Configuring SIDirect DAServer to Communicate with S7 PLC Over TCP Connection

The SIDirect DAServer provides access to data within the Siemens S7 200, S7 300, and S7 400 PLC families through a standard EtherNet network interface card without requiring Siemens SimaticNet software. The SIDirect DAServer is capable of DDE, FastDDE, SuiteLink™, or OPC connections to Windows® client program such as an InTouch® application.

This Technote provides a step-by-step procedure of how to configure and use Wonderware’s SIDirect DAServer with a S7 PLC (S7-400 PLC is being used in this technote) via DDE/SuiteLink protocol.

Before you continue, make sure the following requirements have been met:

  • Read and follow the instructions in the SIDirect DAServer’s readme file and related documents for System requirements, proper installation procedures, and supported Operating systems.
  • Install the latest version of the SIDirect DAServer. If a previous version was installed, uninstall it using Add/Remove Programs in the Control Panel. This technote is written using SIDirect DAServer version 1.0.0.
  • Install and configure TCP/IP network protocol and the network interface card (NIC)
    so that it can communicate with the PLC via Ethernet.
  • Make sure that you can “ping” the PLC successfully and receive valid replies from the PLC.

Note: Please check the SIDirect DASERVER Online Help for more information about the supported firmware and hardware. Only the TCP bus communications protocol is supported by the SIDirect DAServer. The SIDirect does not support MPI, Profibus, and other non-EtherNet protocols.

Configurating the SIDirect DAServer

  1. Start the SIDirect DAServer Manager by selecting Start/Programs on the taskbar.

  2. Navigate to the Wonderware folder that contains the System Management Console, then click System Management Console.
  3. From the ArchestrA System Management Console (SMC), find the SIDirect DAServer in the DAServer Manager tree. Under the local node the DAServer name is ArchestrA.DASSIDirect.1 (Figure 1 below).


    Figure 1: DASSIDirect DAServer in the SMC

  4. Expand ArchestrA.DASSIDirect.1 and highlight Configuration.

    The Global Parameters dialog box will appear as shown in Figure 2 (below):


    Figure 2: DASSIDirect – Global Parameters

    Device Group Update Interval: Specifies the update interval of the default device group.
    Slow Poll Interval: Specifies the interval that the DAServer polls the field device after it goes into slow poll mode when connectivity problems occur. The DAServer will be governed by device group update intervals when the communication returns to normal.
    Transaction to Subscription Ratio: Transactions are poke/read messages from a DDE/SL/OPC client. Subscriptions are messages generated by items being on advise. Subscriptions are sent periodically at the Update Interval.

    The Transaction to Subscription ratio defines the maximum number of transactions the DAServer sends before sending one subscription. It is the ratio of transaction to subscription messages when there are several transaction messages pending. The second half of the ratio is always 1. Therefore, the default ratio 2 means 2:1 transaction to subscription messages. The ratio ensures that a certain amount of subscription activity is guaranteed even in a transaction overloaded state.

    For example if the ratio is set to 2 and there are 3 transaction messages and 2 subscription messages become due at the same time, the toolkit will send out 2 transaction messages, 1 subscription message, 1 transaction message and then 1 subscription message.

    Transaction Message Timeout: The timeout for transactions (read/write/refresh/property) per message. This timeout prevents a client from hanging in a transaction forever if for some reason the transaction messages are never scheduled until completion. It is the maximum amount of time between message updates within a transaction. The timeout has to be set in such a way that under no circumstances data acquisition on an individual message takes longer than this timeout.
    Server Protocol Timer: This option is disabled, since the SIDirect uses event driven protocol engine.
    Diagnostic Backlog Size: Specifies the maximum number of transactions shown in the Transactions diagnostic root.
    Poke Mode: The following modes are available:
    – Control
    Mode preserves the poke order without folding.
    – Transition
    Mode preserves the poke order with minimum folding by keeping the first, second and last poke values of an item.
    – Optimization
    Mode does not preserve the poke order and has maximum folding by only poking the last value of an item.

