GE INFORMATION
CHAPTER 1: BEFORE YOU START
Description
Capable of communicating with one or more
master stations using the MODBUS protocol
(RTU & ASCII modes).
A sub-master within a SCADA system,
controlling SEL relay equipment using SEL's
ASCII character-based relay protocol
Convenient and flexible soft logic utility that
can perform applications such as substation
level interlocking, feeder interlocking, and
converting digital inputs to control outputs for
driving a map board
Allows status and analog input values to be
suppressed for maintenance purposes.
Communicate with one or more hosts using the
IEC 60870-5-101/104 (T101) protocol. Has the
ability to function as several distinct IEC 60870-
5-101/104 RTUs. Supports the unbalanced
version of the data link.
Provides DI points each representing a group
alarm. The group alarm is generated when the
number of DI points in the alarm state exceed
the group threshold value.
Programmable Synchrocheck Relay (PSR) DCA
acts as a data concentrator for several remote
PSRs. The DCA and remote PSRs function as a
remote synchronous closure controller.
Allows configurable combination of control
requests to result in a failover or switchover of
a redundant system.
Provides AI points each derived from an
Automatic Selection Method (ASM). An ASM
selects the highest priority valid frequency
measurement from a group of AI points.
Generates control lockout indications, digital
input suppression or unsupression indications,
and control active indications.
Provides an interface to Sub-Remote Units
(SRUs) using the MODBUS protocol over the
TCP/IP communication layer.
Provides communications with one or more
master station using the MODBUS protocol
over TCP/IP communication layer.
Translates control requests into conventional
trip/close operations in conjunction with
secondary control operations to be used as a
Secondary Master Trip or Close.
Takes several alarms and groups them
together under one General Alarm.
Emulates the Landis & Gyr 8979 RTU.
Communicates with multiple master stations,
over redundant communication lines.
Calculates power from monitored voltage,
current, and phase angle. Also, performs time
integrated analog averaging, relative to the top
of the hour.
Performs time integrated analog averaging,
relative to the top of the hour.
Monitors and controls Cooper devices using
the Cooper 2179 protocol.
Provides I/O point redundancy.
