OVERVIEW
• CC-Link IE TSN is a high-speed (1 Gbps) and large-capacity open field network that is based on Ethernet (1000BASE-T).
• The Motion module is an intelligent function module for connecting to CC-Link IE TSN as a master station.
• Wiring of CC-Link IE TSN supports a line topology, star topology, and coexistence of line and star topologies.
• Data can be communicated between the CPU module and the Motion module using the FROM/TO instructions via the
buffer memory. In addition, data can be used in a program by being replaced with data in internal devices, such as X, Y, B,
W, SB, and SW, using the auto refresh function.
Data communication
■Cyclic transmission
Data is periodically communicated among stations on the network using link devices.

■Transient transmission
This type of data communication is used to read/write data from an external device, such as a personal computer or HMI
(Human Machine Interface), to devices in the CPU module of the master station and the remote station via an SLMP.
