PRS-7910 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.
