Modern Edge Devices Bring Harmony to Disjointed Protocols

Posted by Dan White on Aug 19, 2024 12:44:04 PM

Without disturbing existing systems, edge devices make it easy to convert data from a custom fieldbus into open protocols for digital transformation.

If TCP/IP won the “protocol wars” in the ‘90s, then WHY are you still fighting protocol battles on the plant floor today? Because industrial networks were around long before the internet. As far back as the 1960s, machines communicated via serial networks like RS-232, RS-485, and CAN Bus—with specialized proprietary fieldbus protocols like Modbus, Profibus, and DeviceNet.

Even with TCP/IP on Ethernet, specialized protocols remained. Modbus now has a TCP/IP version, Profibus gave way to ProfiNET, DeviceNet to EtherNet/IP, and even some new ones joined the protocol party.

After the industry demanded interoperability, OPC was born—now OPC UA—a big step toward a unified architecture on OT networks. Meanwhile on the IT side, using HTTP and HTTPS was common. It’s how web browsers—and most of the internet—work today.

MQTT Sparkplug came later. A recently named International Standard, it’s built on efficient, secure, and scalable publish/subscribe communications—a great fit for digital transformation projects and the IIoT.

I want to digitally transform, but my existing machines don’t support all these protocols.

OT SCADA CON—An Engaging and Efficient Format

Posted by Dan White on Jul 29, 2024 12:03:43 PM

Why a first-of-its-kind event is changing the world of SCADA.

Attending the inaugural OT SCADA CON in Houston can only be described as “a breath of fresh air.” I attend a lot of automation industry events, and this one was a hit—thanks in large part to its excellent format.

Informative sessions were kept to 30 minutes—a block of time long enough to highlight each speaker’s real-world experience and expertise, but short enough to keep the audience engaged, attentive, and in some cases, QUITE entertained.

50 years of Opto 22 - a personal perspective

Posted by Dan White on Jul 22, 2024 9:33:28 AM

In 1974, Robert Engman III stared down at 22 optically isolated, highly reliable, liquid epoxy-filled, solid state relays (SSRs) with no moving parts—quite an innovation back then—and he contemplated what to name the new company.

The result? "Opto" signifies optical isolation, and the "22" represents the original lineup of 22 relays. But this year, there’s another important number that we need to discuss—50!

Yes, Opto 22 is 50. Years. Young

This week, as we celebrate Opto’s Golden Anniversary of existence, I’d be remiss not to reflect on the legacy of a company I have loved being a part of for the last decade. And while my 11 years may seem like a long time, many of the folks I work with each day have tenures twice or thrice as long—they’ve been carrying the torch, maintaining the legacy that we are still building today.

Energy management starts with energy monitoring

Posted by Dan White on May 8, 2024 8:25:33 AM

Start analyzing your energy data to manage and reduce your energy consumption.

Managing and reducing your energy consumption sounds like a no-brainer. Save thousands on electricity, maintain critical machine health, reduce carbon footprint? Sign me up! 

Where to begin? Well, the best place to start is analyzing your energy data, but unfortunately, you can’t find that data on your electric bill—it’s barely a summary. To manage your energy, start by measuring it. Once you determine where, when, and how that energy is consumed, areas for improvement become obvious.
