Smart transmitters have increased accuracy an order of magnitude or more, and drift is so slow that calibration intervals can be significantly extended. However, a measurement is only as good as its installation. Not enough knowledge is published or presented on how to make sure the installation doesn’t limit performance or create maintenance and reliability issues. Here, Hunter Vegas and I (cofounders of the ISA Mentor Program) offer what we think is important.
The newest resource to our ISA Mentor Program, Daniel Warren, has stepped up to. This concept eases troubleshooting, CV-MV pairing, developing models and more Often, chemical process control is fundamentally inventory control. Understanding the cause-and-effect of the inventory is key to understanding the process, troubleshooting, choosing appropriate controlled variable-measured variable (CV-MV) pairing, designing cascade or ratio structures, specifying safety overrides and developing models (either first-principles or empirical).Usually, we don’t measure the inventory. We measure the response to it. Unfortunately, an initial focus on the response often distracts the person from seeing the fundamentals. Recognize the fundamental mechanism.

Emerson's Rosemount continues to embrace digital technology to deliver reliability, accuracy The first applications of any new technology often do little to capitalize on its potentially transformative capabilities. Rather, new technology is first used to replicate its predecessor’s functionality—only afterwards do new possibilities begin to emerge. Such was the case with the earliest analog electronic pressure transmitters. An analog milliamp or low voltage circuit replaced the pneumatic signal, but the force-balance sensor mechanism of the previous generation pneumatic transmitter remained—complete with its drift-prone and maintenance-intensive moving parts.Only when the entire sensor and communications package was re-imagined from the ground up in 1969 did Rosemount Engineering Co. Have the complete package of.
Meggitt's PCH420V vibration sensor has a programmable transmitter that allows vibration data to be accessed by HART enabled process controllers. Meggitt's PCH420V is the first HART®-enabled piezo-electric vibration sensor enabling continuous online monitoring of balance-of-plant assets with a digital connection to PLC or DCS systems for local analysis of multiple vibration bands. They are capable of installation in multi-drop configurations and reduce wiring requirements. HART functionality enables the user to specify vibration frequency bands, detector types and full-scale measurement ranges—effectively enabling field-configuration for specific monitoring requirements. PCH420 sensors are powered by the network for continuous coverage, unlike wireless solutions only offering snapshots of asset performance and employing batteries that require frequent replacement.

