IIoT and Device-Level Network Design

Emerson's Dan Carlson


Wireless instrumentation has been available for manufacturers for more than a decade. Sensors have expanded beyond traditional measurements such as pressure, temperature, level and flow to measurements such as acoustic, vibration, conductivity and more. These easily installed Industrial Internet of Things (IIoT)-based field devices make more than monitoring and control possible—they make real-time personnel safety, reliability, energy efficiency improvements possible to help deliver greater performance.

Control Engineering: Bring IIoT capabilities to refineries and process plantsIn a Control Engineering article, Bring IIoT capabilities to refineries and process plants, Emerson’s Dan Carlson highlights considerations for building a solid foundation with device-level networking best practices.

Dan opens highlighting the capital expenditure side benefits of wireless instrumentation:

WirelessHART deployments reduce instrumentation installation costs by eliminating expensive cabling. The cost of adding a wired instrument in a refinery can range anywhere from $5,000 to $50,000.

He describes the global IEC 62591 WirelessHART standard.

This wireless protocol is based on the traditional 4-20 mA wired HART protocol. It leverages existing instrumentation practices for deploying and maintaining instrumentation, but without the traditional cost of running signal wires and supporting infrastructure, including junction boxes, cable trays, marshalling cabinets, and others.

A key component in this network architecture is the gateway. It:

Knowledge Sharing with ISA Mentor Program

Gregory K. McMillan


I’m lucky enough to be on the email distribution list for the ISA Mentor Program where automation hall of fame legend, Greg McMillan, shares some of the work he continues to offer well into his golden years. Greg and Hunter Vegas started this program in 2011 with the intent to transfer knowledge between seasoned automation veterans and engineers newer in their careers.

I bring all this up because there was a great question asked by one of the program’s protégés/protégées. In the blog post, How to Improve Loop Performance for Dead Time Dominant Systems, Greg wrote:

More Sustainable Food and Beverage Production

Emerson's Melissa Stiegler


More sustainable manufacturing means different things for different industries. For many food & beverage manufacturers, achieving more sustainable production means reducing water usage, waste, and carbon emissions.

Emerson’s Melissa Stiegler shared three ways technology has helped play a role in improved sustainability for food & beverage producers.

These ways include more efficient clean-in-place (CIP) operations, real-time mass balance calculations, and energy optimization.

Efficient Clean-in-Place

Biopharmaceutical Single Use Measurement and Control

A recent Biopharm International article, Single-Use Bioprocessing Equipment Trends and Adoption by CMOs highlighted this trend:

Single-use systems (SUS)—bioprocessing equipment designed for one-time use or a single product manufacturing campaign—has become the leading paradigm for pre-commercial (preclinical and clinical supplies) manufacturing of biopharmaceutical products (1).

At this past autumn’s Emerson Exchange conference in San Antonio, Texas, Emerson’s Michalle Adkins demonstrated single use manufacturing measurement and control devices and how they could be used to measure and control biomanufacturing operations in a single use environment.

Integrated Simulation for Power Generation Digital Transformation

Emerson's Bob Yeager


We hear the phrase “Digital Transformation” bandied about across the manufacturing industries. For each segment it can mean something different.

At this past December’s Power-Gen conference, president of Emerson’s Power & Water Solutions business’ Bob Yeager gave the keynote address. In his presentation, Digital Transformation of Power: From Concept to Reality, Bob described 3 key reasons why electrical power producers undertake digital transformation initiatives.

Here is Bob’s 20-minute presentation. His part begins at 25:40 into the video.


Forward the video to 25:40 for Bob’s presentation.
