The DeltaV system uses DIN rail-mounted interconnecting carriers and
components that are designed for installation in an enclosure. The P-series
carriers provide power and communication connections. The I/O subsystem and the
controllers are modular; they simply plug onto the carriers for installation.
DeltaV system equipment consists of:
-
I/O Interface Carrier and P-series Controller/Power Module
Carriers that mount horizontally on DIN rails. The number in the carrier
name (such as 4-wide I/O interface carrier) refers to the number of slots
available for connecting the equipment to the carrier.
-
LocalBus that consists of busses on the associated I/O interface
carriers and connecting cables. The LocalBus supplies power to the I/O
subsystem and provides communications connections between cards. System power
(12 VDC) can be shared along the length of the LocalBus. The length of the
LocalBus, including all cabling, cannot exceed 6.5 m (21.3 ft.).
-
DeltaV I/O subsystem that includes I/O terminal blocks and I/O
cards. Terminal blocks snap onto the I/O interface carrier to provide screw
terminations for field wiring. I/O cards snap over the I/O terminal block on
the carrier and convert field signals to a digital format for control and
communications. You can install the I/O terminal blocks and connect field
wiring before installing the other devices, thus reducing installation and
maintenance costs.
-
DeltaV P-series Controller that performs local control and
manages communication between the I/O subsystem and the Control Network. It
mounts in the P-series controller carrier along with the power modules. You can
add an additional controller for controller redundancy.
-
DeltaV Power Module for the P-series controller is supported.
-
DeltaV Workstations that provide graphical user interfaces to
help you configure your system, perform extensive diagnostic checks, operate
your process, and gather reporting and historical data. The DeltaV System
Identifier, shipped in your License Pack, is a connector that plugs into the
Universal Serial Bus (USB) on your ProfessionalPLUS workstation. It gives each
DeltaV system a unique identification that allows you to install or download
changes to the system. The system identifier is not required for the system to
continue running or to restart the system after it has been running.
-
Bulk power supplies supply power to the system or to field
devices. Power to the system is isolated from power to field devices.
