What about Fiber in Hazardous Environments?

Is fiber ok in hazardous environments*? We got this question in one of our PROFINET one-day training classes while explaining APL(Advanced Physical Layer).  Ethernet is not intrinsically safe. Since IEEE 100BASE-TX Ethernet is the base technology for PROFINET, PROFINET cannot reach hazardous environments. There are options to go around this limitation. Some factories employ containment methods such…

Industrial Wireless Architectures- PROFINET

PROFINET can be connected wirelessly as easily and seamlessly as it can be connected with regular wires (copper, fiber). Wireless is part of PROFINET’s specification for two wireless standards: Wi-Fi and Bluetooth. When speaking about wireless PROFINET communications for industrial automation, there are a variety of architectures available depending on the particular application. This post will go…
