Next-gen industrial communications solve networking problems

Posted by Garrick Reichert on Oct 1, 2018 8:00:00 AM

Working in systems integration often means putting on many hats. Sometimes you can just fulfill your normal duties of designing, building, and commissioning a controls/automation system.

But then other times you find yourself thrown into the mix as the sales estimator—asked to come up with a budgetary number for a project—or you’re deemed the “IT” person for a project.

Being designated the “IT” person can be a difficult road to navigate. Often you’re not truly an admin on any given network, but you’re asked to perform the duties of an admin.

What gets measured, gets managed... gets improved

Posted by Garrick Reichert on Sep 11, 2018 11:19:00 AM

The adage “what gets measured, gets managed” is an old one[1], and I had heard it many times, but a director of mine in a previous job put a new spin on it: “What gets measured, gets managed, gets improved.”

Outbound! Monitor OEM machinery with little to no IT involvement

Posted by Dan White on May 10, 2018 7:00:00 AM

Day in and day out, I work alongside machine builders who share a common problem: Once equipment has been shipped to a customer site, it is quite difficult to ensure that it is running properly and being adequately maintained.

I once heard the phrase, "even a Cadillac will fail prematurely if you drive it into a brick wall." Premature failure of the machinery (regardless of whose fault) can tarnish the image of the manufacturer, lead to increased warranty costs, and create tension between OEMs and end users.

But how do I (the machine builder) get access to the control system if it is operating inside a customer’s firewall?

Request-response vs. publish-subscribe, part 2: Which to use?

Posted by Jean Femia on Feb 27, 2018 10:00:00 AM

In part 1 we met two communication models for computers on a network: request-response and publish-subscribe. Now let's take a look at when you might want to use each, and why.

Request-response: proven and reliable

In a request-response architecture, each client opens a direct connection to each server, because the client requests data directly from the server.

In automation, typically clients are PCs and servers are PLCs or PACs. So each PC opens a direct connection to each PLC or PAC from which it needs data.

Request-response vs. publish-subscribe, part 1: What's the diff?

Posted by Jean Femia on Feb 8, 2018 11:17:12 AM

We all know that computers and other electronic devices—printers, routers, laptops, smartphones, and more—are networked so they can exchange information.

But how does that information get where it’s supposed to go?

How does a spreadsheet get to the printer, a YouTube video get to your smartphone, or—most important for automation engineers—a value from a sensor get to your HMI?
