Adopted by many innovative industrial automation users worldwide, this platform-independent process management software sets the standard for Operational Excellence. Combining the latest web technology with exceptional quality has resulted in the most advanced SCADA solution yet – one that is designed to meet the latest engineering and maintenance requirements. Thirty years of project experience and innovation in the oil & gas, petrochemical, and power industries are the foundation for this next generation SCADA software.

This greatly enhanced version of the FAST/TOOLS web-based SCADA system enables a new and innovative approach to remote engineering and maintenance, deploying process applications and monitoring via web-based services. Its use of the latest technologies and web-based architecture provides management and maintenance personnel easy and secure access to their assets FAST/TOOLS has high-level system integration capabilities, facilitating ever more intuitive and advanced system deployment and significantly reducing costs.

Main Features

Web-based maintenance, engineering, and application deployment

Remote asset management drives down operating costs and optimizes the sharing and exchange of information. The latest web technologies are incorporated in the Java-based FAST/TOOLS engineering and maintenance environment to enable access and execution within standard web browsers like Internet Explorer and Firefox. This facilitates access by the various start-up and design teams to the application and system software configuration, in a zero deployment and transparent manner. The integrity and confidentiality of process information is preserved. Java was chosen as it can be used with standard web browsers; it is architecturally neutral and provides good support for superb graphics.

Numerous benefits are derived from this concept including global access and sharing of data via collaboration centers and other venues, allowing continuous application development and management to take place. Furthermore, a reduction in the number of required paper documents and the higher level of management efficiency made possible by the continuous availability of process information are expected to lead to a reduction in cycle time.

Secure deployment

A commitment to security policies that are in accordance with corporate IT directives is the foundation for our development activities that are targeted at achieving a secure deployment. To enhance security, this system and its applications are hardened to prevent failures and protect against unauthorized access and use. At the same time, thanks to a simple licensing policy, it is now easier than ever to reduce costs through web-based engineering and virtualization. A web-based server and client architecture ensures easy remote access and facilitates the deployment of security enhancements as well as graphics and application services.

Advanced engineering methods

The new engineering and visualization editor with an advanced sheet- and form-based environment allows for a conveniently arranged framework that tremendously reduces the amount of work required for engineering and visualization. The new and easy to work with environment combines the power of today's most sophisticated graphical applications in one easy to manage package. Dynamic layers and visibility groups enable multilevel processes and KPI monitoring and supervision within a single operations architecture.

Multi-language support

The new operator environment is language independent and can be triggered by login procedures and the like. This allows for a mix of local and remote operators, as appropriate, and is not limited by language barriers.

Integration capabilities

A comprehensive new plug-in structure that goes beyond “traditional driver configuration” allows for excellent integration of new and existing infrastructure, guaranteeing seamless vertical and horizontal integration. Capabilities such as soft-marshalling and the integration of FOUNDATION™ fieldbus device messages and information are setting the standard for Operational Excellence. This is both applicable for the Yokogawa product family as well as an extensive list of third-party hardware and software products. These include the Exaquantum Plant Information Management System, the STARDOM Network-based Control System, the DAQMASTER Data Acquisition Unit, the FA-M3 PLC, and the ProSafe-RS Safety Instrumented System.

Barcodes

You don’t need to be a rocket scientist to understand them; they are just a different way of encoding numbers and letters by using a combination of bars and spaces of varying widths. Think of them as another way of writing since they replace key-data entry as a method of gathering data. In business, the correct use of bar codes can reduce inefficiencies and improve a company’s productivity thereby growing their bottom line.  Optical Barcode Scanners

Simply put, barcodes are a fast, easy, and accurate way of entering data.

This may come as a surprise to you! A barcode doesn’t contain descriptive data. Just as your social security number doesn’t contain your name or address, a bar code is also a reference number that a computer uses to look up an associated record that contains descriptive data and other important information. 

Barcode Reading

Bar codes are read by sweeping a small spot of light across the printed bar code symbol. Your eyes only see a thin red line emitted from the laser scanner. But what’s happening is that the scanner’s light source is being absorbed by the dark bars and reflected by the light spaces. A device in the scanner takes the reflected light and converts it into an electrical signal.

The scanner’s laser (light source) starts to read the bar code at a white space (the quiet zone) before the first bar and continues passing by the last bar, ending in the white space which follows it. Because a bar code cannot be read if the sweep wanders outside the symbol area, bar heights are chosen to make it easy to keep the sweep within the bar code area. The longer the information to be coded, the longer the bar code needed. And as the length increases, so does the height of the bars and spaces to be read.

Barcode Scanners

There are three basic types of bar code scanners—fixed, portable batch, and portable wireless.

Fixed scanners (hand held or mounted) remain attached to their host computer or terminal, and transmit one data item at a time as the bar code is scanned.

Portable batch scanners are battery operated and store data in memory for later batch transfer to a host computer.

