5.5.10.1 Functions
Communication between one central station and one or several substations according to
DNP3 via Ethernet (TCP/IP).
• Unbalanced multi-point traffic according DNP3
DNPiT1 is substation
─ Data acquisition by polling (station interrogation)
─ Acquisition of events (transmission of data ready to be sent, unsolicited responses)
─ General interrogation, outstation interrogation
─ Command transmission
─ Transmission of integrated totals
DNPiT2 is central station
─ Data acquisition by polling (station interrogation, event interrogation)
─ General interrogation, outstation interrogation
─ Command transmission
• Max. connections (number of supported DNP Slaves): 4
• Physical interface
─ LAN (TCP/IP)
• Supported functionality according to the following document:
─ SICAM RTUs DNP3 Interoperability, chapter "Interoperability of SICAM RTUs for
DNP3 Slave (serial + Ethernet) using DNPS" (DC0-046-2)
• Clock synchronization according to NTP (Network Time Protocol) - RFC 1305
─ NTP Client: Clock synchronization with one or more NTP servers
─ NTP Server: integrated NTP server for clock synchronization of one or several NTP
clients
• Functions for supporting redundant communication routes
• SICAM TOOLBOX II connection over LAN/WAN ("remote operation")
─ connection via proprietary TCP/IP protocol (one SICAM TOOLBOX II session can be
served at the same time)
• Web server
─ Integrated web server to display connection-/statistic-/developer information
─ Access to the web server with standard web browser via HTTP (Hyper Text Transfer
Protocol)
• Special functions
