Close the Gap! Industrial Ethernet in process automation
Process automation goes Ethernet
The upheaval in process automation begins at the moment when Industrial Ethernet finds its way into the production plant. With the standardization activities around IEEE802.3cg, the first Ethernet Phys for SPE (Single Pair Ethernet) are now available. However, there is another challenge. The additionally occurring explosive atmospheres require an ATEX-compliant design.
In order to achieve intrinsic safety, extremely low energy budgets are necessary. With the lowest possible use of energy, not only can standard-compliant communication be established via Ethernet APL and PoDL, but an example of an IEC61508-SIL2-compliant and ATEX intrinsically safe sensor can also be shown. PROFINET is used over a black channel to route bare PROFIsafe packets to a safety CPU, which in turn is monitored by a separate test entity.
You can find out more about this at the Online Forum Safety & Security 2021 (seminar language: German). In a specialist lecture, Gerhard Weiß, R&D Manager at MESCO in Freiburg, explains the mechanisms for implementing safety functions over the large distances in the production and how an ATEX-compliant design can be set up.
