    Figure 1: In a recent demonstration at Hannover Fair 2025 in Germany, Pepperl+Fuchs showed how its FieldConnex Ethernet-APL Ex ia intrinsically safe (IS) rail field switch with eight, 16 or 24 APL ports and its web-based interface work with Endress+Hauser’s Cerabar PMC 71B transmitter and Samson’s Trovis 3797 valve positioner, which both have the interface built in to communicate via Ethernet-APL with the communication protocol of any switch or controller that supports it.
