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
