*1. For specifications of local station, please refer to the “MELSEC iQ-F FX5 User's Manual (CC-Link IE TSN) (SH(NA)-082215ENG).
*2. System configuration mixing 1Gbps devices and 100Mbps devices will be supported in the future.
*3. Includes a master station.
*4. Line topology and star topology can be mixed.
Network topologies
■Line topology (twisted-pair cable)
Network topology ideal for system configurations with high-speed/high-performance control
- High-speed communication is possible as the system is configured with CC-Link IE TSN-compatible slave devices only
- Easier system configuration without an Ethernet switch
- Ideal for highly accurate motion control systems
■Star topology (twisted-pair cable)
Network topology ideal for flexible system configurations
- Easily realizes distributed arrangement of slave devices depending on Ethernet switch specifications
- Easy to change/rearrange equipment or system configuration
- Ideal for general production line control systems
■Ring topology (twisted-pair cable)
Network topology ideal for systems requiring high reliability*5
- Maintain data communications with normal stations even if a cable is disconnected or an error occurs in one of the slave stations
- Configuration without requiring an Ethernet switch
- Ideal for continuously operating control system
*5. Please refer to the relevant product manual for confirming if ring topology is supported. Mixing of star topology and line topology is not supported.
Certified class
CC-Link IE TSN certifies nodes and switches to a specific class level according to its functionality and performance classification. Products can be classified as either class A or B. For the certified classification of each product, please check the CC-Link partner association website or the relevant product catalog or manual. Supported functions and system configuration may differ according to the certified class of products used. For example, products compatible with certified class B are necessary to configure a high-speed motion control system. For details of configuring systems with both class A and class B devices, please refer to relevant master product manual.
System configuration
- Synchronous accuracy of a system varies relative to the combination of connected devices and switches certification class
- Use class B Ethernet switch when configuring a star topology with class B devices
- Use class B devices when configuring a system within ±1 μs high-accuracy synchronization, connect class A devices to a separate branch line from class B devices (for details of system configuration, please refer to relevant master product manual)
