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

is designed specifically for multi-core home run cables

in centrally located marshalling cabinets. It can also be

installed in field junction boxes to further reduce system

design and installation costs. All communications are

completely redundant from the channel (CHARM) to the

DeltaV controller.

Benefits

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

unprecedented flexibility in control system I/O topology.

Using standard Ethernet infrastructure hardware you can

add I/O anywhere you need it. From a local I/O cabinet to

remote enclosures miles away, simply install the hardware

and connect it to the DeltaV control network. Each I/O card

can serve I/O signals to any four controllers in the system

with 50-ms updates for fast, reliable control.

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. Home run multi-core instrument cables can

be landed in order on a series of CHARM terminal blocks

without concern for signal types.

Reduces installed cost of system: DeltaV Electronic

Marshalling helps reduce overall system costs by

eliminating internal cabinet cross wiring, reducing overall

footprint, simplifying I/O channel assignments, and

reducing Factory Authorized Testing activities. Electronic

Marshalling provides separation between I&E hardware

installation schedules and control strategy development.

Wiring can begin earlier knowing any late changes

can be done without lifting a wire. Separation of the

controller and I/O allows more efficient cabinet designs

and accommodates late scope changes you can add I/O

anywhere. Adding additional control capacity does not

require re-wiring I/O. Simply assign the control modules

and their I/O signals to the new controller, without lifting

a wire.

 

Product Description

Electronic Marshalling hardware includes:

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

redundant pair of CHARM I/O Cards, redundant 24

V DC power connectivity, and redundant Ethernet

communication modules).

„ 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 (v13.3.1 or later

is required).

„ CHARM Base plate (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 and signal

isolation to the redundant communication bus).

„ Cable Extenders that provide flexibility in

carrier mounting.

„ I/O bus termination (provides bus terminations for

redundant I/O bus).

„ Labeling features for baseplate and channel identification.

 

CHARM Types

A variety of analog and discrete CHARMs are available to

meet your specific requirements. The following CHARMs are

available starting with v11.3.1:

„ AI 4-20 mA HART

„ RTD

„ Thermocouple / mV

„ AI 0-10V DC Isolated

„ AO 4-20 mA HART

„ DI NAMUR

„ DI 24V DC low-side sense (dry contact)

„ DI 24V DC Isolated

„ DO 24V DC High Side

„ DO 100mA Energy Limited

„ DO 24V DC Isolated

„ 24V DC Power

„ DI 120V AC Isolated

„ DI 120V AC Isolated Plus

„ DI 230V AC Isolated

„ DO V AC Isolated

All CHARMs have a bi-color power/integrity LED that

indicates the health of the CHARM. The indications provide

clear, actionable instruction to the maintenance personnel.

„ Green Solid: Normal Operation

„ Green Blink: Normal awaiting configuration

„ Red Blink: Fault detected on wiring

„ Red Solid: Internal Fault detected

Discrete CHARMs have a yellow LED to indicate the state of

the field signal. (On = circuit is energized)

All CHARMs meet ISA 71.04-1985 severity level G3 (harsh)

corrosion specifications.

24V DC based discrete input CHARMs support pulse

counters with a maximum frequency of 10 KHz.

I/O Terminal Block Options

„ There are six different I/O terminal blocks available to

meet the wiring needs of field signals

„ Standard Terminal Block

„ Fused-Injected-Power Terminal Block

„ 3-wire DI Fused Injected-Power Terminal Block

„ Relay Output Terminal Block

„ Thermocouple / mV Terminal Block

„ 3-wire AI Fused Injected Power Terminal Block

The Standard Terminal block can be used with all CHARM

types. For traditional wiring of field instrumentation,

the CHARMs provide loop power through the internally

distributed 24V DC field power. Refer to specific CHARM

specifications for wiring information.

The Fused-Injected-Power Terminal block, the 3-wire

DI Fused-Injected-Power Terminal block, and the 3-wire

AI Fused Injected Terminal block includes a 2A field

replaceable fuse. The 3-wire DI Fused-Injected-Power

Terminal block is designed to be used with all isolated

discrete Input CHARM types, while the Fused Injected

Power Terminal block is designed to work with all Isolated

discrete Output CHARM types, the 3-wire AI Fused

Injected Power Terminal block is used with AI 4-20mA

HART CHARM type creating a system-powered circuit that

can deliver up to 1 amp (DC) to the field.

Each baseplate has a local power bus that can be

connected to 24V DC or 120/230V AC through the injected

power input terminals, located on the Address Plug

terminal block. Both, the fused-injected power Terminal

Block, the 3-wire DI fused- injected power Terminal Block,

and the 3-wire AI Fused Injected Terminal block connect to

this power bus to provide system power to the field circuit

through the isolated CHARM. You can combine isolated and

system powered circuits on the same baseplate, however, all

system powered channels on a baseplate share the same

power source.
