Introduction
Emerson introduced Electronic Marshalling in DeltaV™ v11.
Electronic Marshalling provided a new level of control system
I/O performance with unprecedented exibility and ease of
use. It provides single-channel granularity, fully redundant
communications, and plug and play I/O.
Electronic Marshalling with Distributed CHARMs enables you
to install CHARMs even closer to eld devices and can eliminate
costly engineering and installation efforts. When eld devices
are wired directly to CHARMs in a junction box close to the
physical location of the eld devices, the need for loop sheets
disappears because the wire path is direct. The time and
effort required to perform instrument loop checks is greatly
reduced as many eld devices are automatically recognized in
DeltaV. Multicore cables are replaced with Ethernet cables that
communicate the various signal types back to the CHARM I/O
Cards (CIOC) or CHARMs Smart Logic Solvers (CSLS).
Inside view of 12 CHARM I/O Junction Box with CHARMs, it provides
for easy termination close to eld devices.
Benefits
Reduce total install cost: Distributed CHARMs reduces
wiring and cable tray cost and the labor associated with
pulling wires and installing cable trays. Installation and labor
associated with wire preparation, terminations, and labeling
of wires is also decreased. The need for traditional loop sheets
is lessened or eliminated. Ringing out wires from terminations
to eld devices is simplied since devices are terminated
directly to the CHARM I/O Block close to the eld devices –
there are no complicated wire paths to document. The time
and effort needed to perform instrument loop checks are
minimized since smart devices communicate directly with
the DeltaV system. Construction and EPC engineering cost
can also be decreased since eld construction requirements
are lessened.

Improve flexibility by combining I/O types:
Traditional junction boxes in the eld are typically dedicated
to one signal type. For example, 120V AC and 24V DC are
separated to reduce noise interference. Thermocouple
multicore cables and RTD multicore cables cannot include
any other signal types. Different signal types must be isolated
in additional separate traditional junction boxes and multicore
cables, laid in separate cable trays, which require addition
engineering and installation efforts. With Distributed CHARMs,
all types of devices can be wired to the same 12 CHARM
I/O Junction Box and the shielded Ethernet cable used to
communicate back to the CIOC/CSLS can be installed
alongside other instrument cables.
Support for Smart Commissioning: All the benets of
Smart Commissioning are applicable to Distributed CHARMs.
A description for each CHARM I/O Block can be added in DeltaV
software for proper identication. The ability to connect
devices directly to 12 CHARM I/O Junction Boxes drastically
reduces costs and can eliminates the need for traditional loop
diagrams. In DeltaV Explorer a user can generate a report for
each CIOC/CSLS showing the CHARM number, signal tag and
CHARM I/O Block description – allowing you to easily locate
devices after installation is complete.
Product Description
The Distributed CHARMs hardware includes:
The CHARM I/O Gateway connected to the CIOC or
CSLS carrier or to a CHARM baseplate under the CIOC
or CSLS carrier.
The CHARM I/O Block that includes 12 CHARM slots and
can be installed close to the eld devices.
The IS CHARM I/O Block that includes 12 IS CHARM slots
and can be installed close to the eld devices.
The CHARM I/O Gateway and both the CHARM I/O Block and
IS CHARM I/O Block have Scanner Modules and Ethernet I/O
Ports (IOP) that facilitate communication between the CIOC
or CSLS and each CHARM over full duplex 100BASE-TX Ethernet.
These products support star or a fault tolerant ring topology
using copper Ethernet.
Works with both DeltaV and DeltaV SIS: Distributed CHARMs
can be used with both DeltaV and DeltaV SIS. The CHARM I/O
Gateway can be installed either under a CIOC or a CSLS carrier
and the CHARM I/O Block can hold either regular CHARMs or
Logic Solver CHARMs. The Distributed CHARMs hardware is
deemed non-interfering during SIS certication.
Works for both regular and IS CHARMs: There are two types
of CHARM I/O Block Carriers available, one for regular CHARMs
and another one for IS CHARMs.
Reduce number of CIOCs and CSLSs: Installations with an
average number of CHARMs per CIOC or CSLS have room
to install more CHARMs. With the Distributed CHARMs
architecture, the average number of CHARMs per CIOC
and CSLS can increase and the number of CIOCs, CSLSs and
SZ controllers with associated networking equipment for the
Local Safety Network (LSN) can be reduced.
Improve CIOC/CSLS utilization through expansions:
An existing CHARM I/O Field Enclosure that has unused CHARM
Baseplates can easily be expanded by installing the CHARM
I/O Gateway in available enclosure space. New 12 CHARM I/O
Junction Boxes can be installed near the expansion area.
This takes advantage of available capacity and eliminates
the need for additional CHARM I/O Field Enclosures.

CHARM I/O Gateway
The CHARM I/O Gateway consists of the following parts:
CHARM I/O Gateway Carrier holds the CHARM I/O Scanner
Module(s) and IOP(s), and potentially protection cover(s)
in simplex congurations.
CHARM I/O Scanner Module can be installed as simplex
or redundant on the CHARM I/O Gateway Carrier. DeltaV SIS
installations require redundancy to ensure availability.
CHARM I/O Gateway 8-port IOP can be installed as simplex
or redundant on the CHARM I/O Gateway Carrier and is
used for star Ethernet topology. When used with DeltaV SIS,
redundancy is required to ensure availability.
CHARM I/O Gateway 1-port IOP is used for fault tolerant
ring Ethernet topology and requires 2 IOPs installed on the
CHARM I/O Gateway Carrier.
CHARM I/O Scanner Module Protection Cover is used in
simplex Scanner Module conguration and is mounted
in the unused scanner module slot on the CHARM I/O
Gateway Carrier.

