Fieldbus Software Tools

Ethernet is now established as the preferred network for business and control layers in industry. In factory automation and the power industry it is established as the device level network of choice. In process automation it is becoming established for high bandwidth applications such as cameras and analysers and is forecast to be adopted at device level.

The deployment of Ethernet into process automation has been hindered by the gas or dust hazardous area classification in which the end device is often installed. The high installation costs of the mechanical protection methods required to install general purpose Ethernet in hazardous areas, together with the maintenance limitations, have reduced the uptake of both wired and wireless Ethernet. Many end users prefer to use intrinsic safety for low power hazardous area applications, such as instrumentation, having made significant investment in training their design, installation and maintenance staff in the technology.

IS Ethernet has been adopted for communications across hazardous areas using copper for short distances and fibre for long distances. It provides WLAN infrastructure for the mobile operator using Intrinsically Safe mobile computers and tablet PCs, reducing installed cost and simplifying architecture with IS serial devices and providing automation infrastructure in coal mines. High definition intrinsically safe Ethernet cameras have been widely adopted in mining and process applications, allowing operators to monitor critical systems from a safe environment

Ammonia, NH₃, is an anhydrous compound of nitrogen and hydrogen. By using an Ammonia Dissociator, the anhydrous ammonia can be separated or “cracked” into its constituent components of Nitrogen and Hydrogen, thus providing a cost effective way to generate hydrogen.

When ammonia dissociates it does so according to the following chemical equation: 2NH₃ → N₂ + 3H₂

Hydrogen, ammonia and nitrogen will be present in precise proportions depending on the degree of dissociation and so it is important to measure the percentage dissociation of ammonia for process control and optimisation.

Hydrogen has a significantly different thermal conductivity to ammonia and nitrogen, which means that a measurement of the mixture’s thermal conductivity allows the amount of hydrogen and hence the amount of ammonia to be calculated.

The MTL katharometer based thermal conductivity analysers are ideal for making measurements of these mixtures and can be configured to provide output of % Hydrogen, % Ammonia or % Dissociation.

Gaseous nitrogen has a wide variety of industrial applications and more nitrogen is used industrially than any other gas. Nitrogen is commonly thought of as an inert gas and it is the non-reactive properties of nitrogen that make it so highly valued especially for gas blanketing applications. Nitrogen is also used in a broad range of industries, including chemi-pharma and oil and gas to metal refining and fabrication processes.

However, nitrogen is a difficult and expensive gas to measure. Therefore, an alternative solution is to measure the level of impurities, which is an accepted method for measurement of N2 purity. The MTL katharometer (thermal conductivity) range of analysers are ideal for measuring the amount of N2 present in binary or pseudo-binary gas mixtures, whilst our range of galvanic (G range) or zirconia (Z range) oxygen analysers are well suited to measure residual oxygen for nitrogen purity applications

Our MTL5500 range of Intrinsically safe isolators, now have UL Approval, are UL labelled and are in stock. All available models numbers are listed below.

The MTL5500 range modules are versatile yet simple to apply; use the latest technology and yet are well proven.

These contrasting attributes stem from the progression of our expertise in the design and manufacture of isolators for intrinsic safety and the application of innovative technology to achieve the required separation and segregation of the circuits.

The MTL5500 (DIN-rail mounting) and MTL4500 (backplane mounting) isolators share a common design, differing only in the mechanical mounting and connection methods.

• Compact modular design with DIN rail mounting
• High packing density
• Single and multi-channel I/O modules
• 3-port isolation with low power dissipation
• Compatible with MTL5000

Supervisory Control and Data Acquisition (SCADA) and industrial control systems have long been considered immune to the cyber-attacks suffered by corporate information systems. The move to open standards such as Ethernet TCP/IP and web technologies has seen control systems affected by a growing number of both malicious and non-malicious network security events impacting critical infrastructure and manufacturing industries.You may never be attacked by a serious hacker, but typical control networks are extremely vulnerable to simple day to day security and reliability issues. Human errors, poor network segmentation and unprotected points of entry into the network, ‘soft’ targets such as un-patched PCs and vulnerable PLCs, can result in significant production losses and even safety issues.