    Case Sensitive: Controls how the DAServer scans item and device group names with respect to upper/lower case.
    Device Group Cache: This parameter is for future use.
    Simulation Mode: This parameter is is disabled for the SIDirect DAServer.
    System Items: This parameter controls whether the system items appear in the browse interface and if they are recognized as valid ItemIDs by the DAServer’s data acquisition interfaces.
    Unique Device Groups: This parameter controls whether the device group names are checked for uniqueness across all device nodes of a DAServer.

  5. Right-click the Configuration icon.

  6. Select Add PortCpS7 Object from the sub-menu.

  7. Right-click New_PortCp_000, and select Add S7Cp Object. The S7 CP parameter dialog window appears as shown in Figure 3 (below):


    Figure 3: S7 CP Communication Parameters

    Network Address: Enter the IP address for the PLC. The S7 PLC used in the example of this technote has IP address of 192.168.10.41.
    Local TSAP: Specifies the local station’s transport service access point. The first digit specifies the device, and the second digit should be zero (0). Recommended setting is 01.00.
    Remote TSAP: Specifies the PLC’s transport service access point.
    Remote Rack No: Enter the decimal number for the Rack.
    Remote Slot No: Enter the decimal number for the Slot of the CPU.

    The example in this technote uses the rack number 0 and the slot number 3 , where the S7-400 CPU is located. (The power supply takes up two slots, so the CPU is in slot 3.)

    Connection Resource: Select the Hex number for the Connection Resource from the drop-down menu.

  8. Select the Device Groups tab.
  9. Right-click on the white space in the Device Groups dialog box to add a device group ( similar to Topic Definition ) in the Device Groups dialog box as shown in Figure 4 (below):


    Figure 4: Device Group Dialog Box

  10. Select, then right click the default Topic_0 to rename it to some meaningful name such as S7PLC as shown in Figure 5 (below):


    Figure 5: S7PLC Device Group

  11. In the hierarchy tree on the left pane, right-click ArchestrA.DASSIDirect.1 and select Activate Server from the sub-menu to start the DAServer. The icon next to ArchestrA.DASSIDirect.1 will change from red to green as shown in Figure 6 (below):


    Figure 6: SIDirect DAServer is Activated

Testing the DASSIDirect Server

The DASSIDirect Server is ready for use. We are now going to do a quick communications test to verify that we can establish the connection to the PLC.

  1. Click Start/Run and enter WWClient to start the Wonderware WWClient program.

  2. Select Connections/Create from the main menu. The Create Connection dialog box will appear.
  3. Enter appropriate information as shown in Figure 7 (below), where:
    Node: blank since the DASSIDirect and the WWClient are on the same computer. Otherwise, enter the computer name of the machine running the DAServer.
    Application: DASSIDirect, which is the application name of the SIDirect DAServer.
    Topic: S7PLC, which is the exact name of the new device group we just created in the DASSIDirect’s device groups window.
    Connection Type: IOT which is the SuiteLink protocol used for this technote.


    Figure 7: Create Connection Dialog Box

  4. Click Create, then Done.

    The WWClient window should now appear similar to Figure 8 (below):


    Figure 8: WWClient Showing Connection with the DASSIDirect

  5. Select Item from the main menu.
  6. Enter a known good PLC register address.

    The following figures show an example of WWClient successfully advising item MB90 from the S7 PLC. Enter MB90 in the Item entry box. Click the AdviseEX button to register and advise the item. If the Ethernet connection to the PLC is good, you should see the value for the register MB90 as shown in Figures 9 and 10 (below):

A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.

Technology Update: SCADA evolves toward MES

Today’s SCADA systems are evolving beyond supervisory control and data acquisition with greater functionalities and integration capabilities.
In Food Engineering’s 2001 Best Manufacturing Practices Survey (Feb., ‘01), only five percent of respondents reported having SCADA systems in their plants.

We thought that surprisingly low. The problem may lie in the definition.

SCADA — the acronym and abbreviation for Supervisory Control And Data Acquisition — has become more difficult to define as these systems add more production-management and manufacturing-execution functions, blurring the distinction between SCADA and MES (Manufacturing Execution Systems).

The term SCADA emerged during the 1980s from the gas, oil and utilities industries, where it refers to remote monitoring and control of widely distributed plcs and I/O points in facilities such as oil fields, electric-power generating stations, water and wastewater-treatment plants. Eventually the term was applied in manufacturing plants to operator interfaces with processes directed by plcs. A typical SCADA system integrates plcs on the plant floor with a PC and might include some sort of man/machine interface (MMI).

