CHAPTER 2
This chapter describes a CC-Link/LT system configuration.
2.1

Overall Configuration

To one master station, up to 64 remote stations can be connected when the following conditions are met.
Transmission speed
Station-to-station distance
Maximum number of modules on a
branch line
Trunk line length
T-branch interval
Maximum length of a branch line
Overall branch line length
T-branch

*2
*3
● Remote stations need not to be connected in station number order.
● Remote station numbers are not necessarily consecutive. (Leaving any station number out does not cause a data link
