5.3.7.2 Standardized communication
The RBX615 unit supports the new IEC 61850 communication
Standard regarding devices in substations.
It also supports standard industrial protocols such as
Modbus® TCP/IP and RTU.
Implementation of the IEC 61850 communication Standard
for substations in the RBX615 unit, includes both vertical
communication (towards the substation network) and
horizontal communication (between the switchgear relays),
among which are communication by means of GOOSE
messaging and parameter setting according to the IEC
61850-8-1 Standard.
5.3.7.3 Virtual GOOSE wiring for interlock
Implementation of the IEC 61850 Standard in the RBX615
relay also includes rapid horizontal relay-relay communication
by means of the station bus. By using GOOSE communication
(Generic Object Oriented Substation Event), the RBX615
relay of the incoming and outgoing lines of a substation
operates in synergy so as to form a stable, reliable and
high speed protection system. Protection based on GOOSE
communication is obtained simply by configuring the relays.
The operating availability of the protection is guaranteed by
constant monitoring of the protection relays and their GOOSE
communication by means of the station bus. Separate
physical wiring is not required for horizontal communication
among the switchgear units.

5.3.7.4 Preventive status monitoring
To guarantee operative availability of the protection, the
RBX615 relay includes a wide range of monitoring functions
to supervise the hardware and software, communication, the
circuit-breaker trip circuit and the circuit-breaker itself.
Depending on the configuration selected, the relay monitors
the state of wear of the circuit-breaker and the time for
loading the circuit-breaker operating mechanism springs.
The relay also measures the operation time and counts the
number of circuit-breaker operations, therefore collecting the
basic information to program suitable maintenance.
5.3.7.5 Rapid configuration and putting into service
Thanks to the standard pre-configurations available, the
RBX615 unit can be configured and put into service extremely
rapidly once the specific application settings have been
defined.
The standard pre-configurations are easily customisable by
means of the PCM600 ACT (Application Configuration Tool)
software, by means of which the user can create complex
logics according to the specific substation requirements.
The high degree of flexibility and configurability of the
protection and control unit makes the eVD4 circuit-breaker
very versatile and suitable for all types of use.

cation towards the switchgear.
