7.5 Module Wiring with CC-Link Dedicated Cable
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) Ver.1.10-compatible CC-Link dedicated cables, CC-Link dedicated cables
master module, remote modules and intelligent device modules with the CC-Link
dedicated cables.
(1) Ver.1.10-compatible CC-Link dedicated cables, CC-Link dedicated cables
(Ver.1.00), and CC-Link dedicated high-performance cables cannot be used
together. If used together, correct data transmission will not be guaranteed.
together. If used together, correct data transmission will not be guaranteed.
(2) CC-Link cables can be connected from any station number.
(3) Connect the shielded wire of the CC-Link dedicated cable to "SLD" of each
module, and ground both ends of the shielded wire to the protective ground
conductor via "FG".
The SLD and FG are connected within the module.
conductor via "FG".
The SLD and FG are connected within the module.
(4) Connect the "terminating resistors" supplied with each module at both ends of the
CC-Link system.
Connect the terminating resistors across "DA" and "DB".
When a T-branch system is configured, some restrictions are applied to the use of
the A(1S)J61BT11/A(1S)J61QBT11 is used as the master station. Refer to
Section 7.6.1 for details.

(5) The terminating resistors to be connected vary depending on the cable type used
in the CC-Link system.

(6) For the terminal block screws, M3.5 screws are used.
(7) Use a solderless terminal and wire described in the following table for the terminal
block. Tighten the solderless terminal within the tightening torque range.
Use a UL-listed solderless terminal and a tool recommended by the manufacturer
of the solderless terminal for processing. A sleeved solderless terminal cannot be
used.