Today, that integration increasingly includes HMI (human/machine interface), a PC with graphic process and machine-status displays, alarms, messages, diagnostics, data access, reporting tools and automated process execution, allowing operator feedback. “SCADA has become almost interchangeable with HMI,” observes Mark Richman, automation engineer at systems integrator Tri-Core, Inc., Racine, Wis.

John Blanchard, principal analyst at the ARC Advisory Group (Dedham, Mass.), Sees two trends contributing to the growing functionality and upward evolution of HMI/SCADA systems. “First, the MMI (man/machine interface) market is flat — anybody can do it. So the only way for the vendor to build his business is to take-on more functionality,” Blanchard points out. “Second, by doing that, they’re becoming more and more the interface to what’s usually called the ERP systems. By definition, that becomes MES. So there’s a business trend evolving here that puts them in the middle.”

Process control & batch execution

Major software vendors today offer turnkey HMI/SCADA systems, and systems integrators can either install turnkey solutions or customize systems integrating components from various vendors. Tri-Core, for example, can install complete HMI/SCADA packages from Rockwell, Intellution and Wonderware, or provide tailored solutions not available from any single vendor.

In determining which type of system to install, “customer requirements are the first and foremost consideration,” says Richman. “Cost is always a consideration. And where you’re trying to control certain portions of a process, the project may not be big enough to support a full-blown HMI, so you’d probably put in something like a panelview or Quick Panel or some other type of OIT (operator interface terminal). The HMI is often used in a lab or office, but we put them in NEMA 4X enclosures (to resist washdown) on plant floors as well. So the basic considerations on any project are customer requirements, cost, and the complexity of the system.”

One recent example of a Tri-Core HMI/SCADA project is the installation of a Rockwell rsview32 system at the Portion Pac, Inc. Plant in Mason, Ohio. Portion Pac, a unit of H.J. Heinz Co., Manufactures flexible and rigid single-serving packages of ketchup, salad dressings, sauces and other condiments for food-service markets. The plant operates three batch processes — one for ketchup, one for salad dressings, and one for specialty condiments — each controlled by a separate rsview program integrating four Allen-Bradley SLC 5/05s which govern each process from batching up to the filling machines. According to Richman, system architecture consists of a server PC and a client PC in the ketchup area with another client for the salad dressing operation, and a second client/server system for the specialty process, all linked via Ethernet.

“The former system was just mechanical relay logic, so there was no PLC control whatsoever,” says Bob Lindhorst, plant engineer at Portion Pac. “Now there are a lot of visual aids on the screen for much better operator interface.”

rsview controls recipe execution, batching, blending, heating, cooling, pasteurization, homogenization, pumps, valves, holding-tank levels and CIP, Lindhorst continues. Process variables such as pressure are controlled to minimize pump wear and reduce maintenance. “We can build recipes now; we couldn’t do that before,” he adds. “You just click the recipe and everything is automatic.” Because the programs for all three manufacturing areas are connected via Ethernet, any process can be monitored and controlled if necessary from any station.

Rockwell describes rsview32 as “an integrated, component-based HMI software package for monitoring and controlling automated machines and processes.” The system incorporates open technologies for connectivity with other Rockwell products, Microsoft products and third-party applications. “I would say that SCADA is a subset of today’s standard control systems,” says Darryl Walther, rsview32 product manager at Rockwell Automation (Milwaukee, Wis.)

Standards ease integration

The latest HMI/SCADA releases from major vendors are based on Windows NT, ‘95 or 2000 operating systems and embed Microsoft object technology standards (which minimize the time required to customize software to specific applications); open client/server standards (which allow integration with devices from multiple vendors); and web-based tools for integrating with upper-level business systems and throughout the enterprise. Major standards include:

  • OLE (Object Linking & Embedding);

  • OPC (OLE for Process Control), a client/server standard for communicating with devices from multiple vendors;

  • activex, Microsoft Component Object Model (COM) controls which allow sharing objects with larger programs or applications (called containers);

  • VBA (Visual Basic for Applications), a programming language for customizing applications;

  • ODBC (Open Data Base Connectivity) to integrate with relational databases via SQL (Structured Query Language);

  • SQL Server, Microsoft’s relational database.

