R E R6 20
A DVA N C ED R EC LOSER P R OT EC T I O N & CO N T R O L
lay has been provided with a four-level, role-based
user authentication system, with individual pass-
words for the viewer, operator, engineer, and ad-
ministrator levels. The access control system ap-
plies to the front panel HMI, embedded web
browser based HMI, and the PCM600 relay setting
and configuration tool. RER620 supports the new
IEC 61850 standard for inter-device communication
in substations or along the feeder. The relay also
supports the industry standard DNP3 level 2, Mod-
bus, IEC 60870-5-101/104 and PG&E 2179 protocols.
2. Standard configurations
The RER620 relay’s main application is feeder pro-
tection and control and offers one standard config-
uration whose relay functions and features are
based on the ordering code. See Tables 1 for de-
tails. The standard signal configuration can be al-
tered by means of the graphical signal matrix or the
optional graphical application functionality of the
Protection and Control protection and control relay
Manager PCM600. Further, the application configu-
ration functionality of PCM600 supports the cre-
ation of multi-layer logic functions utilizing various
logical elements including timers and flip-flops. By
combining protection functions with logic function
blocks, the protection and control relay configura-
tion can be adapted to user specific application re-
quirements.
Configuration includes standard metering, moni-
toring and control features and sequence of event,
fault and digital waveform recording. Advanced
Ethernet communications included standard with
parallel support of DNP3.0 Level 2+*, IEC 60870-5-
104, Modbus and IEC61850 and SNTP over TCP/IP.
Additional RS-232 and RS-485 serial communica-
tion ports are available as options that support
DNP3 Level 2+*, IEC 60870-5-101, Modbus or PG&E
2179 protocols. Included with the optional serial
communication ports is IRIG-B time synchroniza-
tion.
*The DNP3.0 PG&E 2179 Level 2+ implementation in-
cludes some Level 3 functionality.
