Web8 Nov 2024 · The situation for the Ethernet-APL spurs is the same for all three topologies. Ethernet-APL devices can be connected to a switch by a Category IV cable no more than 200 m in length and can communicate at a transmission rate of 10 Mbps. In the first topology scenario discussed, an APL field switch is connected directly to a standard Industrial ... WebThe trunk and spur topology is used for greater range. The Ethernet APL switches installed in the field are intended for use in potentially explosive areas (zones 1 and 2 or division 2), so that all increased demands regarding explosion protection can be met with the degrees of protection of increased safety or intrinsic safety.
