Structure With Modules On Cc-Link Ie Tsn - Mitsubishi Electric MELSEC iQ-R Series User Manual

Structure with modules on CC-Link IE TSN

This section describes the system configurations when CC-Link IE TSN Class B devices and CC-Link IE TSN Class A devices
coexist, or when the system consists of modules with CC-Link IE TSN (master station, local stations, remote stations) of CC-
Link IE TSN Class A devices only.
