Emerson DeltaV™ Electronic Marshalling for Migrations Benefits

Benefits

I/O anywhere you need it: The DeltaV CIOC provides

unprecedented flexibility in control system I/O topology.

Now you can mount your DeltaV I/O in the same space as your

legacy I/O for a direct 1-to-1 replacement. Without adding

any new cabinets of DeltaV hardware you can replace all your

legacy equipment leaving behind a complete DeltaV solution.

Single Channel granularity: The CHARM I/O architecture

allows each individual channel to be characterized for the

requirements of the field device. Any instrument signal can be

wired to any terminal block. The channel is then electronically

marshalled by installing the appropriate CHARM and assigning

the channel to one of four controllers. Legacy I/O terminations

are no longer a concern because of multiple channel types

from a single termination panel. Just install the proper CHARM

to characterize the I/O as found on the legacy panels. No more

engineering and splitting signals from a single legacy panel to

multiple DeltaV I/O cards

Replaces legacy I/O in place: DeltaV Electronic Marshalling

goes where no one else’s I/O can. Install the CHARMs migration

panel above, below, or even in front of your legacy termination

panel and move your wires inches to complete your migration

to DeltaV. Since the CHARMs migration panel is a standard

CHARMs baseplate, it talks to the CIOC the same as the

standard vertical installation through the cable interface.

This allows you to mount the migration panel in the best

location to facilitate a clean system cutover and not have to

“stretch” your I/O cables to a new termination. As an added

bonus, install CHARMs vertical if your wiring allows for it in

certain areas. Now you can mount your I/O in any orientation

as best fits your current migration layout and needs.

Fully redundant communications: The CIOC architecture is

fully redundant. This starts with the two I/O cards on a carrier.

The carrier has redundant communication modules for primary

and secondary network connections. There are two 24 V DC

input power connections. The carrier connects to the CHARMs

Baseplates and provides redundant power and communication

buses to the CHARMs. Everything is redundant down to the

individual channel.