Electronic Marshalling.
The star Ethernet topology is supported with both
simplex and redundant Ethernet communication.
Redundant communication provides high availability and
requires two 8-port IOPs while simplex only requires one
IOP and one IOP protection cover. The star topology allows
maximum 100m distance between the CHARM I/O Gateway
and each CHARM I/O Block or IS CHARM I/O Block. DeltaV
Media Converters
can be used to extend beyond 100m. Redundancy is required
if Star topology is used in SIS installations.
Fault tolerant ring topology enables you to install CHARM I/O
Blocks further away from the CIOC or CSLS by daisy-chaining
them together. The 100m maximum distance in ring topology
is between the CHARM I/O Gateway and the rst CHARM I/O
Block, but 100m is also allowed between each CHARM I/O Block
on the ring and between the last CHARM I/O Block and back to
the CHARM I/O Gateway. DeltaV Media Converters can be used
to extend beyond 100m. The ring topology reduces Ethernet
wiring as compared to star topology especially if compared to
redundant star topology.
CHARM I/O Gateway IOP Protection Cover is used in a simplex
star Ethernet topology and is installed in the unused IOP slot
on the CHARM I/O Gateway Carrier.

The CHARM I/O Gateway is installed on the rail under the
CIOC or CSLS carrier. Regular CHARM Baseplates can be
installed both above and below the gateway and regular
Cable Extenders can be used as well. A CHARM Baseplate
Terminator is still required after the last CHARM Baseplate or
after the CHARM I/O Gateway if there is no CHARM Baseplate
after it. Any IS CHARM Baseplates must be mounted below
the gateway.
The Scanner Modules communicate with the CIOC or CSLS
through the backplane and communicates to the CHARM I/O
Blocks and IS CHARM I/O Blocks through the IOPs. The CHARM
I/O Gateway is powered by the redundant 24V DC power
supplied to the CIOC or CSLS carrier.
CHARM I/O Block
The CHARM I/O Block consists of the following parts:
CHARM I/O Block Carrier holds the CHARM I/O Scanner
Module(s), IOP(s), and potentially protection cover(s) in
simplex congurations. It supports up to 12 CHARMs and
their terminal blocks, as well as an Address Plug with
terminal block.
CHARM I/O Scanner Module is installed as simplex or
redundant on the CHARM I/O Block Carrier. The CHARM I/O
Scanner Module is the same for both the CHARM I/O Gateway
and the CHARM I/O Block. When used with DeltaV SIS,
redundancy is required.
CHARM I/O Block IOP can be installed either as simplex or
redundant on the CHARM I/O Block Carrier and is used for
both star and ring topology. In a simplex conguration the
IOP must be installed in the same position as the 8-Port IOP
in the CHARM I/O Gateway. For example, if the gateway has
an 8-port IOP installed in port A, then any CHARM I/O Block
connected must also have the IOP installed in port A. If a ring
topology is used, both IOPs must be installed. When used
with DeltaV SIS, redundancy is required.

CHARM I/O Block with redundant Scanner Modules and IOPs,
a combination of CHARMs and Channel Identier
Label/Wiring Cover.
The CHARM I/O Block is mounted in the eld close to the
eld devices and supports all non-IS CHARMs and LS CHARMs.
The CHARM I/O Block does not support IS or LS IS CHARMs.
The CHARM I/O Block supports redundant power and has
terminals for two separate 24V DC power inputs. It also
has twelve shield return terminals, one for each CHARM,
similar to those on a regular CHARM Baseplate. There are
also two terminals to ground the shield returns.
Each CIOC is still limited to a maximum of 96 CHARMs and
eight CHARM Baseplates. Each baseplate must have a unique
address plug, 1 through 8, and the eight baseplates can be
a mix of local CHARM Baseplates under the CIOC or CSLS and
distributed CHARM I/O Blocks installed close to the
eld devices.
CHARM Terminal Blocks or LS CHARM Terminal Blocks.
Up to 12 terminal blocks are supported. The IS CHARM
Terminal Blocks are not supported on the CHARM I/O Block.
Address Plug Terminal Block with Address Plug provides
addressing for the CHARM I/O Blocks.
CHARMs or LS CHARMs. Up to 12 CHARMs are supported.
IS or LS IS CHARMs are not supported on the
CHARM I/O Block.

IS CHARM I/O Block
The IS CHARM I/O Block consists of the following parts:
IS CHARM I/O Block Carrier holds the CHARM I/O Scanner
Module(s), IOP(s), and potentially protection cover(s) in
simplex congurations. It supports up to 12 IS CHARMs
and their IS terminal blocks, as well as an Address Plug
with IS terminal block.
CHARM I/O Scanner Module is installed as simplex or
redundant on the IS CHARM I/O Block Carrier. The CHARM I/O
Scanner Module is the same for both the CHARM I/O Gateway
and the IS CHARM I/O Block. When used with DeltaV SIS,
redundancy is required.
CHARM I/O Block IOP can be installed either as simplex or
redundant on the IS CHARM I/O Block Carrier and is used for
both star and ring topology. In a simplex conguration the
IOP must be installed in the same position as the 8-Port IOP
in the CHARM I/O Gateway. For example, if the gateway has
an 8-port IOP installed in port A, then any CHARM I/O Block
connected must also have the IOP installed in port A. If a ring
topology is used, both IOPs must be installed. When used
with DeltaV SIS, redundancy is required.
IS CHARM Terminal Blocks. Up to 12 IS CHARM terminal
blocks are supported.
Address Plug Terminal Block for IS with Address Plug
provides addressing for the IS CHARM I/O Blocks.
IS CHARMs or LS IS CHARMs. Up to 12 IS CHARMs
are supported.
Horizontal Channel Identier Labels for IS CHARM I/O
Block for protecting terminations and holding a label
for channel identication.
