Predefined Configuration File Name
C2_RIOMainRing_DIOSubRing_DIOCloudsVx.xx.cfg, where
Vx.xx references the version number of the file.
Use of this Predefined Configuration
In some applications, DIO clouds may not provide sufficient cable redundancy. With an M580 network, you can deploy distributed equipment in a way that takes advantage of the redundant cabling architecture. The following predefined configuration enables you to support distributed equipment on sub-rings. A DIO sub-ring restores communications in the event of a broken wire or inoperable device on the sub-ring.
NOTE: Each DRS applies a lower priority to distributed equipment, and handles packets from an RIO network before handling packets relating to distributed equipment.
Devices Supported by this Predefined Configuration
The DRS predefined configuration described here is for a TCSESM083F23F1 ConneXium extended managed switch, which has 8 copper connection ports and no fiber ports.
You cannot use RIO modules in a DIO sub-ring. Only distributed equipment with a dual-port embedded Ethernet switch and RSTP protocol support can be used. (In this manual, distributed equipment are represented by Modicon STB islands with STB NIP 2311 network interface modules.)
Predefined Port Connections
Use the 2 top ports (shown as 1 and 2 below) for the main ring connections. Use ports 5 and 6 to connect the DIO sub-ring to the main ring.
Ports 3, 4, and 7 can be used to connect DIO clouds to the M580 system. Port 8 is reserved for
port mirroring, i.e., for monitoring the status of the ports you previously selected in the switch’s port mirror web page.
NOTE: The default configuration of port 8 has port mirroring disabled.
This table describes the functionality of the ports in the above illustration:

Except when enabling or disabling ports that are not connected to either a main ring or a sub-ring, do not adjust the configuration parameters or alter the port usage in the predefined configuration file. Changing the configuration parameters or the port assignments can compromise the effectiveness and accuracy of the switch, as well as the performance of the RIO network.
Port mirroring is disabled by default. If you enable port mirroring, you can select the ports on which you want to analyze traffic as the source ports. Ports 1-7 can be selected as source ports. Port 8 is the destination port, and it cannot be changed.
