EMERSONDeltaV™ Electronic Marshalling for Migrations

„ CHARM Baseplate (DIN-rail mounted with interleaving power 

and bus connectors. Supports 12 CHARMs and their terminal 

blocks, as well as connection for injected field power).

„ CHARM Terminal Block (removable terminal block 

providing terminal connections to field wiring and 

physical latch for CHARM).

„ CHARMs (Characterization Module for each field signal. 

Provides basic analog to digital conversion, connectivity 

to redundant communication bus, and fault isolation)

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.

Product Description

Electronic Marshalling for Migrations hardware includes:

„ CHARM I/O Carrier (DIN-rail mounted and supports 

redundant pair of CHARM I/O Cards).

„ CHARM I/O Card (CIOC) provides communication between 

CHARMs and the Ethernet I/O network to M-series, S-series, 

and PK controllers. The CIOC has Achilles Communications 

Certification Level 1 and the redesigned CIOC2 has more 

computing power and Achilles Communications Certification 

Level 2. The CIOC2 is a drop-in replacement for the CIOC.

„ CHARM Baseplate (DIN-rail mounted with interleaving power 

and bus connectors. Supports 12 CHARMs and their terminal 

blocks, as well as connection for injected field power).

„ CHARM Terminal Block (removable terminal block 

providing terminal connections to field wiring and 

physical latch for CHARM).

„ CHARMs (Characterization Module for each field signal. 

Provides basic analog to digital conversion, connectivity 

to redundant communication bus, and fault isolation)

„ Cable Extenders that provide flexibility in carrier mounting.

„ Baseplate terminators (provides bus terminations for 

redundant I/O bus).

„ 19” Migration Panels (provides DIN-rail mounting for two 

migration CIOC’s or two baseplates and cable extenders 

for installation into your standard 19” legacy cabinets).

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
