Ethernet-APL gears up

The speedy, two-wire, single-pair Ethernet (SPE) network prepares to work in intrinsically safe (IS) and other hazardous areas
Figure 1: Endress+Hauser load tested an Ethernet-APL network and components by integrating 238 field devices into an Ethernet-APL system at its headquarters in Reinach, Switzerland. It deployed field switches from Pepperl+Fuchs and controls from Honeywell and ABB. The two tests found that Ethernet-APL provided increased bandwidth and speed for easier data access and improved transmission from the field. Source: Endress+Hauser

Ethernet-APL mini-series—Day 2—Standards development organizations weigh in
Figure 1: To evaluate Ethernet-APL networking, communications and devices via Profinet protocol, BASF built a field test lab in 2019-20 at its headquarters in Ludwigshafen, Germany. The lab tests flowmeters, level, pressure and temperature transmitters, valve positioners, sensor sets, and other components, which is helping its supplier partners develop Ethernet-APL products.
