Introduction

Honeywell TDC 2000 and TDC 3000 systems have provided excellent control for many years. However, the aging components of these systems are mostly obsolete and often unavailable to many users. Maintenance programs (such as SE&SP) are costly without necessarily satisfying your needs and these costs may outweigh benefits of keeping the legacy system. Struggling with basic system maintenance puts you in a weak position when negotiating for system expansions or process optimization using advanced control applications – both of which require additional equipment and the advanced controls require interface development, as well. Bringing the legacy system up to current software revision is expensive and usually requires hardware upgrades. Yet, coming current does not necessarily provide compelling new capabilities that help you advance beyond your competitors.

Emerson offers excellent migration services and products to facilitate low risk, low maintenance system improvements that help you derive greater benefits from your existing TDC system and plan for a full transition to the DeltaV system and PlantWeb at your own pace. Emerson personnel understand the TDC systems and work with clients to determine the best options for your site, from total system replacements (in phased approaches) to standalone DeltaV systems for new plant areas. These standalone DeltaV systems can integrate with other plant systems more easily than can any other control system. This paper describes how to connect the DeltaV system with TDC systems and the benefits of each connectivity option. There might be a few paragraphs in this section.

Connecting

Not shown below is the revolutionary DeltaV Connect™ Solution for Honeywell® Systems. This unique solution makes DeltaV Operator Stations the Human Machine Interface (HMI) for the Honeywell TDC controllers and I/O, and more information about this solution can be found here.

For basic interconnectivity, Honeywell and DeltaV systems can share data by several methods. Figure 1 show TDC 2000 connectivity options:

Figure 1—DeltaV to TDC 2000 Connectivity Options


Figure 2 shows connectivity options for DeltaV systems with TDC 3000:

Figure 2—DeltaV to TDC 3000 Connectivity Options

As shown above, Object Linking and Embedding (OLE) for Process Control (OPC) allows for data exchange between a DeltaV system and a Honeywell system. Various serial interfaces also allow for data exchange between the two systems. FlexConnect® solutions provide hardware boards and/or cables that preserve device wiring up through the Honeywell I/O terminations. The next few sections explore benefits of each method.

OPC for Data Exchange

OPC simplifies the task of sharing data between systems with different operating systems and data types. An OPC server gets data from a source, such as a control system, puts the data into a standard format, and makes it available to be read by an OPC-compliant client. Normally, OPC servers provide data to clients only; however, the DeltaV OPC Mirror enables data sharing between OPC Servers.

The DeltaV OPC Mirror then can serve data from various sources up to an OPC client. For instance, one OPC client can see data from TDC 3000 and DeltaV systems in one common format.

Benefits

OPC Mirror can link to all plant subsystems with OPC servers, in addition to the Honeywell control system.

Data historian or information management software can access multiple process control systems through one common interface protocol, OPC.

You can select applications by functionality, rather than by conformance to a proprietary communication protocol.


Allows operation of a limited number of Honeywell points from a DeltaV workstation and control a limited number of DeltaV points from a Honeywell console. Your Team Emerson Account Manager can show you a video showing this interoperability.

You get seamless integration with Microsoft and other OLE compliant applications.

You realize reduced integration costs—applications already speak the same language; so developers spend no time creating interfaces.

Architecture

Figure 3 shows an example of OPC interface architecture and the software required.

Figure 3—OPC Connectivity between DeltaV and Honeywell Systems

Serial Interface

Serial interfaces have been in use for many years. Typically, serial interfaces use a Modbus protocol and drivers must be written for the applications on both ends of the serial link. Special hardware for the serial type I/O is also required.

Serial links between Honeywell TPS and DeltaV enable operator actions performed at one system to result in control actions in the other system. Honeywell TPS has three types of serial interfaces, first via the PLC gateway (also EPLCG), secondly, using IOP/FTA serial ports within the APM/HPM and third, connecting via the TDC 2000 DHP (Data Hiway Port). For all of these, the DeltaV requirement is simply a serial I/O card with serial communications terminations and the appropriate (Modbus) protocol.

Benefits

Serial connectivity is a reliable and well known data exchange method that allows monitoring and operation of Honeywell control data from a DeltaV workstation. Serial interface implementation allows data to be brought directly into a DeltaV controller. Thus, the points become DeltaV tags.


Performance

Per Honeywell technical specifications, an I/O subsystem, such as IOP/FTA for the APM/HPM has two serial ports per IOP. Each serial port can support <= 10 writes per second and <= 2048 Boolean, 32 integer, 64 real, or weighted combinations of these reads per second. Each Honeywell PLCG has two serial ports with a capacity of 3000 points per gateway. Data acquisition performance depends primarily on the PLC response to requests by the gateway. Point scan rate is 500 points per second, and may be up to 1000 points per second when digital points dominate the point type mix. Maximum capacity for each PLCG by point type is shown in Table 1.

