[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.

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.
14
Use a cable of the maximum
possible size and keep the wiring
length at a minimum.
Metallic enclosure
* Provide a dedicated class D grounding (Third class).
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.
15
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.

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.

(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.
