7 - 9
This section explains how to connect the master module, local modules, standby
master module, remote modules and intelligent device modules with the CC-Link
dedicated cables.
(1) CC-Link cables can be connected from any station number.
(2) Connect the supplied "terminal resistors" to each module at both ends of the CC-
Link system.
Connect the terminal resistors between "DA" and "DB".
(3) The terminal resistors to be connected vary depending on the types of cables
used in the CC-Link system.
Cable type
CC-Link dedicated cable
Version 1.10 compatible CC-Link dedicated cable
CC-Link dedicated high-performance cable
(4) The master module can be connected at points other than both ends.
(5) Star connection is not allowed.
(6) The connection method is shown below.

IMPORTANT
The CC-Link dedicated cable and CC-Link dedicated high performance cable
cannot be used together. If they are used together, proper data transmission
cannot be guaranteed.
POINT
Connect the shielded wire of the CC-Link dedicated cable to "SLD" of each module,
and ground both ends of the shielded wire using D type grounding via "FG".
The SLD and FG are connected within the module.
