○Terminating resistor
The terminating resistor to be connected to the CC-Link network depends on the type of cables used.
Please refer to the table below.
Cable type
Communication cable for CC-Link
With socket for BUS IN - PCA-1567720
With plug for BUS OUT - PCA-1567717
CC-Link Ver.1.00 dedicated High-performance cable
Note
•Use the internal terminating resistor only when the SI unit is placed at the end of the CC-Link main
line.
An external terminating resistor should not be used when the internal resistor is used.
The terminating resistor value will be outside the specified range. A network communication error
may occur.
: Refer to page
16 for the switch settings.
Note
•When the CC-Link Ver.1.00 dedicated High-performance cable is used, disable the internal
terminating resistor switch and connect a 130 Ω terminating resistor to the BUS OUT connector.
