Advanced Physical Layer (APL)

The launch of Ethernet-APL (Advanced Physical Layer according to IEEE 802.3cg) opens up new possibilities for the process industry.

The process devices can communicate robustly with high data rates on existing 2-wire lines, even in explosion-proof areas. They are supplied with voltage via the communication line using PoDL (Power over Dataline). They are fully integrated into the Ethernet topology of the overall system.

Ethernet-APL thus enables the consistent use of established Ethernet protocols (non-safe and safe) from the sensor to the controller. This has considerable advantages in terms of device installation, configuration and maintenance. In addition, safety protocols can be used for safety-related tasks in the field devices.
