With the introduction of I/O on Demand, an unprecedented amount of field I/O adaptability, ease-of-integration and plant availability becomes possible. Costs and concerns around single points of failure, marshalled crosswiring, power and grounding of FOUNDATION fieldbus segments, and late project I/O and process design change orders can completely disappear. Regardless of I/O type – traditionally wired I/O, FOUNDATION fieldbus, Profibus DP, DeviceNet, AS-i bus, or even redundant wireless–you can add and begin using the information all natively and with far less engineering, design, and field work. You choose the I/O you need, we make it easy.
Making late project changes is now easier and less costly, because new field wiring can be added to cabinets at any time with no impact on the system architecture. DeltaV Electronic Marshalling lets you land field cabling wherever you want, regardless of signal type or control strategies. With Electronic Marshalling, each terminal block has a single channel characterization module, or CHARM, which allows field wiring of any signal type to be terminated anywhere.
Electricians can terminate the field wires on terminal strips in the same way they have in
the past, but the cross-wiring from the marshalling panel to I/O cards has been eliminated. This greatly simplifies control cabinet design, installation, and maintenance. Trouble–shooting installation issues can be done on a channel–by–channel basis, because problems are isolated to a single channel.
Traditional I/O is a modular subsystem that offers flexibility during installation. It's designed to be installed in the field near your devices. Modularity, protection keys, and plug–and–play capabilities make DeltaV traditional I/O a smart choice for your process control system–available in two designs–S–series and M-series. The S-series exterior hardware design delivers easier installation and improved robustness while still using the same field-proven electronics and operating system as the M–series hardware.
Installation is easy and no–value engineering is eliminated. The DeltaV system enables you to add system components including controllers, I/O cards, field devices and workstations while the system is powered and running. You can expand and upgrade your system on–the–fly with no downtime. Both the S–series and M–series hardware can coexist in the same DeltaV system with no trade–offs or incompatibilities. DeltaV control hardware is built rugged and flexible to mount almost anywhere–even in the most extreme field conditions.
The DeltaV system is the only system built from the ground up to unleash the advantages
of digital fieldbus to deliver the project and operational savings of a digital plant–easy! Fieldbus power conditioners are integrated in the H1 card. This eliminates difficult segment power design, installation, and troubleshooting–along with eliminating cabinets for external Ff segment power supplies.
The DeltaV system also supports Profibus DP and DeviceNet and AS–i bus. The DeltaV system provides native support for configuring busses with no need for 3rd party configuration tools. Ethernet I/O devices are easily connected through a virtual I/O module. And the DeltaV system lets you take advantage of the HART–based intelligent field device diagnostics.
Many plants are missing important measurements – typically where it is cost prohibitive to add wiring. Emerson’s Smart Wireless Instruments create self-organizing wireless networks based on the globally accepted WirelessHART (IEC 62591) standard – providing secure, robust, and reliable performance. The DeltaV Wireless I/O Card is auto-detected on the DeltaV network and WirelessHART devices are auto-sensed as they are added to the network. No site survey is needed, so instrumentation setup is fast, easy, and cost efficient. Devices automatically find the best communication paths with adaptive, self-monitoring and self-healing mesh routing to ensure 99.9% reliability.
