5.2.2 Precautions for wiring Version 1.10 compatible CC-Link dedicated
cable
(1) Precautions for wiring
(a) Usage of CC-Link cables
The Version 1.10 compatible CC-Link cable cannot be used together
with other CC-Link cables (CC-Link dedicated cable and CC-Link
dedicated high-performance cable)
When used together, normal data communication cannot be expected.
(b) Branching of CC-Link cable
Connect network modules only with CC-Link cables.
Repeater hubs and connectors cannot be used.
(c) Grounding of CC-Link cable
Ground both ends of the shielded wire of the Version 1.10 compatible
CC-Link dedicated cable to the protective ground conductor by
connecting to "SLD" of each network module via "FG".
The SLD and FG are connected within the module.
(d) Connecting a terminating resistor
For the network module at both ends, connect the DA and DB by a
terminating resister (110 , 1/2W) provided with the module.
(e) Connecting/disconnecting Version 1.10 compatible CC-Link dedicated
cable
Shut off all phases of the external power supply for the system.
(2) Connection of cable
(a) Connection method
Connect a blue, white, and yellow cable to the DA, DB, and (DG)
respectively.
In addition, use terminating resistors for the stations at both ends.
