Connectable Devices (For Multicast Mode) - Mitsubishi Electric MELSEC iQ-R Series User Manual

Connectable devices (for multicast mode)

This section describes the connectable devices when "Communication Mode" under "Application Settings" is set to
"Multicast".
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".
: Connection available, : Connection available via a switching hub, : Connection not available
S: TSN hub available
H: General-purpose hub available

*1 For a device station with a communication speed of 100Mbps, set "Communication Period Setting" to "Low-Speed".
*2 When the device is connected on the end side via the switching hub as shown below, communication may not be possible depending on
the type of the device.
The communication will be enabled by configuring settings with the switching hub so that the multicast frame (with multicast MAC
address 09:00:70:00:10:02 and 09:00:70:00:10:05) will not be transferred to the ports specified below.
Connection structure that cannot be communicated
Device stations with different communication speeds of 1Gbps and 100Mbps
coexist.
A local station and Ethernet device coexist.
The local station and CC-Link IE TSN Class A remote station are mixed.
*3 For a local station or remote station of a device on the master station side, use a device supporting the multicast filter. ( Manual for
the device used)
*4 A connection cannot be established if the total cyclic data size of all device stations on the 100Mbps device side exceeds 2K bytes. This
includes the devices with a communication speed of 100Mbps that form a boundary between the communication speed of 1Gbps and
100Mbps. ( Page 64 Calculation of the total cyclic data size)
Precautions
When a TSN hub is used, check the TSN hub specifications on the CC-Link Partner Association website (www.cc-link.org).