All of these technologies are included in Windows DNA-M (Distributed internet Applications for Manufacturing), which links “islands of information” within a manufacturing environment and “bridges the gaps” between enterprise applications and supply-chain partners.

Several vendors have added “thin client” technology, which allows any client computer to access a SCADA (or other systems) residing on a central server for real-time access to HMI information throughout the enterprise. In other words, the HMI/SCADA software need not reside in client computers for a client to access all the functionality of the server.

Upgrades & applications

Among the HMI/SCADA systems which incorporate these technologies and more are Rockwell’s rsview32, Intellution’s ifix, Wonderware’s intouch , Ci Technologies’ Citect, National Instrument Corporations’ Lookout and Fisher-Rosemount’s deltav.

Intellution (Foxborough, Mass.) On Feb. 12 released ifix 2.5, the latest HMI/SCADA solution in its Dynamics family of automation solutions. The upgrade operates on Windows 2000 as well as NT and incorporates i clientts thin-server technology.

Dynamics, including FIX HMI/SCADA and visualbatch packages, integrates with other systems incorporating Microsoft DNA-M standards throughout Ocean Spray Cranberries Co. To empower operators making value-added on-line decisions and linking plant-floor automation with an SAP ERP system. As reported in Food Engineering’s 1999 “New Plant Of The Year” feature (June, ‘99), process control at the Hunt-Wesson Snack Pack Pudding plant in Waterloo, Iowa, consists of Allen-Bradley plcs, Intellution FIX and visualbatch software networked via Ethernet into a SCADA system.

deltav, the HMI/SCADA component of Fisher-Rosemount’s plantweb field-based solution, offers software options for data acquisition, calculations, sequencing, regulatory control and batch. In addition to OLE and OPC, deltav supports Foundation fieldbus and HART communications standards. Currently, Arancia Corn products is installing plantweb at its corn wet-milling plant in San Juan del Rio, Mexico, which produces glucose, dextrose and high-fructose corn syrup. In January, the Danish seafood packer Maritex selected plantweb for automating a new fish process at its plant in Vesteralen, Norway, north of the Arctic Circle. Fisher-Rosemount is based in Austin, TX,

Wonderware’s intouch Version 7.1, the HMI/SCADA upgrade to Wonderware’s factorysuite 2000 manufacturing-management information system, can also be accessed via thin-client technology and adds Internet integration to the plant floor, allowing execution of existing applications or design of Internet-specific applications. Tim Sowell, Wonderware’s director of marketing for factorysuite, concurs with ARC’s John Blanchard about the evolution SCADA toward the MES level. Wonderware ( Irvine, Cal.) Perceived in the mid-’90s that people wanted more out of SCADA than supervisory control and data acquisition, says Sowell. “They want data stored for longer periods of time, faster rates, larger volumes, uptime and downtime reports,” he continues. “People want to do benchmarking, discrete tracking and a whole lot more with plant data. If you consider what we have to offer today, the traditional SCADA has become a commodity.”

HMI/SCADA automates coffee-bean process

Lookout, a Windows NT-based HMI/SCADA software package from National Instruments Corp. (Austin, Tex.), Automates batch processing, recipe management, reporting and statistical process control (SPC) of coffee-bean blends while integrating with inventory management at Silocaf of New Orleans.

Silocaf, a unit of the Italian firm Pacorini Finanziaria S.p.A., Processes more than 550 million lbs. Of green coffee per year for major U.S. coffee marketers, accounting for about one-third of all U.S. coffee imports and a market value of $885 million.

The core of our operation is the batching system for blend production. Because coffee is a natural product and certain supplies are seasonal, consistency of blend flavors is difficult to maintain. We therefore offer customers the ability to blend coffee from different origins. We can achieve the desired consistencies only through accurate and complex mixing.

