website (www.cc-link.org).
General-purpose hub
*1 When using a TSN hub, use the RJ71GN11-T2 with a firmware version of "05" or later.
A switching hub can be used for cascade connection.

Precautions
• Since there are different restrictions for system configuration using a TSN hub and system configuration using a general-
purpose hub, setting with an engineering tool is required. ( Page 25 SYSTEM CONFIGURATION)
• Do not configure a ring topology when modules are connected to a switching hub. Doing so, all stations will fail and data
links cannot be performed.
• Incorrectly configured ring topology can be detected an error on the CC-Link IE TSN/CC-Link IE Field diagnostics and
event history. However, if the system is configured with a switching hub, the error may not be detected.
