Ethernet APL technology

Ethernet-APL technology Direct integration of APL field devices in the process industry

The Ethernet-APL technology enables consistent IP-based communication via just one wire pair in the Ex zones of process technology applications. This enables the direct connection of APL sensors and devices from the field level, without additional gateways or complex subsystems.

The abbreviation APL stands for Advanced Physical Layer and describes a further development of physical data transmission in Ethernet networks. In addition to data transmission via just one wire pair, the technology also enables power supply transmission over the same wire pair as an option. Advanced Physical Layer uses the 10BASE-T1-L standard in accordance with IEEE 802.3cg along with the IEC TS 60079-47, 2021-03 (2-WISE) standard (2-WISE = 2-Wire Intrinsically Safe Ethernet), and supports explosion protection methods including intrinsic safety. Thus Ethernet-APL enables use in potentially explosive areas and the bridging of great distances up to 1,000 m at 10 Mbps.

Ethernet down to the field level

The APL field switch makes the use of state-of-the-art Ethernet-APL technology simple and efficient. As a managed switch, it ensures secure data transmission with high bandwidth and minimal latency.

APL sensors and devices can be directly integrated from the field level into the existing Ethernet network of the system. This means that process data is available immediately and without any detours. With the two-wire technology, even existing cable infrastructures can continue to be used. This saves time and costs during installation. Complex gateway solutions and additional subsystems, as required in the past, are no longer necessary. The Ethernet-APL switch is the basis for empowering the IIoT in process automation.

Range and speed

Ethernet APL enables large distances to be bridged

Range and speed

The managed APL switches can be used in both compact and wide-ranging systems. The trunk and spur topology is used for long ranges. The 10BASE-T1L standard enables a range of up to 1,000 m (spurs up to 200 m) at 10 Mbps. The bridging of large distances can therefore also be implemented in potentially explosive areas.

Naturally, the network topology can be flexibly designed so that even compact layouts can be realized with the managed switches. It is possible, for example, to do without a trunk by using the APL switches to connect the APL spur ports directly to the standard Ethernet.

Standardized power classes for Ethernet-APL

Simple planning with standardized power classes

Power classes

Ethernet-APL introduces power classes that significantly simplify the selection and installation of devices in potentially explosive areas. The power class defines the electrical properties of a port, i.e., how much power a device can absorb or provide. This ensures that field devices and switches work together optimally and that intrinsic safety requirements are met.

Power class A and B: For intrinsically safe applications (Ex ia) at the field device level, e.g., in zones 0 and 1.
Power class C: Supports Ex ic applications, typically for zone 2.
Power class 3 and 4: For high-performance trunk segments, for example for long cable runs. These ports are not intrinsically safe.

With the clear classification, it is sufficient to match the power class on the switch and on the field device. Elaborate calculations or complex tables are no longer necessary. This increases safety and speeds up commissioning. This in turn makes the installation of Ethernet-APL solutions simple and reliable, even in demanding environments.

Efficient and powerful
The managed APL switch offers Layer 2 functionality with PROFINET MRP capability. This makes the Layer 2 functionality as efficient as possible.
Ready for use
The Ethernet APL switch can also communicate with PROFIBUS PA devices and connect them directly to a PROFINET network. In the event that an APL sensor or device is not yet available, the proxy capability of the APL switch enables the use of a PROFIBUS PA device as an intermediate solution.
Large distances with 10BASE-T1L
The Ethernet APL switch allows the connection of APL sensors with the 10BASE-T1L standard in accordance with IEEE 802.3cg together with IEC TS 60079-47, 2021-03 (2-WISE) standard (2-WISE = 2-Wire Intrinsically Safe Ethernet). The managed switch thus enables use in potentially explosive areas and the bridging of great distances up to 1,000 m at 10 Mbps.
High port density
The large number of 24 ports creates additional space in the control cabinet. Another special feature is that the existing fieldbus cabling can be used. Switching to state-of-the-art Ethernet APL technology is relatively easy, as no additional cabling is required.

Applications

The Ethernet-APL switches can be used in compact systems such as in the pharmaceuticals and chemicals industries, as well as in large systems in the process industry. The integration of Ethernet-APL switches is a decisive step for increasing efficiency and modernizing existing systems.

The managed switches have been specially developed for use in potentially explosive areas. This means that they meet the high requirements for zone 1 and 2 or division 2 accordingly. The robust design and the use of degrees of protection enable the devices to function reliably even under particularly demanding conditions.
