Advanced Network Configuration dialog box

Use the
Advanced Network Configuration
 dialog box to configure advanced network properties. The dialog box is only available for controllers with an embedded Ethernet port.
TIP: To open the Advanced Network dialog box:
  1. On the
    Online
    toolbar, click the
    Controller Properties
     icon.
  2. On the
    Controller Properties
     dialog box, click the

     tab, and then click
    Advanced
    .
For more information on how to configure the advanced network properties, refer to the EtherNet/IP Device Level Ring Application Technique (publication ENET-AT007).
Parameter
Description
Network Topology
Displays the current network topology as either:
  • Linear/Star
  • Ring
Active Ring Supervisor
Displays the IP Address or MAC Address of the active ring supervisor.
Active Supervisor Precedence
Displays the precedence currently assigned to the active ring supervisor.
Supervisor Mode
Displays whether the controller's Supervisor Mode is enabled or disabled.
Supervisor Status
Displays the status of the supervisor when
Supervisor Mode
 is enabled.
  • Active
     - The controller is the Active Ring Supervisor.
  • Backup
     - The controller is the backup ring supervisor.
  • Cannot support current Beacon Interval or Timeout
     - The controller cannot support the beacon interval or timeout values of the current Active Ring Supervisor.
Supervisor Precedence
Specifies the supervisor precedence number when
Supervisor Mode
 is enabled.
Acceptable values: 0 to 255.
When multiple nodes are enabled as supervisor, the node with the highest precedence value is assigned as the active ring supervisor; the other nodes automatically become back-up supervisors. We recommend the following:
  • Configure at least one back-up supervisor node.
  • Set the desired Active Ring Supervisor with a relatively high supervisor-precedence value compared to the back-up node(s).
  • Keep track of the supervisor-precedence values of a network.
Beacon Interval
Specifies the frequency at which the active ring supervisor transmits a beacon frame through both of its ring ports. Available when
Supervisor Mode
 is enabled.
Acceptable values: 100 to 100000.
Beacon Timeout
Specifies the amount of time that supervisor or ring nodes wait before timing out the reception of beacon frames and taking appropriate action. Available when
Supervisor Mode
 is enabled.
The beacon timeout value must be at least 2 times the beacon interval value but not exceed 500,000.
Ring Protocol VLAN ID
Specifies the VLAN ID to use in the ring protocol message when
Supervisor Mode
 is enabled.
Acceptable values: 0 to 4094.
