Substation central unit - Communications front-end. - IED communication management. - Automation and programmable logic modules. - Management of communications with higher levels (Scada). - Management of local and remote communications with HMI. - Real time database generation of all substation variables. - Communications ports: · One (1) local communications port (RS232). · Remote ports (serial): PR1: RS232 (Scada). PR2: RS232 (Scada). PR3: RS232 (connection to remote HMI or protocol emulation). PR4: RS232 (connection to IEDs no PROCOME). · Remote ports (F.O): PR1 - PR6: F.O. (IED connection). PR7 - PR12: F.O. (IED connection) (optional). - Automation and logic operations. - Event, metering and counters history record. - Redundancy:: · Redundant network operation (Double Star and Double Ring). · Operation with a second spare UCS in double or "Hot-Stand-By" mode. - Integrated signal, metering, counter and command simulator. - WAN communications through telephone network (switched, leased, or GPRS) via external modem and through corporate Ethernet: · Dial up service for connection to remote access server (RAS) through standard PPP protocol. · Remote access server (RAS) through PPP protocol accepting incoming remote connections. · Routing operation within shared LAN of substation IEDs, allowing remote connection to IEDs via the Substation Central Unit. - Servers: Web, FTP, files, printing, TELNET. - SNP protocol Client / Server service. - User management and login passwords for every service provided by the Substation Central Unit. through SSPL authentication services. - Communications protocols: · Modules with asynchronous serial protocols for relay communications (Level 1) PROCOME, DNP 3.0, IEC 870-5-10, SPABUS, MODBUS, etc. · Modules with asynchronous serial protocols for Telecontrol communications (Level 3) IEC 870-5-101, 104, DNP 3.0, GESTEL, PID1, INDACTIC 2033, SEVCO 6802, WISP, etc. · Server modules for HMI communications. Local and remote connection via protocol through TCP/IP (Ethernet or asynchronous serial channel). |
