When using the tap in a DLR network, consider whether the tap will be a ring supervisor. By default, the tap is configured to be a non-supervisor ring node. Use one of these

methods for controlling supervisor functionality:

• Use RSLinx Classic software or the Studio 5000 Logix Designer application to set the Ring Supervisor mode and other supervisor-related parameters. This is the

default method. If you choose this option, follow the procedures in the online Help that accompanies the software to enable Ring Supervisor mode.

• Use the DIP switches to automatically enable Ring Supervisor mode with the current supervisor-related parameters stored in the tap’s memory.(a) See Set the DIP

Switches on page 9 for additional information.

Use these precautions when configuring a DLR network:

• Make sure that at least one node is acting as supervisor before connecting the last link of a DLR network and physically closing the ring.

• Do not connect nodes that do not support a DLR as members of the ring

This product is intended to be mounted to a well-grounded mounting surface, such as a metal pane or DIN rail.

Configure the Ethernet port on the device that you connect to a

tap so that it matches the tap’s speed and duplex settings.

Failure to make the speed and duplex settings of directly

connected devices match may result in higher error rates, or loss

of network connectivity.
