Ordering Information (Cont’d) 

Cables are available in lengths required for your migration 

project. These cables can be pre-wired and tested to DeltaV I/O 

terminal blocks. These custom loomed cables are all connected 

to the nosecone adapter on one end, open-end / flying lead on 

the other end, all open wires marked with the corresponding 

pin number and have ferrules on each wire, 18-22 AWG can be 

specified, and flying-lead to connect to the DeltaV I/O. Contact 

your local Emerson representative for pricing and availability. 

Prerequisites 

A preliminary site visit is required to survey installed control 

system architecture and electrical grounding practices, to 

document I/O models and numbers of each, and to review 

schedule constraints and turnaround objectives. Qualified 

Emerson engineers or technicians perform site reviews.

For help in planning, justifying, or implementing your system 

migration, contact your local Emerson representative. Expert 

consultants are available to advise you on a variety of concerns, 

including safety system design, implementation and standards 

compliance, digital buses, wireless applications, control performance, 

and process optimization.

◼ Reduce business risks by minimizing process downtime 

◼ Save on installation costs 

◼ Preserve HART® signals  

Introduction 

If concerns about downtime and wiring costs are preventing 

you from migrating your Foxboro™ I/A Series 100 I/O to a new 

DeltaV™ system, consider DeltaV Flex.Connect solutions for 

Foxboro I/A Series 100 I/O. 

Benefits 

Reduce business risks by minimizing process downtime. This 

solution brings device signals to DeltaV I/O from existing Foxboro 

I/A Series 100 Fieldbus Modules (FBMs). Keeping device 

wires intact accelerates the new system startup, enabling you to 

rapidly resume production. 

Save installation costs. Eliminating new device wiring saves money 

and reduces the risk of errors. Time and material savings are 

significant. 

Preserve HART signals. Use HART® Pass-through for complete 

diagnostics at the DeltaV workstations.

Retain Valuable Intellectual Property 

While Improving Control Performance 

with Tool Based Database and  

Display Analysis

Striking a balance between complete reverse engineering and 

starting design from scratch is achieved by taking a Forward 

Engineering approach which is enabled by using analysis tools, 

purpose built for the legacy platform. For Foxboro I/A Series 

Systems, a tool-set is available for both the control database 

and FoxView displays. Parsers extract the raw data and 

sophisticated algorithms produce reports from detailed I/O lists 

to an assessment of complexity, class-based versus custom code 

and much more. These outputs are designed to allow engineers 

to assess reusable code, such as base level loops, motors,  

valves etc. and complex logic structures which might be 

improved by redesign in a modern system. For example,  

the use of equipment modules can make operation, 

visualization and troubleshooting much easier than “spaghetti” 

function block code. Tools are transforming some traditional 

manual workflows into digital workflows which increases 

project efficiency, ensures the required functionality is  

achieved with a modern design and reduces the risk of errors  

or a flawed implementation. For your business, this translates 

to a faster ramp-up to full production, improved controls, 

confident operators and maintenance staff.

Maximize capital efficiency

With robust processes, tools and with the right technology, 

Emerson can deliver modernization projects that are low risk 

and make best use of your capital. We can help manage scope, 

reduce or eliminate engineering and design work, reduce space 

requirements, and ultimately deliver the value you should 

expect from the world’s leading distributed control system.

Solutions for Legacy Foxboro  

I/A Series Systems

Reduce Downtime by Up To 75%  

with FlexConnect®:

When downtime must be kept to a minimum,  

FlexConnect solutions allow existing field terminations  

to remain. This saves time and reduces the cost of  

rewiring. Solutions are available for both FBM 100 series  

and 200 series I/O.

For FBM 100 series, the nosecones are retained along with the 

existing field I/O terminations. An adapter is connected to the 

nosecone and the signals are routed to DeltaV I/O modules  

via cables which will typically be pre-wired at the factory for  

the shortest possible cutover.

Emerson’s technology can help

DeltaV technology provides unprecedented flexibility  

to work within the constraints of brownfield projects.  

Electronic marshalling can be installed almost anywhere,  

can be highly distributed, and with over 40 I/O wiring options  

it can handle all the signal types existing in your facility. 

The PK controller has the capacity to handle all the basic 

process control functions PLUS advanced control, sequences, 

state-based control, and batch logic. It can also be deployed 

in smaller, standalone applications, and with built-in Ethernet

based connectivity, it can easily integrate data from 3rd party 

devices like PLCs and drives and can easily provide data to 

enterprise applications. 

Brownfield Solutions

On top of this, Emerson has a vast catalog of solutions 

specifically designed to aid in modernizations. The FlexConnect 

Solutions portfolio speeds up cutover and avoids re-termination 

of field wires. Emerson’s Alliance Program includes a  

portfolio of tested gateways that help phase the transition  

to DeltaV. And for the software transition, Emerson has a  

world-class set of tools to enable a modern, maintainable, 

functional implementation of the control strategy while 

retaining important intellectual property from the  

legacy system.

Emerson is the lowest risk option

With over 6000 transitions to DeltaV from all types of  

legacy systems, Emerson has the experience to solve  

any challenge. Utilizing established processes, our subject 

matter experts will assess the state of your automation,  

quantify operational benefits, and justify, plan, and execute 

your project. Emerson has over 5000 project resources 

worldwide along with dedicated Modernization Teams  

to ensure your project is executed flawlessly, on schedule,  

with minimum production impact.