This effort involves many elements; much hinges on the condition and performance of process equipment. Getting a handle on relevant metrics requires effective instrumentation and data analytics — which often can pose challenges due to a lack of measurement points and the complexity of data analysis software.Wireless instruments can provide a more cost-effective and easy-to-install solution to provide efficient data streams. Of course, you must always balance the cost of WirelessHART instruments and the possible downtime from installing them against expected benefits. Presuming you can justify installing WirelessHART instruments, you certainly. Monitoring versus controlling has a significant impact on system design Flow measurement techniques continue to grow and evolve with new methods such as multipath ultrasonic, magnetic and Coriolis increasing at the expense of more traditional technologies such as orifice, weir and other differential pressure (DP)-based techniques.
The increased use of these new technologies is partly a result of the increased capability of microprocessors and sensors to enable measurements not possible without enhancements in these areas. Another reason for their adoption is that, in most cases, they also provide higher accuracy and rangeability than DP technologies.
But most of these flow measurement techniques tend to require more energy than DP flowmeters, and hence aren't well suited for deployment as wireless devices.A. D3v16 delivered with the new PCM5 process controller What's the best way to upgrade distributed control system software? Give it a new controller to run on. Obvious, really. However, this is still a rare event, sort of like two holes-in-one in a single round of golf or winning two prizes in one raffle.Still, that's exactly what NovaTech has pulled off with the July launch of its D/3 distributed control software, Version 16 (D3v16), which adds high-value, standardized features its users have sought to give them a competitive advantage. Not stopping at one major release, the company is multiplying D3v16's impact by delivering it with the new Process Control Module 5 (PCM5) process controller with embedded cybersecurity, full system virtualization down to the controller, and many ease-of-use. Compact controller unifies PLC, RTU and edge control, intrinsic cybersecurity, and universal I/O Just as all roads led to Rome, most if not all cornerstone functions of process control have been melding into more unified, multi-role devices.
One of the leading expressions of this coalescence is Bedrock Automation's new Open Secure Automation (OSA) Remote high-performance controller, which combines PLC, RTU and edge control, universal I/O and intrinsic cybersecurity into a compact, rugged, standalone module that's ideal for remote monitoring and control. Two models will be available: OSA Remote R10 with 10 soft-selectable channels and OSA Remote R20 with 20 soft-selectable channels.
OSA Remote also features free IEC 61131-3 engineering software, wide operating temperature range (-40 °C to 80 C°), all-metal enclosure, and pricing. We need to get a grip on AI while there’s still time We control the planet, not because humans are the strongest, fastest or biggest creatures, but because—as of yet—we’re the smartest of all God's creations.
The totality of our mental processes allowed us to best adapt to our environment. This was the case since the end of the last ice age, but it is ending because of our own activity. This ending does not endanger nature, but could endanger us. This new chapter in our evolution was opened by automation, which delegated some of our muscle and brain functions to machines.Human or 'normal intelligence' is the totality of all mental process to acquire and apply knowledge. When we delegate some of that intelligence to machines, they acquire artificial intelligence (AI).
The largest potential for electric motor energy savings lies in system- and process-level optimization Early electric motors were operated at one speed, guided by available current and voltage and often drive belt and pulley systems that mechanically controlled system speed and power. As motors evolved, efficiency improved, mostly by changing output control from mechanical to electrical and eventually leading to the creation of modern adjustable speed drives (AC drives). Today, the largest potential for electric motor energy savings lies in system- and process-level optimization. Many different measures can be taken to improve the performance of processes and systems, but AC drives have the most important role to play. System-level optimization is possible thanks to several key elements in AC drive technology: Motor independence: Drives. When they can be applied, digital positioners offer the opportunity to examine and optimize the “innermost” control loop The level simply wouldn’t stop cycling.
Maintaining a reasonably stable level in the small vaporizer—to feed a gaseous hydrocarbon feed to a catalytic reactor—was crucial to reliable operation, as liquid carryover to the reactor would cause a shutdown. But no matter how much the tuning constants were increased or decreased, the cycling wouldn’t stop.Loop tuning practices vary widely, from making the best of default values that haven’t changed since commissioning, to highly sophisticated, online model-based adaptive control. Despite its potential to reduce variability, increase operator confidence, and maximize rates and profitability, tuning control loops can be painfully random, sometimes relegated to individuals whose training.

Designing the best HMI requires the right knowledge Industrial human-machine interface (HMI) has been a lively topic of discussion and development for decades. The Abnormal Situation Management (ASM) style started in the 1990s with the ASM Consortium. ASM style evolved, and the best-practice HMI gained a series of names, including different spellings of “high“ performance, etc. Many names were trademarked by different parties, including ASM style.The ANSI/ISA-101.01, Human Machine Interfaces for Process Automation Systems standard was published in 2015.
Its most significant contributions were the introduction of a lifecycle to manage the entire HMI, and a common set of terms and definitions for HMI components.As standards and guidelines developed, technology evolved and open systems. Control's monthly guide brings you invaluable industry information to stay up to date on the latest trends and developments. Practical approach, benefitsThis online article, 'Improve alarm management,' by G.C. Shah of the Wood Group in Chemical Processing, covers how the main standards—ISA-18.2 (IEC 62682) and EEMUA-191, API RP 1167—provide guidelines for implementing an effective AM system by considering the alarm lifecycle. It also describes gap analysis and alarm system development. Read the article here.

