Reviewing ANSI/ISA-101.01 HMI standard for process automation

Mike Lennon, P.E.

Michael A. Lennon, P.E., Operations Manager at Applied Control Engineering, presented an informative talk on upgrading HMI screens. He covered tackling upgrades of existing systems as well as new projects. The meeting, held at Rumsey in Conshohocken on January 18th, attracted about 20 attendees. Mike noted that his presentation overviews recommendations of ANSI/ISA-101.01 Human Machine Interfaces for Process Automation Systems, a standard published in 2015.

Mike said that when upgrading an existing system, often the current HMI:

o follows the P&ID graphic
o has no common guide for style
o assigns colors inconsistently
o shows no indications of trends to provide context.

Despite these shortcomings, management and operators may resist dramatic changes. The best approach is to implement change incrementally, concentrating on what works, colors, and navigation. It’s important to include input and buy-in by operators.

Mike said that the standard recommends primarily a gray screen where bright colors attract attention only to developing process problems. A bar of buttons at the bottom of the screen can be used to navigate to a new screen with details of an alarm condition. Graphics to avoid include gratuitous animation such as spinning motors, moving conveyors, and splashing liquids.

January 2017 Section Meeting
Topic: Upgrading the Human Machine Interface

This presentation focuses on upgrading existing HMI applications to use the concepts discussed in ISA101. It offers implementation strategies for controls engineers with existing system(s). Development of the upgraded HMI graphics may be taken in stages to allow for initial improvements to the system.

Speaker: Michael A. Lennon, P.E.,
Operations Manager, Applied Control Engineering, Inc. (ACE)

Mike’s professional experience has been primarily with batch processing, including the bulk/commodity chemical, specialty chemical, and pharmaceutical industries. He has also applied his control systems experience in electrical power generation, oil & gas, and food & beverage industries. Mike holds a Chemical Engineering degree from the University of Delaware and is currently the Vice President of the Delaware Association of Professional Engineers.

Pursuing the connected enterprise

Dave Kang, Industrial Networking Specialist at Rumsey Electric, spoke at our Novemember 2016 meeting, held at Ives Equipment in King of Prussia and attended by about 20. He noted early on that his background is primarily related to IT, which is dominated by standard Ethernet, protocols and cables. Industrial plants, on the other hand, often have proprietary networks, protocols, and cables. How do we connect the two?

The priorities of the two worlds differ. Plant operations key on network availability, integrity, and confidentiality, while in IT these priorities are reversed. Both want to protect against threats. The question is: what is a logical framework for finding ways to converge the two network worlds.

Challenges are numerous in the industrial plant settings. Examples include budget restraints, aging infrastructure and equipment, and a resistance to change. The scope of changes needed may seem overwhelming. Continue reading

November Section Meeting
Topic: The Connected Enterprise:
Design and Implementation

Ethernet on the plant floor has been around for a number of years, but in what manner has it been implemented as you see it? Is your plant and corporate network converged – and if so, is it being done so in an appropriate manner?

We will examine the reasoning behind why any manufacturing or process organization might be interested in network convergence and what benefits it will bring to all levels from plant floor to top level management.

Finally, we will take a bird’s eye view of the CPwE – Converged Plantwide Ethernet Design and Implementation Guide and how concepts of connecting the enterprise and the plant floor may prove to not only be beneficial but more and more of a requirement with the exponential growth of Ethernet and the IIoT.

September presentation: background on best practices for pH measurement

Jay Mershon, Analytical Business Manager for Endress+Hauser, provided a well received and informative presentation on pH measurement at the September 21 evening meeting of the Philadelphia ISA section. About 25 attended the meeting, held at Rumsey Electric in Conchohocken.

Mershon began by noting that making this measurement is often troublesome with many factors that can adversely affect accuracy. He said that the frequency of cleaning and calibrating probes (in that order) depends entirely on the specifics of an installation. Additionally the probes may have a lifetime of only six months–even less for high temperature installations. The response time of the measurement can degrade with conditions, making online control of pH difficult. The measurement is temperature dependent; compensation usually takes place in the transmitter.
