Structure Of Unicast Mode - Mitsubishi Electric MELSEC iQ-R Series User Manual

Structure of unicast mode

This mode indicates the availability of connection with a network configuration device when "Communication Mode" under
"Application Settings" is set to "Unicast".
When the communication speed for the master station is set to 1Gbps
This mode indicates the availability of connection with a network configuration device when "Communication Speed" of the
master station is set to "1Gbps".

*1 For a slave station with a communication speed of 100Mbps, set "Communication Period Setting" to "Low-Speed" (16 times).
*2 A connection cannot be established if the total cyclic data size of all slave stations on the 100Mbps device side exceeds 2K bytes for
devices that form a boundary between the communication speed of 1Gbps and 100Mbps. ( Page 56 Calculation of the total cyclic
data size)
*3 If the device on the master station side is a CC-Link IE TSN Plus module, only P1 can be connected.
*4 If the device on the end side is a CC-Link IE TSN Plus module, only P1 can be connected.
*5 If the device on the master station side is a CC-Link IE TSN Plus module, P2 can be connected without passing through a switching hub.
*6 Connection is not possible if the device on the master station side is a CC-Link IE TSN Plus module.
*7 If the device on the master station side is a CC-Link IE TSN Plus module, only P2 can be connected.
■Precautions
When a TSN hub is used, check the TSN hub specifications on the CC-Link Partner Association website (www.cc-link.org).
