Branch lines
The following table shows the specification for branch lines
(without repeater) with the CC−Link reference cable.
Theme Specification Remarks
Baud rate 625 kBd 156 kBd 10 / 5 / 2.5 MBd not possible.
Maximum length of main
string 100 m 500 m Cabel length between the terminating resistors
without the length of the branch line cables.
Max. branch line length 8 m Total cable length for a branch line.
Max. total length of
branch lines 50 m 200 m Total cable length for all branch lines.
Max. number of slaves
per branch line 6 slaves per branch
line Total number of connectable slaves depends on
CC−Link specification.
Connecting cable CC−Link reference
cable CC−Link high−perfomance cable cannot be used
(e.g. FANC−SBH).
The use of different cables is not possible.
Branch line sub−bases Commercially−avail
able branch line
sub−bases Remove as little insulation as possible from the
cable when it is connected to the main string.
Branch line connectors Recommended
connectors for FA
sensors:
NECA4202
(IEC947−5−2) or
compatible
Distance between
branch lines As desired Distance between branch lines
(branch line sub−bases or branch line connectors).
Length A < 0.3 m Cable length between remote I/Os or remote
device stations.
Length B < 1 m
1)
< 2 m
2)
Cable length for master, local and intelligent device
stations as well as the adjoining stations.
1)
More than 1 m if only remote I/Os and remote device stations are available.
2)
More than 2 m if local or intelligent device stations are available.
