LAN Redundancy

Substation LAN redundancy has been

traditionally accomplished by reconfiguring

the active network topology in case of failure.

Regardless of the type of LAN architecture (tree,

mesh, etc), reconfiguring the active LAN requires

time to switchover, during which the LAN is

unavailable. UR devices deliver redundancy as

specified by PRP-IEC 62439-3. which eliminates

the dependency on LAN reconfiguration and the

associated switchover time. The UR becomes a

dual attached node that transmits data packets

over both main and redundant networks

simultaneously, so in case of failure, one of the

data packets will reach the receiving device with

no time delay.

Multi-Language

UR devices support multiple languages: English,

French, Russian, Chinese, Turkish and German.

These language options are available on the

front panel, in the EnerVista setup software, and

in the product manuals. Easily switch between

English and an additional language on the local

displays without uploading new firmware.
