Centum XL OPC Server requires a gateway, the ECGW3. This device, if available at all, may be quite expensive. If customer does not already own an ECGW3, then this solution may not be practical, economically. Collection of process values and alarms No Shutdown is requiredCentum-XL OPC Server can communicate with DeltaV OPC server via OPC MirrorThis enables data sharing for bringing controller info onto a common display Supports redundancy on DeltaV side if redundancy is established on CS3000 side Security settings on CS3000 OPC server must be re-configured to allow communication Throughput & robustnessconcerns >5,000 points Recommend < 2500 points/OPC pipeOPC Redundancy is available as an option.An OPC point does not equate a signal Tag, an OPC point can be a parameter within a signal tag; i.e. SP or PV. A tag point can contain several OPC points.In addition to process data, alarms and events can be pushed as well through the OPC pipe.Factors that can drive the cost up include: Adding an OPC server on the PLC side if one is not available alreadyThe amount of software configuration needed is significant (large amount of modules and graphics to be created in DeltaV)Applications involving redundancy across multiple PLC servers. Best Fit:For applications where no more than 3000 points/OPC pipe are configured. This is to avoid bandwidth problems.
Why install a new system versus modifying the control strategy in the existing system?

Migration Issues for Management<br />What do we need to do?<br />What do we gain by modernizing the automation system?<br />Who can do this for us? (plan / design / implement / start-up)<br />How much will it cost?<br />How long will it take?<br />How long does the process need to be shutdown?<br />What are the other risks of the process not starting back up on time and in spec?<br />How are the risks mitigated?<br />
Migration Projects Differ from New Projects<br />Documentation may not be readily available or up-to-date<br />Automation hardware needs to fit into existing equipment or free space<br />Small window for installation shutdown or requires hot cutover<br />May need to do project in phases<br />Intensive testing is absolutely necessary to ensure successful start-up <br />Operational improvements derived through better automation are expected<br />
Migration Strategy: Options to Consider<br />As-Found – Migrating “EXACTLY” what is in the legacy system to DeltaV<br />Functional – Migrating the “FUNCTIONALITY” of the legacy system to the DeltaV system using today’s technology<br />Modernization – Applying state of the art applications, including field devices, in addition to functional migration to achieve “BEST IN CLASS” benefits<br />
Migration Scope Options to Consider <br />Replace the entire automation system at one time<br />Cold Cutover<br />Completed Replacement (including field terminations)<br />Marshalling System (minimizing downtime)<br />Hot Cutover<br />Phased approach<br />Vertical (Process Area)<br />Horizontal (Platform Focus)<br />HMI interoperability (Controller and I/O remain)<br />Controller replacement (I/O remain)<br />I/O Card replacement (Field terminations remain)<br />
Hot vs Cold Cutover: Key Economic Driver<br />Cold Cutover <br />Engineering & construction perspective <br />Potential for plant upsets minimized or eliminated<br />Safety Hazards greatly reduced<br />Environmental releases eliminated<br />Manpower/resources deployment flexibility<br />Uncertainties of BAD data reduced (instrument or process problem?)<br />Hot Cutover<br />Economics (no production loss)<br />Operations Perspective: process problems typically taken out of equation, smoother transition <br />Operator & Maintenance Training are simplified, one-on-one<br />Eliminates time-consuming, expensive, and dangerous start-ups (Continuous Industries)<br />
Vertical vs. Horizontal Approach<br />Vertical Migration – Based on migrating one complete automation system/area at a time<br />Horizontal Migration – Based on migrating “equipment type” at a time across automation systems <br />Decision Factors – Operating Philosophy <br />Interim Journey: Operate 2 systems for some period of time?<br />Plant Area at a Time: Can you divide up by Controller or Control file at a time ?<br />Segregated I/O: How is I/O laid out in cabinets? Interchange within areas? How is spare capacity used?<br />Best Practice: Detailed/Meticulous site audit of hardware/field wiring terminations <br />
Additional Drivers that Direct the Migration/Modernization Approach<br />Capital budget restraints<br />Production / Shutdown schedule constraints<br />Legacy system infrastructure layout<br />Free space constraints<br />Equipment obsolescence status<br />Justification driver <br />

Design for the Justification Driver<br />Understand the business objectives<br />Review historic plant performance<br />Audit existing process for poor performance and variability <br />Define opportunities for improvement through automation<br />
Items to Consider for Operations: Performance Improvements<br />Equipment utilization / efficiency<br />Performance variability<br />Poor control loop performance<br />Too many loops in manual<br />Manual actions that are done inconsistently by operator choice<br />Scheduling difficulties<br />Manual paperwork <br />
Modern Control System Features<br />Ease of use to apply more complex control strategies and flexibility to easily modify strategies<br />Built-in batch sequence control with S88 standards<br />Built-in tools to monitor equipment and control loop performance <br />Platform for gathering process unit information and easy integration to Plant ERP systems<br />
