Understanding Machine Safety Analysis In The U.S. (Part 1)

Posted by Karl Schrader on December 11, 2012 @ 11:17 am

A few years ago, I was working with an internal integration group for a manufacturing company which had facilities in many domestic and international locations. One of the initiatives I had undertaken was to redevelop procedures for assessing safety hazards on automated equipment. Safety_WorkPlace_MachineWith the planned adoption of the International Standards Organization document ISO:13849-1:2006, the older EN-954 standard was slated for retraction by the European Standards Organization. Anticipating this retraction, we needed to take another look at our own risk analysis and mitigation procedures in order to maintain complia...

Who Will Be In Your Control Room In 2016?

Posted by Bill Tolrud on December 5, 2012 @ 1:29 pm

Control SystemsTake a look at the people in your control room: you probably see a lot of gray hair. How many of those individuals are still going to be there in another three or five years? To answer this question, we need to look at the retirement rate of the baby boomers that are now between the ages of 55 to 65. On January 1, 2011, the first baby boomers turned 65. According to a report from the Congressional Research Service, dated January 30, 2008, the retirement of baby boomers will affect the overall economy and our industries until the year 2020. The industries affected most will be those that have been part of the structure of the U.S. industry buildup: steel and primary m...

More Than A Story, A Process Narrative Can Define Your Next Automation Project

Posted by Jason Montroy on November 27, 2012 @ 10:55 am

I recently sat down with an automation manager responsible for a subsection of a large manufacturing business. His company is embarking on an effort to standardize the use of process control narratives for all automation projects. To my surprise, the concept of process narratives was new to him. He didn't understand their purpose. But he was intrigued and asked many good questions I was happy to answer.

What is a process narrative? MAVERICK_Blog_Automation

Simply put, a process control narrative is a written description of a manufacturing process that d...

HART: New Lease On Life

Posted by Sergei Kuznetsov on May 8, 2012 @ 8:56 am

Working in our industry it is impossible to avoid bumping into the HART Communication protocol. Introduced in the mid-1980s by Rosemount as an attempt to find an inexpensive, almost trial way to get more information from smart field instrumentation, it later developed into something that finds its way back even when it seems to have outlived its purpose. I won’t get into the details as to when, why, and how the HART standard was developed and how it works. It’s common domain information, but in a nutshell it utilizes low-frequency carrier to communicate digitally with intelligent field instruments. For point-to-point connection with an instrument, even the existing 4-20 mA cables can be used – leaving the main variable to the current signal and using digital communications for auxiliary information. It’s the best of both ...
