5.2.2 Precautions for wiring CC-Link Ver. 1.10-compatible cable
(1) Wiring precautions
(a) Usage of CC-Link cables
The CC-Link Ver. 1.10-compatible 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 CC-Link Ver.
1.10-compatible 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 CC-Link Ver. 1.10-compatible cable
Shut off the external power supply for the system in all phases.
(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.
