1 Introduction
1.1 Application
The PRS-7910 Station Manager is designed for the highest standards of performance, safety and
reliability to meet requirements of a complex substation automation system (SAS). As a part of the
SAS, it works as a station communication manager, which collects, stores and maps signals of
relays, measurement units, control units and other IEDs in the substation to higher-level systems
such as control center (CC) and distributed control system (DCS).
The PRS-7910 supports several protocols, such as IEC 61850, IEC 60870-5-101/104, IEC
60870-5-103, Modbus and DNP3.0. Data can be transmitted to and received from analog channel,
digital channel or network connected to CC, DCS or other system. The direct transmission mode
and the device independent avoid any interaction or influence with the substation SCADA
(Supervisory Control And Data Acquisition) system.
Furthermore, the PRS-7910 can runs as a data acquisition and logic treatment platform and
provides various and flexible advanced function extensions.
NOTICE!
An additional protocol requirement besides the standard package can be customized,
please declares the protocol requirement clearly in the technical agreement and the
contract.
