How do you gauge the growth of your favorite technology without an expensive market company study? (PROFINET being the technology; it’s my favorite.) One way is the number of people coming to the free one-day training classes. (An ever-increasing number.) A second is those taking the next step and clamoring for the next class – the full week Certified Network Engineer class. (We’ve had to add a class for July 27-31. Seats still available.) Third, how busy are the test labs in certifying new PROFINET products. (Really, really busy. Device manufacturers need to reserve their test slot early!) The economy may be down, but clearly many of you are using this time to prepare for the inevitable upturn.