Table 1. Maximum Capacity for PLCG Serial Interface

Capacity Point Type

3000 Digital inputs

1920 Digital inputs

1280 Digital composites (one in, one out)

1440 Analog inputs

960 Analog inputs

576 Analog composites (one in, one out)

50 Critical alarms

600 Events

500 Point contact cutouts

Output requests from other control network nodes go into a stack for “first in, first out” processing. Rates vary with the frequency of requests from all nodes on the control network that are interrogating the PLCG. While adequate for monitoring, this data exchange rate may be insufficient for control across links between the two systems.

DeltaV Connect™ Solution for Honeywell® Systems

DeltaV Connect Solution for Honeywell Systems is a low risk, low maintenance option to preserve customer controllers for a period of time, while replacing the HMI immediately with a state-of-the-art DeltaV system, using familiar looking graphics, faceplates and detail displays. This solution enables you to continue using the TDC control and I/O for uninterrupted processing. Adding DeltaV interface stations to the Local Control Network establishes the ability to communicate between the systems. The DeltaV system network is then expanded to include DeltaV Operate HMI stations at a minimum. You can also add a historian and workstations that perform advanced controls such as model predictive and neural applications.

Benefits

Links to the Honeywell Local Control Network (LCN) and therefore has direct access to all the points & alarms communicating on that network

NOT an OPC solution, it is a unique/exclusive interface connecting directly on the LCN

Interface does not appear as an LCN node, but communicates as one

NO Honeywell system configuration required

NO shutdown of LCN nodes required


Does NOT require updating older versions (e.g., R5xx) to latest release

Reduces # of nodes on LCN, as Universal Stations are removed

“Connect” & manage multiple LCN’s data & alarms within the DeltaV system

Interface redundancy provides diagnostics for monitoring health status of standby station and minimizes the impact of hardware failure on plant operations

Operate Honeywell control points from a DeltaV workstation

Seamless integration

Honeywell Universal Station (US)-style instrument faceplates provided, easing the learning curve for personnel

Standard configuration tools and methods—no interface “programming” required

Architecture

The DeltaV Connect Solution for Honeywell Systems architecture is shown in Figure 4:

Figure 4—DeltaV Connect Solution for Honeywell Systems directly connects to the LCN


Performance

Actually reduces traffic on the LCN (compared to an equivalent US/GUS); it does NOT increase it.

Alarm annunciation is equivalent to a Honeywell station.

Small server supports up to 2,000 tags; large server supports up to 6,000 tags redundant or up to 10,000 tags in simplex mode.

Multiple redundant servers may be attached for larger LCNs.

FlexConnect® Solutions Save Device Wiring, Minimize Down Time

As the Honeywell controllers and I/O are replaced, if the associated field devices are not being replaced, the DeltaV controllers can connect directly to the Honeywell system’s I/O terminations. This is done using FlexConnect solutions, a special set of cables, interface panels and pass through cards that transform Honeywell field wiring terminations into DeltaV terminations.

Benefits

The most compelling of FlexConnect benefits is the dramatic reduction in downtime – which can be 75% or more—versus rewiring. Another benefit is lower wiring costs; they drop by 50% when using FlexConnect versus rewiring. Table 2a shows wiring costs for a conventional switchover, based on 640 I/O channels.

Table 2a. Cost impact of A 640-channel system switchover, conventional method

Total time required per channel 43 minutes/channel

Total installation for 640 channels 458 hours

Labor costs @$50/hour $22,900

Downtime (not including documentation time) 20 days

Table 2b shows wiring costs using FlexConnect solutions. Compare the downtime with that listed in Table 2a:


Table 2b. Cost impact of A 640-channel system switchover using the FlexConnect solution

Document 4 minutes/channel

Total time required per channel 21 minutes/channel

Total installation for 640 channels 224 hours

Labor costs @$50/hour $11,200

Downtime (not including documentation time) 5 days

During planning the installation and startup of the DeltaV system with an existing Honeywell system, the FlexConnect solution makes a phased implementation entirely feasible. Phased startups let you plan and execute switchover of your most critical plant areas first, while keeping other areas running.

Architecture

FlexConnect adds cables and/or panels between Honeywell I/O and a DeltaV controller. Some solutions include special terminal strips designed for quick assembly and installation. The exact structure varies with the type of system and the type of I/O. The DeltaV FlexConnect solutions for TDC 2000 and TDC 3000 are shown in Figure 5:

One method uses the removable termination strips on the field termination assembly (FTA). Compression terminations can be physically removed from the Honeywell I/O card and inserted onto the FlexConnect panel. Another method uses the IOP cable connection, keeping the FTA in place.

The screw terminal type I/O can be seated on the FlexConnect board, in place of the compression terminations. With this type of connection, the raw field signal is brought directly into the DeltaV controller, which allows HART pass through. The AMS Suite™ Device Manager capability in the DeltaV workstation is then accessible to these devices for monitoring and diagnostics. Table 5 shows the TDC 3000 Field Termination Assemblies for which FlexConnect solutions have been developed. (Next page)

FOUNDATION Fieldbus for LEPIU

For the TDC 2000 Low Energy Process Interface Unit (LEPIU) remote multiplexer I/O, a simple and elegant transition solution is to use the FOUNDATION fieldbus device Rosemount 848T. Each MUX has a capacity for up to 16 inputs and up to 16 remote MUX boxes per LEPIU.


