Module Wiring with Dedicated CC-Link Cables
This section describes the connection method of dedicated CC-Link cables.
•
The cables can be connected without regard to the station number.
•
Make sure to connect a terminal resistor (offered as an accessory of the module) between
the terminals DA and DB in modules at both ends.
•
In the CC-Link system, the terminal resistor to be connected varies depending on the used
cable.
-
When a dedicated CC-Link cable is used: 110
Ω
, 1/2 W (brown, brown and brown)
-
When a dedicated high-performance CC-Link cable is used: 130
Ω
, 1/2 W (brown,
orange and brown)
•
The master module can be connected besides to the both ends.
•
Star connection is not allowed.
•
The figure below shows the connection method.
Important
Make sure to use only one type of cable (dedicated CC-Link cables OR dedicated
CC-Link high-performance cables).
If both types of cables are used together, normal data transmission cannot be
guaranteed.
Point
The shielded dedicated CC-Link cable should go through the terminals SLD and FG
in each module, and both ends should be grounded (Class D = 100
Ω
or less).
The terminals SLD and FG are connected each other inside the module.
