Supported ABB solutions

The REX640 protection relay together with the Substation

Management Unit COM600S constitutes a genuine IEC 61850

solution for reliable power distribution in utility and industrial

power systems. To facilitate the system engineering, ABB’s

relays are supplied with connectivity packages. The

connectivity packages include a compilation of software and

relay-specific information, including single-line diagram

templates and a full relay data model. The data model includes

event and parameter lists. With the connectivity packages, the

relays can be readily configured using PCM600 and integrated

with COM600S or the network control and management

system MicroSCADA Pro.

REX640 offers native support for IEC 61850 Edition 2 including

binary and analog horizontal GOOSE messaging. In addition, a

process bus enabling sending and receiving of sampled values

of analog currents and voltages is supported.
