8.5.2 T-shaped branch communication specification list
The table below shows the communication specification in T-shaped branch connection.
For communication specification not shown in the table below, refer to Section 4.4.
Table 8.2:
Item Specification Remarks
Transmission speed 625kbps 156kbps 10, 5 and 2.5 Mbps are not available.
Maximum main line
length
100m 500m
The value indicates the cable length
between terminal resistors.
The cable length of T-shaped branch lines
(branch length) is not included.
Maximum branch line
length
8m
The value indicates the cable length per
branch line.
Total branch line
length
50m 200m
The value indicates the total length of all
branch lines.
Maximum number of
modules connected to
branch line
6 modules/branch line
The number of connected modules
conforms to the CC-Link specification.
Connection cable
Dedicated CC-Link cable
(Examples: FANC-SB, CSFV-SLAB,
100ZCLK-SB-20AWGX3C)
• 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.)
Terminal resistor
(connection method) Connect a terminal resistor (110
Ω
) packed
together with master module.
For the connection method, refer to Section
8.4.
T-shaped branch
terminal block/
connector
• Terminal block: Commercial one
• Connector:
Connector for FA sensor NECA4202
(IEC947-5-2) or its equivalent is
recommended.
(NECA: THE JAPAN ELECTRIC
CONTROL EQUIPMENT INDUSTRY
ASSOCIATION Standards)
• When wiring cables to the main line, strip
as little of the insulation as possible.
