Emerson Product Description DeltaV™ Electronic Marshalling for Migrations

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).

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.

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.

CHARMs can be added to any existing base plate position

and autosensed online. Additional CIOCs can be added online.
