6 INSTALLATION AND CONNECTION
6.4.2 T-branch communication specifications list
The following describes the communication specifications for T-branch connection.
For communication specifications not listed below, refer to Section 3.2.
Item Specification Remarks
Transmission speed 625 kbps 156 kbps 10 M/5 M/2.5 Mbps are not allowed.
Maximum length of the main line 100 m 500 m
Indicates the length of the cable between terminating
resistors. The length of T branch cable (branch line
length) is not included.
Maximum length of the branch line 8 m Indicates the overall cable length per branch.
Overall branch line length 50 m 200 m Indicates the total length of all branch cables.
Maximum number of connected
stations on the branch line
6 stations per branch
The total number of connected stations depends on the
CC-Link specifications.
