SCADA RTU (and PLC) interface

• All compatible protocols included as standard
• DDE drivers supported
• Interface also possible for RTUs, loop controllers, bar code readers and other equipment
• Driver toolkit available
• Operates on a demand basis instead of the conventional predefined scan method
• Optimization of block data requests to PLCs
• Rationalization of network user data requests
• Maximization of PLC highway bandwidth

SCADA Scalability

• Additional hardware can be added without replacing or modifying existing equipment
• Limited only by the PLC architecture (typically 300 to 40 000 points)

SCADA Access to data

• Direct, real-time access to data by any network user
• Third-party access to real-time data, e.g. Lotus 123 and Excel
• Network DDE
• DDE compatibility: read, write and exec
• DDE to all IO device points
• Clipboard

SCADA Database

• ODBC driver support
• Direct SQL commands or high level reporting

SCADA Networking

• Supports all NetBIOS compatible networks such as NetWare, LAN Manager, Windows for Workgroups, Windows NT (changed from existing)
• Support protocols NetBEUI, IPX/SPX, TCP/IP and more
• Centralized alarm, trend and report processing – data available from anywhere in the network
• Dual networks for full LAN redundancy
• No network configuration required (transparent)
• May be enabled via single check box, no configuration
• LAN licensing is based on the number of users logged onto the network, not the number of nodes on the network
• No file server required
• Multi-user system, full communication between operators
• RAS and WAN supported with high performance
• PSTN dial up support

SCADA Fault tolerance and redundancy

• Dual networks for full LAN redundancy

• No configuration required, may be enabled via single check box, no configuration

SCADA Client/server distributed processing

• Open architecture design
• Real-time multitasking
• Client/server fully supported with no user configuration
• Distributed project updates (changes reflected across network)

• Concurrent support of multiple display nodes
• Access any tag from any node
• Access any data (trend, alarm, report) from any node
