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.
