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, distributed I/O clouds may not provide sufficient cable redundancy. With a Quantum EIO network, you can deploy distributed I/O in a way that takes advantage of the redundant cabling architecture. The following predefined configuration enables you to support distributed I/O devices on sub-rings. A distributed I/O 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 I/O devices, and handles packets from a remote I/O network before handling packets relating to distributed I/O devices.
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 remote I/O modules in a distributed I/O sub-ring. Only distributed I/O devices with a dual-port embedded Ethernet switch and RSTP protocol support can be used. (In this manual, distributed I/O devices 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 distributed I/O sub-ring to the main ring.
Ports 3, 4, and 7 can be used to connect distributed I/O clouds to the Quantum EIO 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.

NOTE: When you download this DRS predefined configuration file to a switch, the file provides a set of operating parameters that enable the switch to operate with high efficiency in the specified architecture.
Do not adjust the configuration parameters or alter the port usage from what is shown above. Changing the configuration parameters or the port assignments can compromise the effectiveness and accuracy of the switch and the performance of the remote I/O network.
You can enable/disable port mirroring and change the selection of the source ports that you want mirrored. Port mirroring is disabled by default. The destination port is set to port 8, and ports 1-7 are selected as source ports. Do not change the destination port. When using port mirroring, select the ports, for which you want to analyze the traffic, as the source ports. When you finish troubleshooting, disable port mirroring.
