DeltaV™ CHARM I/O Cards (CIOC) mounted on a Migration Panel.

DeltaV CHARM I/O Baseplate Migration Panel.

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.

CHARM and Terminal Block.

Field power is provided through a redundant 24V DC bus to 

each CHARM, with up to 100 mA per CHARM. Higher current 

Discrete Channels can be powered through integrated power 

injection bus local to each CHARM Baseplate.

CIOC Migration Panel

The CHARM I/O card carrier is supposed to be mounted 

on a vertical DIN-rail and can communicate with up to 

eight CHARM Baseplates mounted vertically or on migration 

panels and connected to each other through extender cables. 

The bus terminators are attached to the last baseplate.

Baseplate Migration Panel

Each CHARMs Migration Baseplate Assembly is 

ordered pre-loaded with 24 terminal blocks that are 

ready to receive field wires from 2-, 3- , and 4-wire devices. 

Electronic Marshalling eliminates the need to scramble the 

field wiring or to partition the I/O to match signals to channel 

types of specific cards. Simply connect field signals in an orderly 

fashion as desired. Insert the appropriate CHARM into each 

terminal block to complete the field circuit and the signal 

is ready to be used by any, up to four controllers.

For each Migration CIOC installation you will need to 

determine the quantity and connector cable length as 

well as the appropriate quantity of top and/or bottom 

baseplate terminators.

The Migration CIOC assembly has a height of 6 EIA units 

(10.5 inches) and is designed to be mounted at the top 

of the migration cabinet and connected to the CHARM 

baseplate assemblies through the cables and cable extenders. 

It should be noted that the CIOC can be mounted on vertical 

DIN-rail anywhere in the cabinet (front, back, side, top, 

middle, bottom) and connected to the CHARM baseplate 

assembly the same way. NOTE: the CIOC cannot be mounted 

on a horizontal DIN-rail.

The Migration CHARM baseplate assembly has a height of 

3 EIA units (5.25 inches) which allows for each installation 

to determine the mounting location within each cabinet. 

The user can decide to reuse existing wire way / cable tray, 

mount each assembly adjacent to each other, or mount with 

spacing between each assembly. DeltaV CHARMs allow for 

installation flexibility by allowing each assembly to be mounted 

as needed to achieve the best result for each customer-specific 

termination installation.

Each CHARM acts as a circuit protection device and field wiring 

disconnects. Signals are current limited or fused to protect 

against wiring faults to ground. Each CHARM provides surge 

protection to meet industry standards in the area of EMC, and is 

designed to fail during overvoltage conditions due to incorrect 

field wiring. Signal faults are isolated to the single CHARM.

CHARMs can be partially ejected to a locked position that 

disconnects the field wiring from the system to perform field 

maintenance actions or to remove power to a field device. 

Activating the CHARM latch ejects the CHARM to the detent 

position. Closing the latch locks the CHARM in place and 

isolates the field wiring for field work.

The CIOC communicates over Ethernet with up to four 

controllers, allowing great flexibility and ease of system 

expansion. Additional controllers can be added to 

accommodate increased control scope and I/O can be 

reassigned without changing the physical wiring. This allows 

you the flexibility required in migrations where over time 

I/O has been landed on one controller only to be used in 

another because of space and or available I/O.
