Introduction
Use the Switch properties to perform these tasks:
NOTE: The Ethernet communication module supports only the Ethernet II frame type.
Access the Switch Properties
View the Switch properties for the BMENOC0321 module:
Step
Action
1
Open the DTM Browser and view the Channel Properties for the module.
2
Expand (+) the Channel Properties to see the Switch page.
3
Select the Switch page to see the configurable properties.
NOTE: The Ethernet communications module supports only the Ethernet II frame type.
Properties
Configure Switch properties to conform to your application:
Column
Description
Port
This read-only column shows the Ethernet ports that are connected to the module’s internal switch (ETH 1, ETH 2, etc.) and the backplane port.
Enabled
Scroll to enable (Yes) or disable (No) a port.
NOTE:
  • The port is disabled by default.
  • When you enable IPsec, the DTM automatically disables the backplane Ethernet port on the BMENOC0321. This isolates the IPsec network (control room network) from the device network. (Refer to the table for using different services and protocols.)
Baud Rate
Select a baud rate for the enabled port (see below).
The baud rate for the enabled backplane port is 100 Mbits/sec Full duplex.
Select a baud rate for an enabled Ethernet port:

ETH 2, ETH 3
Auto 10/100/1000Mbits/sec (default)
1000 Mbits/sec Half duplex
1000 Mbits/sec Full duplex
100 Mbits/sec Half duplex
100 Mbits/sec Full duplex
10 Mbits/sec Half duplex
10 Mbits/sec Full duplex
Backplane Port
100 Mbits/sec Full duplex
NOTE: Schneider Electric recommends this default baud rate. With this setting, connected devices perform auto-negotiation and thereby determine the fastest common transmission rate and duplex mode.
NOTE: Cable recommendations:
To connect a BMENOC0321 control network module to a control network in a Modicon M580 system, Schneider Electric recommends the use of these cables:
  • 10/100 Mbps: For a communications link less than or equal to 100 Mbps, use CAT5e or CAT6 copper shielded twisted four-pair cables.
  • 1000 Mbps: For a communications link less than or equal to 1000 Mbps, use only CAT6 copper shielded twisted four-pair cables.
