a Large pattern (88 words respectively for input and output), Middle pattern (68 words
respectively for input and output) and Small pattern (34 words respectively for input and output), and
the maximum connecting axis number totals 16 axes.
This Manual only describes content which can be controlled by using the Gateway unit. Content of this Manual
takes precedence over content of the Operation Manual for the controller. For detailed contents of functions,
parameter settings and alarms, refer to the Operation Manual for the controller.

[9] Port switch
This is a switch to enable the connector (T.P.) for teaching box and personal computer (PORT
ON=Communication start).
When connecting and disconnecting the teaching box and the communication cable connector for
personal computer supporting software, turn OFF this switch. When using this switch, turn ON after
connecting the connector.
(Also pay attention to signal status of the port switching input [4].)
For communication rate between the teaching box, personal computer supporting software and the
CC-Link gateway, up to 115.2kbps can be set. And, the communication rate between the CC-Link
gateway and the controller is fixed to 230.4kbps.
When the PORT is ON, the CC-Link communication does not become abnormal, however, data
communication for SIO communication stops. Therefore, output signal (data) from the PLC is not
outputted to the controller, and input signal (data) from the controller keeps a value immediately before
PORT was ON.
PORT ON status signal (TPC) is outputted from the CC-Link gateway to the PLC, therefore, performs
processing such as interlock if necessary.
[10] Connector for teaching box and personal computer
This is a connecting connector for the teaching box and personal computer.
[11] Power supply input connector
This is a connecting connector for the power supply (24V DC) for the CC-Link gateway.

3. Installation and Noise Elimination
Pay sufficient attention to the installation environment.
3.1 Installation Environment
a. Since the gateway unit is not dust-proof or waterproof (oil proof), avoid using the gateway unit in a
place subject to significant dust, oil mist or splashes of cutting oil.
b. Do not expose the gateway unit to direct sunlight or radiating heat from a large heat source such as
heat treatment furnace.
c. Use the gateway unit in an environment free from corrosive or inflammable gasses, under a
temperature of 0 to 40°C and humidity of 85% or less (non-condensing).
d. Use the gateway main body where it will not receive any external vibration or shock.
e. Prevent electrical noise from entering the gateway main body or its cable.
3.2 Power Supply
The power supply specification is 24V DC±10%. （Supply current: 300mA max.）
3.3 Noise Elimination and Grounding
a. Installation of gateway unit main body
Directly fix the gateway unit main body to the metallic enclosure with screws for connection.
* Provide a dedicated class D grounding (Third class).
Use a cable of the maximum
possible size and keep the wiring
length at a minimum.
Metallic enclosure
15
b. Precautions regarding wiring method
Separate the communication lines for the gateway unit and the wiring for the CC-Link
communication line from high-power lines such as a cable connecting to a power circuit. (Do not
bundle together wiring for the communication lines with high-power lines or place them in the same
cable duct.)
c. Noise sources and elimination
Among the numerous noise sources, solenoid valves, magnet switches and relays are of particular
concern when building up a system. Noise from these sources can be eliminated by implementing
the measures specified below.
[1] AC solenoid valves, magnet switches and relays
Measure: Install a surge absorber in parallel with the coil.
[2] DC solenoid valves, magnet switches and relays
Measure: Install a diode in parallel with the coil. Determine the diode capacity in accordance
with the load capacity.
← Point
Install a surge absorber to each
coil over a minimum wiring
length. Installing a surge
absorber to the terminal block or
other part will be less effective
because of a longer distance
from the coil.
In a DC circuit, connecting a diode in reverse polarity
will damage the diode, internal parts of the controller
and/or DC power supply, so exercise sufficient caution.
16
3.4 Installation
Design the control box size, installing position of the gateway unit and cooling method of the control box in
such a way that the temperature around the gateway unit will not exceed 40°C.
Install the gateway unit vertically on a wall, as shown below, and provide a minimum clearance of 50mm
above and below the gateway unit and a minimum clearance of 100mm on the front for wiring.
For lateral installation such as installing multiple gateway units side by side, secure a sufficient space so that
the gateway unit is easily installed and removed.
If affection of heat or noise is a concern, take the measure into account.

Reference Outline of CC-Link network configuration
For details of the CC-Link, refer to the Operation Manual for the master side (PLC). This section
describes a point for network wiring.
The following diagram shows an example of network connection.
(1) Equipment connected by the CC-Link is referred to as a station, and 0 to 64 can be set as a station No.
The master station and slave station can be placed on any position.
(2) Connection is made by a multi-drop method directly branching at each station, and a T-branch using
commercially available terminal block, etc., is allowed.
(3) Use a dedicated shielded 3-core twisted paired cable as a cable.
The dedicated cable is as follows.
Color Signal type
Blue Communication line A (DA)
White Communication line B (DB)
Yellow Communication ground line (DG)
- Shield (SLD)
(4) It is necessary to install terminal resistors on both ends of the CC-Link system. The terminal resistor is
connected between “DA” and “DB,” however, it differs with the cable being used.
(5) Communication rate is restricted by network length (total branch length, network maximum length).
CAUTION
Set the GND (ground) level of the power supply for each controller connected to the gateway to the power
supply for the gateway.

The connector port for the teaching box and personal computer can be also turned ON/OFF by an
external signal other than the ON/OFF signal from the port switch on the gateway unit main body.
Further, since the contact signal from the emergency stop pushbutton switch on the teaching box is
outputted to the outside while the port is ON, this signal can be incorporated into the emergency stop
circuit for the whole system.

a terminal resistor to both
ends of the CC-Link
system (between DA and
DB), therefore, check the
Operation Manual for the
master side (PLC).

CAUTION
1. Provide a communication path via a bus connection, and be sure to connect a terminal resistor at the
end. A terminal resistor is incorporated into the gateway unit side, therefore, it is unnecessary to connect
it.
2. The communication cable should be supplied by customer. If the recommended communication cable
is not used, use an electric wire size AWG22.

a. Detail Connection Diagram
The diagram below shows the details of the SIO communication connection. The controller link cables
are optionally prepared, but the communication main line must be prepared by the customer.
b. Preparation of Communication Main Line
[1] Strip off approx. 15-20mm of the sheath
from the two-paired shielded cable.
[2] Install the cable protective tube.
[3] Insert three cables into the cable insertion
hole of the connector without stripping off
the envelope of the conductors.
[4] Pressure-weld the cable press-fit housing
with the cables inserted from above.
[5] Heat-treat the cable protective tube.
Pin numbers of e-CON connector
Be sure to insert the terminal resistor (220Ω, 1/4W) into the end of the communication main line.
