EMERSONDeltaVTM Digital Automation System

ughout the Architecture

Time-stamped and validated at the source Digital automation systems, like the DeltaV system, are built to receive, store and use data timestamped in digital field devices (where supported). With the addition of a GPS time server, these time stamps are within 1msec. Health of the information comes from status data sent by field devices and propagated throughout the DeltaV system. For your traditional field devices, the DeltaV system offers digital Sequence of Events (SOE) interfaces that provide time stamping in the SOE cards to 1msec resolution

User security Built on Windows workstation security, the DeltaV system provides easy, flexible, system-wide security management for all users including operators, engineers, technicians, and other automation users. Based on user login, these keys control both system functionality and span of operator control. Security settings include: „ Operating span of control by plant area „ Alarm limits, tuning parameters change privilege „ Security by both user and by physical location.

The DeltaV control hardware delivers big savings in the installation process. The compact, modular design allows you to cost-effectively meet your process needs. Easy, flexible installation Installation is easy since I/O is automatically auto-sensed when added to the system. No-value engineering is eliminated. DeltaV control hardware is built rugged and flexible to mount almost anywhere. It’s built for: „ Class 1, Division 2 areas „ CENELEC Zone 1/2 areas „ ISA-S71.04-1985 Airborne Contaminants Class G3. Shared Zone 1 Remote I/O Additionally, shared remote I/O is available for Zone 1 and Zone 2 installations. Unlike other remote I/O, shared remote I/O can be shared among several controllers for a greater range of applications and installation flexibility. The DeltaV control hardware has many mounting options available to reduce your installation costs. Some options include: „ DIN-rail field junction box „ High-density cabinet mount „ DIN-rail wall mount „ Skid mount. Hot swappable Unlike other automation solutions, the DeltaV system lets you add system components including controllers, I/O, field devices and workstations while the system is powered and running. You can expand and upgrade your system on the fly with no downtime. Classic field interfaces The DeltaV system also supports a full range of analog, discrete, thermocouple, and RTDs for your existing field devices. Intrinsically safe The DeltaV intrinsically safe field interface subsystem connects intrinsically safe field circuits and field devices into Class 1, Division 1, Zone 1, and Zone 0 hazardous areas for most standard analog input, analog output, discrete input, and discrete output applications. Field power injection Unlike most existing automation systems, the DeltaV system injects field power right at the field interface terminations, significantly reducing installation cost by: „ Eliminating marshalling wiring „ Reducing cabinet or junction box footprint „ Reducing labor for additional terminations
