D/3 DCS System Architecture

Unparalleled Flexibility and Reliability

Open Networks, Off-the-Shelf Servers, and Full Systemwide Redundancy

Powerful

No other system offers the raw horsepower of the D/3®, with the ability to handle over 50,000 I/O points, its best-in-class Process Control Module (PCM), scalable vector graphics, and comprehensive operator console software.

Scalable

D/3 can scale from 2 to 160 nodes, drive up to 256 operator consoles, and control processes incorporating up to 128 PCMs. A D/3 System can manage hundreds of simultaneous batches and product recipes with no performance degradation.

Flexible

D/3 Online Upgrade technology allows customers to upgrade to newer D/3 versions without stopping plant operations. Its Client/Server architecture allows the logical separation and organization of plant control system functions. Users can change control system strategies on-the-fly with intuitive configuration and management tools.

Reliable

Customers have trusted their processes to D/3 since 1982 because of its proven reliability. D/3’s powerful PCM performs critical functions typically relegated to the HMI layer on less robust systems, allowing control functions to continue even if the HMI layer is disabled.

Cost Effective

Each PCM can control numerous unit operations and run hundreds of SABL® programs simultaneously.  Thousands of I/O points from multiple vendors can be connected via a single Ethernet I/O module, and entire processes may be simulated within the PCM. These and other features of the D/3 reduce hardware, wiring, licensing, programming, startup, maintenance, and other costs.

OrionLX Connects “Islands of Automation”

OrionLX
The Orion connects legacy equipment, “islands of automation”, and ancillary systems such as electrical substations, wastewater plants, scales, chart recorders and load-out facilities into the D/3 using the standard Modbus/TCP interface.  Hundreds of protocols supported and custom protocols available.
