is identified and the appropriate CHARM
card is set up and Electronically Marshalled
through a hidden digital bus to ANY
controller in the system. Fully redundant
power and communications connection is
included, and autosensing each I/O channel
means that identification, configuration,
diagnostics and design changes are easily
carried out by the DCS.
The technology provides many benefits,
from the first design stages, to
commissioning, and through the lifetime of
processing oriented manufacture. As digital
or analogue I/O of any type can be bound
to specific controllers at any stage in the
project without manual rewiring, hardware
and design costs can be more predictable
from the outset. Design changes – adding
new I/O or changing I/O types - can be
catered for without intensive labour
and disruptive re-wiring costs. Projects
become easier to scale, safety is assured.
Configuration and diagnostics are taken
care of by a single integrated software
platform – Emerson’s DeltaV Explorer.