In the early ’90s, when we renovated a public grain elevator at the Port of New Orleans into a coffee-processing plant, we installed bulk-handling equipment including bucket elevators, chain-drag conveyors, bulk weighing systems, screening machines and aspiration channels to move, weigh and remove foreign material from coffee beans. By the end of 1996, we felt the need for a new supervisory control and data acquisition (SCADA) system which could meet the following criteria:

  • Exceptional recipe management, to produce custom blends;

  • Batch reports to match custom billing needs;

  • SPC control of batch processing to a blend accuracy of 0.5 percent;

  • Integration with our inventory management system, enabling us juggle inventories from a dozen different countries to meet custom batch requirements.

More general criteria included networking, computer redundancy, integration with a variety of plcs, and the ability to modify our software configuration on-line during batch production.

Lookout met these requirements and offered additional benefits. Lookout’s object architecture, for example, allowed us to configure the software to our application in less time than we expected. National Instruments also releases new seamless upgrades every few months, allowing continuous improvement.

Our entire plant is monitored and controlled by Lookout. Screen graphics symbolize and color-code the status of nearly 300 devices. More than 1,500 alarms alert operators to the status of any process in real time.

Three of the Lookout stations communicate over their own subnet in an NT Server LAN, which isolates the control system from the rest of the plant. One station acts as a server, communicating with the plcs and more than 5,300 I/O points over a local Tiway network. Operators at any client station can monitor and control the entire process. Redundancy allows one station to stand-by and take-over communication with the plcs should a fault occur in the primary server. When not acting as a server, the stand-by unit functions as a client.

The batching system consists of 52 automatic bulk-weighing scales, of which up to 24 can operate simultaneously. Lookout monitors and controls this system by communicating with several Siemens plcs.

Full integration of production information with our inventory-management system was achieved through object standards such as OPC and ODPC. As newer technologies emerge, SCADA systems continue to evolve.

SCADA boosts malt quality & throughput

A Citect SCADA system supplied by Ci Technologies (Sydney, NSW) helped boost annual malt production from 20,000 metric tons after startup in 1978 to 46,000 tons today at the five-hectare Kirin Australia plant, a malting unit of Japan’s Kirin Brewery at Welshpool, Western Australia (near Perth).

Kirin in 1995 decided to replace its existing Unix-based SCADA system with Windows-based client/server Citect software packages to achieve more accurate monitoring and control of its malting operation. Stage 1 of the project involved upgrading controls for the steeping and germination processes. Stage 2 continued the project by programming existing plcs to control barley receiving, barley cleaning, dry-hopper filling, malt cleaning and malt outloading, and replacing the existing SCADA with a Citect system consisting of two redundant workstations in the control room plus two field workstations, one at barley receiving and another at malt outloading. Stage 3 upgraded control of the kilning process.

According to cit, the Kirin technical staff reported “marked improvement in supervision and control of all essential variables.” Additional improvements

include remote monitoring and acknowledgement of alarms in unmanned areas; centralized production information, allowing better access and use of the information; improved inventory control and management.

According to Graig Adams of systems integrator PCT (Perth), which executed stage 2 of the project, Citect was installed to communicate with the existing Modicon plcs, “providing a ‘window’ into the plcs.” Temperature and humidity were among the variables improved to encourage barley germination. Citect improved screen graphics and dramatically reduced screen-information update time from 29 seconds to less than two seconds, Adams added.

The Kirin plant is currently upgrading its Citect systems from Version 4 to Version 5, released last year. Standard features include OPC client/server architecture, ODBC (Open Database Connectivity), SPC, Circode high-level SCADA programming language, and up to 170 device drivers for I/O communications and “capable of integrating with plcs from just about any other vendor,” says Brian Preston, marketing coordinator for Ci Technologies, Inc. (Charlotte, N.C.). On Dec. 20, cit released Citect Version 5.30, which features activex object support, alarm filtering to define alarms by user criteria, and remote I/O enhancements.

How to put SCADA on the Internet

Many companies are considering using the Internet for supervisory control and data acquisition (SCADA) to provide access to real-time data display, alarming, trending, and reporting from remote equipment. However, there are three significant problems to overcome when implementing an Internet-based SCADA system.

The first is that most devices used to control remote equipment and processes, such as gas production wells and power transformers, do not have Internet-communications capability already incorporated in their operating systems. In fact, many do not even have an electronic controller, let alone an operating system. The second is that the device still has to be physically connected to the Internet, even when equipped through retrofit or in the factory with the necessary communications protocols. These problems must be solved at low cost and high reliability before Internet-based SCADA can be implemented in industrial applications. The third is assurance of data protection and access control.

