Gateway Function
The SCU 810 is designed for interconnection of the Iskra Sistemi’s control and protection IEDs, third- party IEDs and control centers:
• NEO 3000 IEDs (FPC 680, CAU 380)
• NEO 2000 IEDs (CAU 300 series, FPC 500 series, DAU 200 series)
• Any IEDs of different manufactures which support IEC 61850
• Any IEDs of third production by using internationally recognized communication protocols (see list on the last page)
• Station or dispatching control centers (NEO 3000 Control Center and others)
• Local SCADA MCE 940 for substation level control

Protocol converter function
SCU810 can also be used as protocol converter in smaller applications without external serial port multiplicator unit ECU 032. Beside smaller amount of serial interfaces and inability to host internal GPS clock it provides all functionalities of normal sized SCU810.

Remote configuration of IED
The SCU 810 offers the unique function of remote configuration and remote service access to IEDs. That enables service access to the settings of the device and fault recording from any point in the communication network that SCU 810 is connected to.
Using that function in larger scale permits utility company to establish Protection Management System (PMS) for integral control of numerical protection relays and other IEDs. The function is not limited by IED vendor as SCU 810 uses standard serial communication interfaces.

Other Functions
• Time synchronization (via protocol, GPS clock, DCF clock, NTP/SNTP)
• Collection and transmission of energy metering from IEDs
• Collection and transmission of condition of individual IEDs
• Collection and transmission of high resolution events (1 ms time resolution)
