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.

Ethernet-APL & OPC Foundation cooperate

The cooperation between the OPC Foundation and the Ethernet-APL consortium will enable Ethernet-APL / OPC UA interfaces in the future. MESCO follows this trend and is expanding the Ethernet APL service accordingly: PROFINET / OPC-UA / MQTT communication can be implemented in field devices.


New HART® Slave Stack version 7.7

MESCO launches the latest version of its portable protocol software for HART field devices. HART Slave Stack 7.7 offers a quick and easy solution for communication that corresponds completely to the HART fieldbus system. A detailed documented interface for API simplifies integration and porting even further. The pre-certified software cuts development times considerably.


Review: Online Round Table TÜV NORD & MESCO

The high-quality Safety & Security Webinar on May 5, 2021 was extremely well attended with well over a hundred permanently connected listeners. The specialists from MESCO and TÜV NORD reported in detail on the complex environment of functional safety.