Wireless portable scanners also store data in memory, however data is transmitted to the host in real time. This allows for instant access to all data for management decisions. HHP Dolphin 9500 scanning pallettes

Barcode Symbologies

Bar codes come in many flavors. Most of us are familiar with the ones seen in grocery or retail stores, but there are many others that are used as standards in various industries. Healthcare, manufacturing, retail, etc. all have symbologies unique to their industry and aren’t interchangeable. Why are there so many different types of bar codes? Simply because different symbologies evolved to solve specific problems. Let’s take a quick look at a few of the most common symbologies*, and how, where, and why they’re used:

UPC/EAN - This is the symbol used on items destined for the check-out line. UPC symbols are fixed length, are mandatory in the retail and food industry, and not used anywhere else for the most part. They were developed to meet the needs of grocery retailing as it fits 12 digits into a reasonably compact space.



Code 39 - Developed because some industries needed to encode the alphabet as well as numbers into a bar code, Code 39 is by far the most popular bar code symbology of choice. It is typically the non-food standard bar code, and is used for ID, inventory, and tracking purposes in various industries such as manufacturing. However, Code 39 produces relatively long bar codes and may not be suitable if label length is a consideration.

Code 128 - This bar code came about when the need for a wider selection of characters arose than Code 39 could provide. When label length is a consideration, Code 128 is a good alternative because it’s very compact and results in a dense symbol. This symbology is often used in the shipping industry where label size is an issue.

Interleaved 2 of 5 - Another popular symbology in the shipping industry, Interleaved 2 of 5 is widely used by the warehousing industry, too. This is also a very compact symbology and you’ll see them on the corrugated boxes in which things are shipped to the grocery store.


Postnet - Unique to the United States Postal Service, this symbology encodes zip codes for processing mail for speedy delivery.

PDF417 - Known as a 2D (two-dimensional) bar code, this is a high-density, non-linear symbology that reminds you of a crossword puzzle. But the difference between this and the other bar codes listed above is that PDF417 is really a portable data file (PDF) as opposed to simply being a reference number. Some states require a 2D bar code be printed your driver’s license. If your state has this requirement, it’s interesting to know that there’s room enough in this bar code to encode your name, photo and summary of your driving record, and other pertinent information. As a matter of fact, a PDF417 bar code can encode the Gettysburg Address in a space the size of a postage stamp!

An important fact to remember is that the larger the width of the bars and spaces, the more space it takes to print the bar code; therefore, the lower the bar code density. The thinner the bars and spaces, the less space is required and the higher the bar code density.

To the left, you'll see pictured Banner Engineering's new line of Optical Bar Code Readers.  Capable of reading normal bar code labels as well as 2D labels (at any angle), these readers are state of the art in quality and bare special mention here because they significantly lower the price to quality ratio.

Barcode Scanners

A basic bar code scanner consists of a scanner, a decoder, and a cable that interfaces between the decoder to the computer or terminal. The scanner’s function is to scan the bar code symbol and provide an electrical output to the computer that corresponds to the bars and spaces of the bar code. However, it’s the decoder that recognizes the barcode symbology, analyzes the content of the bar code scanned, and transmits that data to the computer in a traditional data format. A scanner can either have the decoder built into its handle or be “un-decoded” which requires a separate box, called an interface or wedge. Un-decoded scanners are also used when connecting to portable batch terminals as the decoding is performed by the terminal itself.

Fixed Scanners

Keyboard Wedge Readers.  A keyboard wedge reader is attached to a computer through a port called the keyboard interface. When a bar code is scanned, the information is transmitted as though it were keyed in from the keyboard. Sometimes they’re referred to as wedge readers because they physically wedge between the keyboard and the computer and attach as a second keyboard. One great advantage of a keyboard wedge is that bar code reading can be added with no software changes necessary; the software thinks that the data received was entered by a speedy typist. With a wedge reader, any program that accepts keyed data will accept bar code data with no change.

Serial Bar Code Scanners.  Another way to transmit data from a bar code reader to a computer is to connect it to the computer’s RS-232 serial port. The bar code information read will be transmitted in ASCII format and look just like keyed data to the computer. Using a serial port connection is ideal for a multi-user computer. With serial ASCII terminals for each user, the bar code reader can attach between the terminal and host computer and transmit ASCII data just like the terminal.  To the left, see pictured a barcode print and apply application.  The barcode is printed, then verified by a reader, then the pallet is rotated and the same barcode is printed and read on the other side.

Portable Batch Barcode Scanners

Portable batch scanners are hand-held battery operated readers which store data in memory for uploading to the host at a different time. A portable batch reader contains a bar code scanner, an LCD-display to prompt the user to perform a task, and a keyboard to enter variable data such as quantities. A cradle must also be purchased to upload information to the computer. Portable batch scanners are ideal when mobility is a must and when collected data isn’t immediately needed. These scanners come in a variety of styles including hand-held, wearable and truck mounted. Your application will determine which style is best.