Traditional firewalls are too complex for most security professionals to configure correctly and are even harder to set up properly on the plant floor. Control devices and protocols offer limited authentication, integrity or confidentiality mechanisms and can be completely controlled by any individual that can “ping” the device. Nor can they be easily patched or have security features added to them even when security vulnerabilities are discovered.

The MTL Tofino™ Industrial Security Solution is much more than just a firewall. It has revolutionised the approach of control system cybersecurity by introducing ‘Enforcer modules’ for popular Industrial Control System protocols in IEC 62443 ‘Zones’ and ‘Conduits’, providing a ‘defence in depth’ architecture. The system changed the way industrial ethernet security is managed by providing an intrinsically secure solution right out of the box. This provides a simple, effective cybersecurity solution for control and automation engineers which does not require IT skills for configuration and installation. The Tofino Configurator (TC) platform will configure, monitor and manage the functions of each remote Tofino™ Appliance so that it can be automatically tuned to meet the security needs of the devices it is protecting.

The 9202-ETS is our new second generation Tofino™ solution that continues to provide the highest level of network security with the great benefits of its predecessor with added features for further customer value. It is exceptionally easy to install compared with alternative systems and includes the latest configurator software to protect industrial networks from cyber-security vulnerabilities. This maximises plant uptime and process availability while protecting it from a network attack.

The MTL Tofino™ security solution is a package consisting of the 9202-ETS MTL Tofino security appliance hardware, 9211-TC Tofino Configurator (TC) and any additional Loadable Security Modules (LSMs) if required. Select the 9202-ETS icon below for more information.

This latest solution is backwards compatible with its predecessor the 9211-ET and the CMP software. As part of the second generation release a migration path has been developed to support our existing installed base. Please contact our technical support team for more information.

With process plants now spread over wide areas and the demand for more information, the transfer of electrical signals present many challenges. High power devices mixed in with low level signal transfer generates an environment which has an adverse effect on the ability to control and measure the processes.

Signal conditioning makes a major contribution to resolving issues such as varying grounding potentials, reducing signal noise and eliminating earth loops. It also protects sensitive control equipment from dangerous voltages. All these benefits add up to reduced down time, fewer failures, greater product yield and significant cost savings.

By using signal TI multiplexing in process systems, the cost of installed wiring can be reduced by up to 50%. Further savings are achieved by reducing the number of inputs to the host, cabinet space and weight.

In Functional Safety, applying the generic standard IEC 61508 or the process industry sector standard IEC 61511…

The Safety Integrity Level (SIL) is essentially a measure of the probability for the availability of a Safety Instrumented Function (SIF) to take a process to a safe state upon demand.

The SIL applies to the whole SIF rather than to an individual element.

To achieve the required availability of a SIF then multiple parallel or redundant instrument loops are often needed, with voting in the ‘logic solver’ to resolve the status. Thus the SIF, or parts of the SIF, may be structured as 1oo1 (One out of One), 1oo2, 2oo3, etc to achieve the requisite low probability of failure.

This also follows from the need to follow IEC 61511 requirements for hardware fault tolerance, such as…

Our range of IS displays come in both panel and field mounting options. In addition to the user configurable loop powered indicators, are ‘mini HMI’ text and graphics that displays that provide operator input and control via a host computer.

The MTL4840 and MTL4850 HART multiplexers do not provide a safety function but are frequently applied alongside safety shutdown systems with connection to the analogue loops. In practical terms the concern for the multiplexer is that by making a connection to the safety loops there must not be an adverse effect on the analogue values that are being monitored and controlled by the safety system.
For the MTL4840 the non-interference by the multiplexer is affirmed in the certificate issued by Baseefa: BAS01SP9449X.pdf
Similar documents for the MTL4850 multiplexer are in preparation and will be listed here soon.

To design, implement and prove the operation of functional safety loops, the engineer should refer to the information contained in the individual Safety Manuals for all of the elements that are providing a safety function. In some instances just the hardware failure rates of the components may be required for comparison and calculation; this information is contained in the Data Declaration.

Zener Barriers are normally considered as wiring connection equipment in the safety loops – they are passive coupling devices which in this context do not provide a safety function other than their hazardous area intrinsic safety protection. Below are links to documents which will be of assistance to an engineer looking to compile the safety case analysis:
AN9036.pdf ~ Application Note that provides an introduction to Functional Safety and IEC 61508.
Fsafebar.pdf ~ Discussion of use of zener barriers in safety loops.

