Introduction

DeltaV™ Electronic Marshalling delivers a new level of control

system I/O performance with unprecedented flexibility and

ease of use. The CHARM I/O card (CIOC) supports up to

96 individually configurable channels and when mounted

horizontally in conjunction with a legacy system migration

will allow for direct replacement of legacy hardware within

existing cabinets. Now you can migrate to DeltaV without

having to add cabinets, custom cables, or extra marshalling.

All communications are completely redundant from the

channel (CHARM) to the DeltaV controller.

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.

Complete DeltaV solution: Migrate from your legacy system

with the comfort that when complete you will have a complete

DeltaV solution, not a combination of standard and custom

hardware/software to support. Every piece of the migration

panel is standard DeltaV hardware and can be supported with

the same personnel and spare equipment that every other

CHARMs and DeltaV installation uses.

Plug and play I/O: The DeltaV CIOC has been designed for

ease of use, both in physical installation and its software tools.

Components snap together with secure DIN-rail latches and

interlocking carrier connectors. Insert the CHARMs and auto

sense the node to create the I/O definition automatically in

your DeltaV configuration database. CHARMs use a self-keying

system to automatically set a channel for a specific CHARM

type. Users cannot mistakenly insert a CHARM into the wrong

terminal block. Assign all, one, or any number of channels to a

controller with a simple click and drag.
