ABB The 611 series protection relays support the IEC 61850

Station communication

The 611 series protection relays support the IEC 61850 and

Modbus® communication protocols. Operational information

and controls are available through these protocols. However,

some communication functionality, for example, horizontal

communication between the protection relays, is enabled only

by the IEC 61850 communication protocol.

The IEC 61850 protocol is a core part of the relay as the

protection and control application is fully based on standard

modelling. The relay supports Edition 1 and Edition 2 versions

of the standard. With Edition 2 support, the relay has the latest

functionality modelling for substation applications and the best

interoperability for modern substations. It incorporates also full

support for standard device mode functionality supporting

different test applications. Control applications can utilize the

new safe and advanced station control authority feature.

The IEC 61850 communication implementation supports

monitoring and control functions. Additionally, parameter

settings, disturbance recordings and fault records can be

accessed using the IEC 61850 protocol. Disturbance

recordings are available to any Ethernet-based application in

the standard COMTRADE file format. The relay supports

simultaneous event reporting to five different clients on the

station bus. The relay can exchange data with other devices

using the IEC 61850 protocol.