Benefits

This solution allows you to re-use existing shielded twisted pair wire as the FOUNDATION fieldbus home run cable to a DeltaV H1 card.

Architecture

Figure 6 shows an example of the architecture for the multiplexer replacement with the Rosemount 848T:

Figure 6—LEPIU Replacement Solution with Rosemount 848T to DeltaV H1 Card

An even newer solution is to replace the MUX box completely, and rewire directly to new wireless 848Ts.

Profibus DP for TDC 2000 and TDC 3000 Discrete

The TDC 2000 TCB50 and TCB60 and the TDC 3000 FTA discrete I/O can directly connect to Profibus DP modules from either Microsmith or Phoenix Contact. The DeltaV Profibus card connects directly to the Microsmith or Phoenix Contact module, providing a complete path for this I/O to the DeltaV system.

Architecture

Figure 7 shows the architecture for TCB50 and TCB60 discrete to connect to a DeltaV Profibus DP card, using a Phoenix Contact module. Figure 8 shows the architecture for FTA discrete to connect to a DeltaV Profibus DP card using Microsmith modules. (Next page)


Figure 7—DeltaV Profibus DP to TDC 2000 Discrete I/O Figure 8—DeltaV Profibus DP to TDC 3000 Discrete I/O

Benefits

This solution allows you to bring large quantities of discrete through single cable connections into the DeltaV system. You use standard DeltaV engineering tools for the Profibus DP I/O configuration.

Transition Services

Transferring the required I/O and regulatory configuration from a Honeywell system to a DeltaV system requires careful oversight by engineers who understand both systems. Emerson has migration teams that:

Are focused exclusively on conversion services

Are experts who understand configuration in both DeltaV and TDC systems

Are familiar with common errors in conversions

Oversee use of tools

Provide new or enhanced design services

Control Database Conversion

Engineering database transfers are accomplished most efficiently by using a set of conversion tools. Automated tools reduce manual errors and provide expedient entry of required I/O assignments. These are used to the extent possible, based on the system. For instance, you get a TDC 2000 control database via a printer port capture; to get the TDC3000 control database, you export Exception Build files. Either database is then converted to a spreadsheet or Access database and then imported into the DeltaV Bulk Edit Tool.

DeltaV Connect Solution Database Conversion

Fully automated conversion services are included with the DeltaV Connect solution. This gives you an initial configuration on which you can expand your DeltaV network.


Display Conversion

TDC displays can be recreated for the original look and feel on the DeltaV Operate workstations. This speeds the learning curve for your operators, but doesn’t allow for newer graphic technologies, nor accommodates more recent customer or industry graphic standards. TDC 2000 EOS displays are converted manually, as are TDC 3000 GUS displays. However, TDC 3000 US display conversion utilities take these displays directly into the format required for the DeltaV system. With any DeltaV project, US style faceplates can be implemented, again to help operators acclimate to the new DeltaV system. Figure 9 shows sample US style faceplate and detail displays on a DeltaV Operate station. These faceplates and detail displays are automatically used for DeltaV Connect™ Solution for Honeywell® Systems.

Figure 9—US-style Faceplate and Detail Displays on DeltaV Graphics

Figure 10 shows GUS style faceplates on the DeltaV system, with standard DeltaV buttons for fast one-click access to detail, process graphic, trend, engineering, history or alarm summary displays.

Figure 10—GUS-style DeltaV faceplates


A user-configurable keyboard allows you to customize display navigation to suit your process needs and operational philosophy. A sample operator keyboard is shown in Figure 11; you can reproduce the familiar “USlook” keyboard if desired. Figure 12 shows how this keyboard might be installed with your consoles:

Figure 11—DeltaV User-configurable Operator Keyboard

Figure 12—DeltaV Consoles with Operator Keyboard


With a new DeltaV system, you have several options that can help ease the adjustment and minimize errors in the early learning phases. One of the first considerations is the type of people who will manage and execute the transition. Emerson offers a mature suite of services to help make all control system transitions successful. Emerson engineers and project managers are experienced with Honeywell to DeltaV upgrades. They have implemented successful hot cutovers, as well as performed site checkout and system startups during tight turnaround periods. For details about how customers have benefited from Emerson expertise when upgrading from their Honeywell systems, visit DeltaV Solutions for Honeywell Systems and to learn more about Emerson service capabilities, visit Emerson Process Solutions.

Other considerations are training your personnel and providing tools that facilitate quick adoption of the new technologies. As your project progresses, with DeltaV database configuration and graphics complete, you will have the tools needed for training operators on the new system. DeltaV Simulate Pro can provide realistic field responses to operators without connecting to real I/O. In a safe and virtually risk-free environment, operators can practice running the familiar process from the new DeltaV system. For all system sizes Operator Training solutions are available to suit the specific needs of your site and personnel. Emerson also offers custom courses either at your site or in their training centers. For more information about these powerful training systems, please visit DeltaV Operator Training Solutions.

Reference sites are available for all of the solutions described in this white paper.
