The Network Manager™ data acquisition function manages communication with RTUs, IEDs and substation automation devices in supervisory control systems. It provides flexibility, performance and scalability in a cost-effective solution.

The data collection system supports international communication protocols and multiple RTU types. It further supports a variety of communication structures e.g. redundant lines.

Data Acquisition Features:

• Handles multiple protocols, one protocol per line
• Periodic scanning of RTUs and scan groups; different scan rates for cyclic protocols
• Reduces SCADA server I/O overhead; large amounts of data in a single block
• Connected to server via LAN or WAN, by TCP/IP protocol; capable of dual LAN connection
• Performs dead-band based report-by-exception of data when sent to the server.
• Converts protocol-dependent RTU replies to a protocol independent format, which isolates the server from protocol specifics
• Downloads point/RTU/scan group database from the server at start-up
