Figure 1: Controllers, networking equipment, and operator interface software are the three most specified or used technologies with use, connect with, or support mobility, Ethernet, or wireless technologies. Safety devices were used by 31% of respondentsNetworked safety for PI North America involves using ProfiSafe, an additional software layer used on top of Profinet (industrial Ethernet) and Profibus (device-level) networks. According to the organization, ProfiSafe:

  • Adds functional safety to an existing automation network, running on the same cables.
  • Compared to wired circuits, requires less engineering, less cable, faster commissioning, and easier maintenance.
  • Has been available since 2001 with nearly 7 million ProfiSafe devices in operation in 2016.
  • Can be used with wireless (such as WLAN and Bluetooth) and with open Ethernet backbones.
  • Works by reducing error probabilities in transmitted data between certified devices and controllers and includes safety checks.
  • Operates without interference, avoiding impact on connected standard bus protocols and automation systems.
  • Can be used for safety applications up to SIL3 according to IEC 61508/IEC 62061, or Category 4 according to EN 954-1, or PL "e" according to ISO 13849-1.

To implement ProfiSafe, one must first assess risks, determine a mitigation strategy (including controls, guarding, signage, etc.), use a ProfiSafe controller and input and output (IO) devices, and finally, reassess periodically. ProfiSafe also can integrate AS-i Safety at Work, said Michael Bowne, PI North America, executive director, citing ProfiSafe training materials.

Of the industrial Ethernet protocols, Profinet ranked third, in the 2016 Mobility, Ethernet, Wireless Report from Control Engineering. Courtesy: 2016 Mobility, Ethernet, Wireless Report
