Cableless (Wireless) Operator Panel Applications

04/02/2010


Cableless (wireless) operator panels for machine applications, in my opinion, need special application considerations for appropriate and safe use. True, we often talk about how a wireless field bus and a wired field bus have many similarities. Even when they are safety certified for functional safety applications they continue to have many similarities. However, there are several application recommendations available to ensure that utmost care is exercised in planning and execution of cableless (wireless) operator panel. In no particular order, some of the recommendations are as follows:

  • Choose a supplier with a track record of successful applications having NRTL (Nationally Recognized Testing Laboratory) tested and certified products for safety applications.
  • Make sure your Risk Assessment for the application is up to date and identifies any hazards presented by a cableless (wireless) solution.
  • Research current/available industry standards and regulations addressing your application.
  • If at all possible, complete a functional specification for the application and make sure any safety related functions are identified.
  • Consult heavily with your supplier for their application/installation recommendations.
  • Consider best practices and lessons learned.
  • Perform a complete checkout of all normal and safety functions.
  • to mention a few……………

Remember that “Murphy’s Law” say’s that the unforeseen is likely to happen so keep in mind that responsible suppliers put limits on their products and applications to increase their reliability. Given this to be the case, it’s my opinion to always stay within the supplier’s specifications and recommendations for the greatest assurance of reliability and safety compliance. Often times there are cost saving advantages for utilizing cableless (wireless) operator panels but only if their reliable and safe.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
