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.

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

Some of the events that can cause a switchover are:

•Hardware failure within the active controller

•Communications failure between the active controller and I/O

•Communications failure on both control network ports of the

active controller

•Removal of the active controller from the carrier

•User request initiated from Diagnostic Explorer

System Compatibility

M-series, S-series and SZ controllers are all supported on

DeltaV v12.3 and beyond. PK Controllers are supported on

DeltaV v14.3 and beyond. For detailed version compatibility

see the Prerequisites section below.

Redundant controller pairs must be of the same series. For

example, M-series and S-series controllers cannot be connected

together as a redundant pair.

Although an SX controller can operate as a standby controller to an

SQ active controller, it is recommended that both the active and

standby controllers be of the same hardware. The SQ may not have

sufficient memory or CPU capacity to accept the configuration that

runs in an SX controller. This applies for MX and MQ controllers as

well, only mix controller types as a temporary condition during a

hardware upgrade.

The MQ, MX, SQ, SX and PK Controllers are all capable of

redundancy. For more information on these controllers, refer to

the respective controller product data sheet.

SZ Controllers are also capable of redundancy. For more

information on this controller, refer to the DeltaV SIS Electronic

Marshalling or DeltaV SIS IS Electronic Marshalling product data sheets.

Automatic commissioning. The system automatically detects,

commissions, and downloads a standby controller so you can

safely replace a unit in the field. Redundancy can be added

online by simply installing a new 2-wide backplane with a

system power supply and MQ, MX, SQ, or SX controller on it.

The SZ controller carrier, or the Dual Universal Safety Carrier,

provides 2 slots for SZ controllers, so there is nothing to add

other than the additional SZ controller. The PK controller carrier

also provides 2 slots, so simply add an additional PK controller

to the existing carrier. The engineering database is updated

automatically, simply assign and download the controller

redundancy license to activate the standby controller, all with

no impact to your running process.

There are no dip-switches, jumpers or addresses to assign. The

standby controller is automatically assigned the appropriate

standby address and begins working, protecting your process.

Bumpless transition. DeltaV controllers are designed for a

bumpless transfer of control from the active controller to the

standby controller. During this time, output channels hold

their output states until the switchover is complete and control

modules begin executing. The control module uses signal status

to ensure all I/O channels are good before taking control action

on them, and all output signals are synchronized through I/O

readback features to ensure control calculations are based on

current output states.

Benefits

Uninterrupted control operation. By installing redundant

M-Series, S-Series and PK controllers, you can establish a

“safety net” to protect your process from unexpected controller

failures. The standby controller stands ready to maintain control

and process uptime in the face of hardware failures.

Online Upgrades. Installing redundant DeltaV controllers

enables you to perform online upgrades to your DeltaV system.

New firmware can be installed in the standby controller while

online without affecting operation. Once upgraded, the

standby is automatically configured and becomes available,

allowing a switchover to the new firmware without disrupting

the process. Once the switchover is complete, the original

active controller can then be upgraded. In addition, an MQ

controller can be upgraded online to an MX controller, and an

SQ controller can be upgraded online to an SX controller. This

ensures your system is always ready to expand as your control

strategy grows.

This ensures a bumpless transfer of control during the

switchover when using CHARM or DeltaV Classic I/O cards, with

or without Foundation™ fieldbus devices.

Field Proven Architecture.

The S-Series controllers are an evolution of DeltaV M-Series hardware.

The new design delivers installation and robustness enhancement while still using the

same processor and OS that has proven itself in the field.

All S-series I/O cards run the latest software enhancements of corresponding

M-Series I/O cards and deliver the same field proven, reliable operation.

Designed for Digital Marshalling.

The S-Series controllers have highly distributable I/O capabilities with CHARMS based Electronic Marshalling.

Electronic Marshalling I/O can be mounted anywhere, facilitating system design and expansion

while reducing overall system footprint over traditional marshalled I/O Subsystems.

Advanced Controls.

The SD Plus controller supports all the advanced control features that are expected in a world class Digital Control System:

 Batch Software

 Model Predictive Control

 Neural Networks

Easy to use.

Controllers are also easy to configure. Simply connect the SD Plus to the DeltaV network and Auto-Sense it from DeltaV Explorer.

Add the controller and all its IO interfaces to the system database and all components are automatically addressed and communicating.

There are no dip switches or jumpers to set.

 Control strategies are developed using IEC-61131 programming techniques: Function Blocks, Sequential Function Charts and Structured Text.

 Automatic diagnostic and event reporting with time stamps applied in the controller

 Set control execution to match process dynamics and controller scheduling adjusts automatically.

 Reference any parameter by its module name, regardless of its location in the system.

 Synchronized system clock for consistent time based event driven actions across the system.

 Online expandable IO carriers allow new cards to be added online, with autosense capability, for modular system growth

 Hardware redundancy is automatically detected with zero configuration effort.

Benefits

Scalable controllers. The SD Plus controller complements the SX controller by providing

a smaller controller platform at a reduced price for those small to moderate applications:

 Speed. The SD Plus controller supports all the features you’ve come to expect from the DeltaV system: 

self-addressing, automatic I/O detection. All these features are designed to make your projects execute faster—just plug and play!

 Redundant architecture. The SD Plus controller supports 1:1 redundancy for increased availability.

Redundant SD Plus controllers can be upgraded to SX controllers online—robust!

 Late Changes. You can easily upgrade an SD Plus controller to an SX to handle project

scope changes late in the project. Simply replace the SD Plus with the SX and all existing configuration,

documentation and hardware design remain the same —forgiving.

Quick Assembly. The S-Series hardware has been redesigned for speed of project execution.

Carriers snap to standard DIN rails and controllers and S-series IO snap into position without the use of retaining screws.

DeviceNet Interface Cards

In DeltaV v12 and later, the number of DSTs per connected

DeviceNet device will be 1 DST in most cases. The DST type

counted will be the most valuable type used to reference

a signal for each device. If references are made to more

than 16 signals from a device, additional signal references

beyond the 16th reference will each count as a DST.

A motor starter, for example, with 4 to 5 signal references,

will consume 1 DST (typical an AI or DO DST). A remote I/O

island will consume 1 DST for the first 16 signal references,

and 1 DST for each additional signal reference beyond the

16th signal reference.

Profibus DP Interface Cards

In DeltaV v12 and later, the number of DSTs per connected

Profibus DP device will be 1 DST in most cases. The DST

type counted will be the most valuable type used to

reference a signal for each device. If references are made

to more than 16 signals from a device, additional signal

references beyond the 16th reference will each count

as a DST. A motor starter, for example, with 4 to 5 signal

references, will consume 1 DST (typical an AI or DO DST).

A remote I/O island will consume 1 DST for the first 16

signal references, and 1 DST for each additional signal

reference beyond the 16th signal reference.

DeltaV Licensing Guidelines

DeltaV I/O licensing for the VIM2 depends on the I/O cards

the VIM is emulating and follows that card type’s rules.

Programmable Serial Interface Cards

Serial dataset registers can be referenced directly in control

modules as analog or discrete I/O providing fast easy data

exchange with the serial device. Direct module-to-Dataset/

register references are recommended for control signals.

Alternatively, users can read multiple registers from a

Dataset into a single “marshalling” module at the cost of a

single DST. Marshalling modules provide a cost-effective

way to integrate serial data from analyzers and other data

sources. Serial dataset registers can also be passed as

SCADA values directly to Workstations and Continuous

Historians without consuming DST’s.

See the M-series Serial Interface Series 2 product data

sheet for additional details.
