C14: Slave Copper/Fiber Main Ring Connections and DIO Sub-ring with DIO Clouds

Predefined Configuration File Name

C14_Slave_RIOMainRingFxTx_DIOSubRingTx_DIOCloudsVx.xx.cfg, where Vx.xx references the version number of the file.

Use of this Predefined Configuration

With this predefined configuration downloaded, a can be used to make the transition from copper to fiber or back to copper from fiber on the main ring. The switch can also support a distributed I/O sub-ring.

With this predefined configuration, use 2 DRSs — one installed with this slave predefined configuration and the other installed with the corresponding master predefined configuration (C13) — to provide a redundant connection between the main ring and a distributed I/O sub-ring. The master DRS passes data between the main ring and the distributed I/O sub-ring. If the master DRS becomes inoperable, the slave DRS takes control and passes data between the main ring and the remote I/O sub-ring.

NOTE: When a master slave becomes inoperable, a slave DRS assumes the primary role in less than 50 ms. Refer to the Comparison of Master/Slave Configuration and Auto Configuration to determine what roles the master and slave DRSs resume if the master DRS becomes operational again.

NOTE:

DRS inner ports are the 2 ports on the switch that are connected to the main ring. When using 2 DRSs, connect the designated master inner ports to the designated slave inner ports.

For copper port master and slave DRS redundant configurations, the inner ports are port 2 for the main ring and port 6 for a sub-ring.
For copper/fiber port master and slave DRS redundant configurations, the inner ports are port 3 for the main ring and port 6 for a sub-ring.

If you are using a single DRS but plan to convert to redundant configurations in the future, make a note of these port configurations to minimize any schematic changes required because of the conversion.

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 distributed I/O devices include an embedded dual-port Ethernet switch and support the RSTP protocol. (In this manual, Modicon STB islands with STB NIP 2311 network interface modules are used for illustration.)

The predefined configuration described here can be used with either of 2 DRS types:

A TCSESM063F2CU1 ConneXium extended managed switch, which supports multi-mode fiber cable
A TCSESM063F2CS1 ConneXium extended managed switch, which supports single-mode fiber cable

Both switches have 2 fiber ports and 6 copper ports.

With single-mode fiber cable, you can achieve distances on the main ring up to 15 km. With multi-mode fiber cable, you can achieve distances up to 2 km.

You cannot use a redundant pair of DRSs to connect a sub-ring to another sub-ring.

Do not connect any devices between the master DRS and the slave DRS on the main ring or the sub-ring. Install the DRSs next to each other — within 100 m.

Port Connections

The top fiber port (port 1) makes the redundant connection to the fiber cable on the main ring (A). The other fiber port (port 2) is disabled; do not connect to this port.

The top left copper port (port 3) makes the redundant connection to the copper cable on the main ring (B). Copper ports 5 and 6 are used to connect to the distributed I/O sub-ring (C).

Ports 4 and 7 can be used for other purposes. 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.

Port	Type	Description
1	FX	fiber main ring redundant connection
2	FX	disabled fiber port; do not use
3	100Base-TX	copper main ring redundant connection
4	100Base-TX	a distributed I/O cloud connection
5	100Base-TX	distributed I/O sub-ring redundant connection
6	100Base-TX	distributed I/O sub-ring redundant connection
7	100Base-TX	a distributed I/O cloud connection
8	100Base-TX	port mirroring connection

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.