Build essential capabilities into projects from the start As the number of intelligent devices able to communicate digitally continues to increase, which is a precursor and requirement of the Industrial Internet of Things (IIoT), one of the challenges is managing all the resulting data. Managing the data and associated flows, being sure it's captured and sent to the right place, is only one part of the challenge. Identifying and processing the data, so it becomes usable information on which actions can be taken, is why it's collected in the first place.For reference, the ISO definition of data is “sampled measurements of a physical quantity” (ISO 2041:2009). ISO defines information as “facts, concepts or instructions” (ISO/TS 13399-4:2014) or, per ISO-9000:2015, meaningful data.Without a. How to deal with the constraints of putting access points in hazardous areas In an ideal world, it wouldn’t be necessary to worry about explosive atmospheres.
Unfortunately, plant environments are far from ideal, with most process plants being about 80% Class I, Div. 2 (Zone 2) and another 10% Class I Div. 1 (Zone 1), so some protection is the norm. This is one constraint faced by network designers.If we could install all the required wireless network access points in unclassified areas, things would continue to be easy.
Unfortunately, this isn’t the case, and we need to place access points anywhere they’re required—unless, of course, we wish to spend significant effort with corresponding impact to system complexity by forcing the design to fit the area classifications. This is constraint two.Consistent. Our next group of common fieldbus errors center around diagnostics and alerts. The operations team had asked about a loop that appeared to be unstable, but by engaging the DCS autotune function, the systems engineer discovered issues maintaining a connection to the PID block.
Drilling down into the DCS diagnostics application, she noticed that the controller’s backup (standby) redundant partner was unavailable. It was alive, but cycling through successive unresolved downloads, never returning to a healthy state and confirming its availability as a hot backup. Had it not been for the loop troubleshooting, this condition might have gone unnoticed until the primary failed and no partner was available. That would not have been a good day. But the redundancy trouble indication was masked by standing “bad quality”.

Marshalling system supports configurable I/O The introduction of configurable I/O has given users a new world of opportunity and advantages.
With this evolution though, there remain traditional requirements and challenges like safely marshalling signals, converting voltages and simplifying loop checks.“The Honeywell Universal I/O solution is fantastic because it’s software- rather than hardware-based, so people who want to can keep their marshalling,” says Michael Hardman, product specialist, Phoenix Contact. But traditional marshalling requires I/O-specific components for each point, such as relays, fuses and isolators, which traditionally must be individually wired.' Phoenix Contact’s new VIP-ER system allows users to configure the wiring functionality for any type of. Senam aerobik indonesia.

Grandfathered systems now require a formal determination of adequacy ISA accepted the 2nd edition of IEC 61511, “Functional Safety — Safety Instrumented Systems for the Process Industry Sector,” as the replacement for the current U.S. National standard, ANSI/ISA 84. Unlike the previous edition, the latest U.S.
And international versions don’t differ at all. However, the “grandfather clause' now appears in clause 5, serving as a reminder that leaving an SIS “as is” demands a formal determination that it is achieving functional and safety integrity requirements, which must be determined by an assessment of the design, maintenance, inspection, testing and operating records for the installed system.Our sister website Chemical Processing examines some IEC 61511 requirements that.

The new liaison agreement specifically pertains to The Open Group Open Process Automation Forum (OPAF), which is focused on developing a standards-based, open, secure, interoperable process control.
It's easy to make small and costly mistakes when specifying and applying enclosures Every component of a control system, from sensors to cables to controllers, needs to be protected from its environment. The most common way of providing this protection is by placing the equipment in some form of enclosure. Sensors and associated electronics are typically packaged in a metal transmitter housing.
Cables have insulation, of course, and in many cases, the additional protection of conduit or a cable tray. Controllers and other larger electronics or combinations of equipment are normally mounted in some form of cabinet. The most common form of enclosure is metal, typically painted steel with stainless steel closing mechanisms and a suitable gasket or sealing assembly to provide the necessary level of protection from ambient.

'Ask the Experts' is moderated by, automation and safety consultant, who is also the editor of the Instrument and Automation Engineers' Handbook (IAEH). If you would like to become a contributing author of the 5th edition, or if you have an automation-related question for this column, write to Q: I am looking for information on loop drawings for smart instruments and sample drawings. If you could point me in the right direction it would be appreciated.
Paul Bulmer A: Loop drawings for 'smart instruments' are the same as for analog loops, except for the communication links between the components (Figure 1). The loop component symbols are given in ANSI/ISA5.1 (2009). As to the need for loop diagrams, there is disagreement. In the view of American engineering design firms, loop drawings are not really necessary (are a luxury) because if the P&ID flow sheets are sufficiently detailed, then the information that the loop drawings provide can be obtained from the instrument index, specifications, I/O lists and wiring diagrams, piping diagrams, logics, cable schedules, etc. This view has evolved because the main goal of these firms is to minimize the number of man-hour-consuming documents, and thereby gain a competitive edge by tightening budgets through limiting engineering costs.
