Data Link Procedure 8
Remarks
10, 5 and 2.5 Mbps are not available.
The value indicates the cable length
between terminal resistors.
The cable length of T-shaped branch lines
(branch length) is not included.
The value indicates the cable length per
branch line.
The value indicates the total length of all
branch lines.
The number of connected modules
conforms to the CC-Link specification.
• Dedicated high-performance CC-Link
cables (example: FANC-SBH) are not
available.
• Cables produced by different
manufacturers are not available at the
same time.
(For manufacturers, refer to brochures.)
For the connection method, refer to Section
8.4.
• When wiring cables to the main line, strip
as little of the insulation as possible.