Embedded gateway

One solution to these problems is to connect the device to a PC and have the PC make the connection to the Internet via an Internet service provider using Secure Socket Layer. Unfortunately, this solution may not meet the low-cost criterion and, depending on configuration, can lack reliability.

An alternative to using a PC is an embedded solution: a small, rugged, low-cost device that provides connectivity capabilities of a PC at a lower cost and higher reliability. This device (sometimes referred to as an Internet gateway) is connected to the equipment via a serial port, communicates with the equipment in the required native protocol, and converts data to HTML or XML format. The gateway has an IP address and supports all or at least parts of the TCP/IP stack—typically at least HTTP, TCP/IP, UDP, and PPP. Once connected to the Internet, the gateway responds to an HTTP request with an HTML or XML file, just as if it were any PC server on the World Wide Web. In cases where the equipment incorporates an electronic controller, it may be possible to simply add Web-enabled functionality into the existing microcontroller.

Firewalls, encryption, passwords

The open nature of the Internet requires data security measures when implementing Internet-based SCADA systems. Processes, procedures, and tools must address availability, integrity, confidentiality, and protection against unauthorized users.

  • Availability: Redundant servers increase system up time. Firewall protection must be provided in the gateway and servers along with automated monitoring to detect DNS attacks.
  • Integrity: System must ensure encrypted data signatures, authentication to restrict access, and similar tools do not modify or corrupt data.
  • Confidentiality: System must ensure restricted access to data through encryption and to the system by employing authentication such as Secure Socket Layer.
  • Protection against unauthorized users: Multi-layered password protection must be provided at all levels in the system.

Other Issues

The open architecture of an Internet-based SCADA system combined with appropriate field equipment makes it possible to develop an integrated system. However, interoperability requires data format and transmission protocol standardization.

Preferred data format is XML, a meta-language that provides a facility to define tags and structure. The simpler alternative markup language, HTML, has undergone continuous development to support new tags and style sheets. However, these changes are limited by backward compatibility and to what browser vendors are willing to support.

Preferred data transmission protocol is HTTP (or HTTPS when security is required) because it is firewall friendly and allows Web servers to be used to control data transmission. The alternatives, TCP/IP or UDP, require the customer’s IT department to open ports on servers, introducing potential for cyber attack.

Scaling an Internet-based SCADA system from a few to thousands of assets while maintaining near real-time performance requires a system architecture that enables data to be pushed from the remote equipment without host system polls. This approach has been implemented in systems supporting simultaneous 20-second updates from 3,000 devices.

As the acronym implies, the purpose of a SCADA system is to allow asset owners and operators to monitor and control remote assets, therefore the presentation of data is a critical component of any SCADA system. Use of Internet protocols and services to collect data makes it simple to apply standard Web browsers for data presentation.

Technology chosen for development of the Web page user interface must support development of sites that are highly dynamic, incorporate animation, and provide a high level of usability. Standard Web page technologies such as HTML, JavaScript, and Macromedia Flash are ideal for the development of SCADA presentation pages.

Inside, outside, subscription

Implementation of an Internet-based SCADA system is a complex project that can be handled in three ways: the owner can purchase components and act as integrator or hire one; contract for a turnkey SCADA installation; or contract for turnkey subscription-based SCADA services.

With complex SCADA projects a single vendor can serve as system architect with total project responsibility.

Or, for a monthly fee, vendors can design the system, install field hardware if necessary, operate secure servers to host the data, and provide customers access to their data via a standard Web browser.

500% ROI

Use of Internet-based SCADA systems to monitor and control gas production wells has been proven to improve production and lower maintenance costs. For example, a field operator installed proprietary gas flow computers at nine wells to record flow data and store the data for collection once every 20 minutes via a SCADA subscription service.

The operator estimated that operational efficiencies achieved through use of the SCADA service resulted in production increases of 7% per year. The subscription service fee was $25 per month per well for a period of 36 months, and the cost of field automation equipment was $30,000. Using a discount rate of 10% and $1.50 per mcf gas price, the project return on investment was calculated to be in excess of 500%.