MTL isolating interfaces are alternatives to shunt-diode safety barriers for protecting electrical circuits in hazardous areas.

They need no high-integrity earth and provide extra features such as signal amplification and relay functions. The isolation of hazardous- and safe-area circuits allows each to be earthed at any convenient point, simplifying installation and avoiding earthloop problems.

MTL offers the best choice in DIN-rail and backplane mounting isolators to meet the requirements of modern control interfacing systems. The DIN-rail mounting isolator ranges provide a wide choice of functions with high accuracy and reliability, while the backplane mounting products are established as the leading IS system interface with solutions for all the major DCS companies.

The MTL4500 range is the latest generation of backplane mounting products, building upon the heritage of MTL4000 and introducing many key application benefits. The MTL5500 range launches a new industry standard for DIN rail mounting products, ideally suited to a wide variety of interface tasks for process instrumentation, complemented by the well proven MTL5000 range.

In most applications MTL4500 modules can directly replace MTL4000 models but check with MTL if you have any concerns. Similarly, MTL5500 supplants MTL5000 range as the DIN rail interface family of choice. With this mounting arrangement, it is practical for models from both families to be used alongside each other during the transition phase from the old range to the new.

The following table shows the wide range of approvals and certificates that apply to the MTL4500 and MTL5500 ranges:-

Note: there are many other local country or industry approvals for the products such as from Australia, Brazil, India, China, Russia, Japan, Korea, for example. For product certificates click here.

APPLICATIONS SUPPORT

MTL has individually earned a reputation for the highest levels of pre- and postsales support. Trained local and regional sales and applications engineers are available to provide technical advice at every stage of the design cycle, to ensure trouble-free start up and rapid diagnosis of in-service problems. Engineering-led management is at the heart of MTL’s strategy for fieldbus success.

DIAGNOSTIC EXPERIENCE

MTL has extensive experience of diagnosing faults on fieldbus networks, and has established a technical lead in the manufacture and use of hand-held test equipment. Building on this experience MTL have released the first Fieldbus Foundation^TM registered diagnostic module. This easily integrates diagnostics information into your choice of fieldbus control system with integrated help screens to assist with the rapid tracing and rectification of field faults.

CONTINUOUS PRODUCT DEVELOPMENT

An ambitious programme of product development demonstrates MTL’s commitment to remaining a foremost supplier of components to the fieldbus community. With the regular introduction of innovative new products, MTL aims to satisfy the requirements of this and future generations of fieldbus users.

GLOBAL HAZARDOUS-AREA APPROVALS

With over 30 years of experience in designing explosion-protected equipment for the process industries, MTL know how to achieve utmost safety for fieldbus installations in hazardous areas. MTL’s established fieldbus component ranges carry comprehensive approvals to satisfy installation requirements world-wide, and all new products are subject to a rigorous certification programme.

FF-831 APPROVAL

All MTL fieldbus power supplies are qualified by the Fieldbus Foundation^TM to the FF-831 standard, which is the guarantee of reliability and performance.

CONTROL SYSTEM VENDOR APPROVAL

MTL fieldbus power supplies and wiring components have been tested and approved by all the major fieldbus control system vendors. This endorsement of MTL’s quality and reliability means that end users can choose fieldbus products with confidence.

Two different approaches are taken to installing instrumentation in hazardous areas.

• Using instrinsic safety or non-incendive field wiring - no gas clearance needed for live working
  

• Using flameproof/explosionproof or non-arcing - requires gas clearance for live working

As end users have invested heavily in design, installation and maintenance of instrumentation based on their selected hazardous area protection methods, it is recommended that they use the same methods or site standards for the fieldbus network as they use for conventional instrumentation.

Two technically different approaches have emerged for interconnecting intrinsically safe and non-incendive fieldbus instruments:

• Energy Limited Trunk networks - where fieldbus trunk and spurs are live workable

• High Energy Trunk networks - where only the spurs are live workable

Finally, for flameproof/explosionproof or non-arcing instruments there is:

• High Energy Trunk networks - with no live working
  

We are no newcomers to the fieldbus environment. From involvement in defining the earliest standards through to representation on today’s industry bodies, Eaton and Relcom have attained a distinguished profile in fieldbus technology. And to maximise your efficiencies using our equipment we have produced various software packages designed to help fieldbus engineering.
