Features
- Eliminate marshalling and add I/O anywhere in the plant without affecting control room cabinets
- No marshalling cabinet or cross-wiring, fewer wires, much less work and fewer contact points for potential failures
- No marshalling cabinet or cross-wiring, fewer wires, much less work and fewer contact points for potential failures
Easily apply security using DeltaV built-in security features
The DeltaV control network architecture creates a separate control system network completely segmented from other networks in the plant, delivering a system inherently protected from unauthorized external access.
Reduce implementation effort with no-hassle security solutions
DeltaV Smart Switches provide auto port lockdown to prevent unauthorized access to the network from switch ports.
Monitor and manage network devices within the DeltaV system
All routine system maintenance and troubleshooting is done from secured DeltaV workstations so physical access to equipment is not required.
Improve system availability and reduce troubleshooting efforts
All network equipment supplied with the DeltaV system is fully tested and supported by Emerson as part of DeltaV development.
Easily integrate data The DeltaV DCS simplifies data integration …
• At the device level: Plug-and-play capabilities exist for runtime and diagnostics in a variety of standard protocols.
• To enterprise business systems: Connect via industry standard OPC along with built-in Service-Oriented Architecture (SOA) web services that provide connections to Emerson’s Manufacturing Execution System, Syncade™, and other systems.
• Between the field and business systems: Connections are made with minimal setup time. Decision makers at every level in the plant can get the critical data they need, reliably, securely, and in real time.
