IMPORTANT Out of the box the supervisor capable devices have their supervisor function disabled so they are ready to participate in either a linear star network topology or as a ring node on an existing DLR network Ina DLR network you must configure at least one of the supervisor capable devices as the ring supervisor before physically closing the ring If not the DLR network does not work You can use the DIP switches on a 1783 ETAP tap so the tap functions as a supervisor at power up For more information on how to use the 1783 ETAP DIP switches see Use DIP Switches on page 56 Rockwell Automation Publication ENET APOOSF EN P October 2014 15 Chapter 1 16 EtherNet IP Embedded Switch Technology Overview Active Ring Supervisor When multiple nodes are enabled as supervisor the node with the numerically highest precedence value becomes the active ring supervisor the other nodes automatically become back up supervisors The ring supervisor provides the following primary functions e Verifies the integrity of the ring e Reconfigures the ring to recover from a single fault e Collects diagnostic information for the ring Back up Supervisor Node At any point in time there is one active supervisor on a DLR network We recommend that you can configure at least one other supervisor capable node to act as a back up supervisor During normal operation a back up supervisor behaves like a ring node If the active supervi
