PROFINET & Advanced Physical Layer [APL]

“What is the Advanced Physical Layer / APL?” … is a question getting a lot of attention. As of today you cannot land a standard PROFINET cable directly on an instrument that is located in a hazardous environment, where a spark might cause an explosion. (Well, technically, you can do it once. Just once… Kaboom!)…

APL: Bringing Ethernet to the Field

“The realization of this vision began in 2011, when a group of solution suppliers at the urging of several end user groups began a technical investigation of a protocol-neutral, advanced physical layer (a.k.a., APL) that could solve the longtime problem of a long-reach Ethernet for use in hazardous locations.” APL White Paper Description In order…

Show Me the Money

Show Me the Money, or justifying an Industrial Internet of Things project with PROFINET because we like the technology. Dilbert has been known to say, “We’re technology driven.”  But that does not resonate with the owners and their managers – whether the “owners” are stockholders or private individuals. Those folks’ mantra will be some form…

Cloud versus Fog

If the Jeopardy answer is “Cloud, Fog, or Edge,” the question is “Where all can you do analytics?” We rejoice in the PROFINET of Things with its Data Access, Uptime, and Openness, but the Industrial Internet of Things is really about analytics. PROFINET is an enabler. A very important enabler, but still an enabler. The…