Wireless Portable Barcode Scanners

When you need to collect information at a remote location, and need the information immediately, a wireless solution is the perfect one. A wireless scanner is also built into a terminal, and uploads data to the host as it’s scanned, instantly and accurately. Wireless products let the user scan the information at the point of activity which makes it ideal for many industries.

Who is the control system expert – customer or manufacturer?

With modern systems having so much functionality and requiring specialist knowledge David Clough, UK sales manager of Yokogawa, asks who is the expert these days? The customer knows what he wants to achieve but maybe not the most efficient way.

Today, control systems are so feature rich it is almost impossible to make use of all the functionality available. The challenge then is how to make the most of a modern system and obtain maximum benefit without spending significant amounts of time and cost evaluating and potentially configuring every feature embedded in the system.

Often the basic purpose of a system is compromised by the desire to use the “free features” to best advantage. Once the system is designed, installed and commissioning is under way, one of the fundamental requirements is to tune the control loops to provide stable and reliable control of the process variables. Often this proves a challenge without the use of additional tools to speed up the optimisation of the PID settings, however if this is not implemented well the overall process performance will certainly be compromised. The multiple alarm and event choices for control loops and monitoring points then must be configured to provide a realistic level of operator alerts consistent with safe operation of the process. The alarm and event philosophy determined by the designer is critical to ensuring the appropriate level of alarms, as well as their priorities, are published to the operators under all circumstances. Too many alarms are just as dangerous as too few. We then should consider trends, graphic display design, reports, operator logs, historian, advanced applications – the list goes on.

No surprise then that the organisation best positioned to advise and help configure the system to meet the user’s needs should be the manufacturer of the system, after all the manufacturer designed the product to solve these problems. It is a fact that a system supplier will engineer and supply more systems than a user will ever buy – so who is the expert? I propose the customer should define what he wants from a system and the manufacturer should design, engineer and provide the system to meet the agreed definition – we could argue the expertise is slightly different but ideally collaborative.

Services to provide the important commissioning and configuration of the operational system are often squeezed into the last period of the project when time is short and pressure to become operational is at its strongest. Little wonder then that the system basics are not always left in an ideal state at project handover and significant scope for improvement is available. This usually leaves the operational team with the challenge and the need for expertise from the manufacturer is at its greatest. Fortunately this need is recognised and has led to a comprehensive set of services and capabilities available from the systems suppliers to be able to deal with this requirement. This need also continues over time as process modifications are made then resultant system modifications require to be implemented, loops re-tuned etc.

If you combine this with the requirement to support an operational system, routine maintenance tasks, updates and upgrades, system health monitoring and diagnostic fault management, the challenge should not be underestimated.

With many manufacturing plants reducing headcount in the drive for economic improvement and resultant expertise being lost it is even more important to ensure your system supplier has the capability and expertise to provide you with the necessary support you require to maintain a high performing, safe and reliable system controlling your process. The successful integration of these services into the operational philosophy of the facility is becoming more and more cost effective for customers due to the high cost of training people, required equipment and spares associated with every unique system installed.

So who is the system expert – customer or manufacturer, I leave you to decide?

Bridging Profibus and Modbus-TCP networks with an Anybus X-gateway

Simple to use intelligent Gateway connects Schneider Electric, ABB or GE PLC’s with Siemens automation systems and networks.

The Anybus X-gateway from HMS Industrial Networks enables system integrators to easily transfer I/O data between two different PLC systems and networks. The X-gateway is a configurable stand-alone gateway that allows plant-floor devices on a Profibus network to communicate with the devices on a Modbus-TCP network and vice versa. Typical applications are installations with mixed usage of Siemens and Schneider Electric, ABB or GE PLCs. One example is automobile manufacturing plants where Profibus based segments shall be integrated into industrial Ethernet based control applications with the popular Modbus-TCP protocol.

The X-gateway is a compact device for standard DIN rail mounting and 24 Volt industrial power supply. It functions as a server (slave) on the Modbus-TCP network and as a master on the Profibus side. The Profibus master functionality is configured with HMS´ Anybus NetTool for Profibus, a powerful but easy to use Windows-based configuration tool which comes free with the X-gateway. After the initial configuration has been downloaded into the X-gateway, it passes up to 512 byte of input and 512 byte of output data transparently between Modbus-TCP and Profibus. Up to 124 Profibus slaves can be connected to the gateway. In addition to its data transfer capabilities, the X-gateway incorporates a powerful embedded web server on the Modbus-TCP side which supports web based remote diagnostics and visualization. Even an OPC server is included in the scope of delivery of the X-gateway. The X-gateway contains Profibus and Modbus-TCP communication interfaces that have been certified for full compliance to the respective protocol standards.

The Anybus X-gateway family is a product line consisting of over 200 proven, robust and ready-to-use gateways aimed to connect almost every possible combination of two industrial networks. The product family supports 17 different fieldbus and industrial Ethernet networks such as Profibus, DeviceNet, CANopen, CC-Link, EtherNet/IP, Profinet and many more. All versions work the same way and provide a flexible standard solution to connect two industrial networks.
