In the process industry, Ethernet-compatible interfaces are increasingly needed to access data from the field via IIoT. The Ethernet APL (Advanced Physical Layer) technology enables direct access down to the field and device level via an internationally standardised two-wire solution. This requires powerful IIoT devices with qualified components. For this purpose, Weidmüller has comprehensively expanded its portfolio of data connectors, thus enabling a consistent data infrastructure for Industry 4.0.
With Ethernet APL, the process industry relies on classic terminals with screw or spring connections. Here we offer you a wide range of suitable components, such as OMNIMATE® PCB components, built-in and field attachable connectors (M12):
There‘s the challenge that information is required from sensors and devices in the field, with large distances to be bridged. In addition, various IIoT devices must be integrated into the network infrastructure. There is only limited space for RJ45 or M12 connectors in the device.
Ethernet APL enables direct connection via a two-wire solution using cost-effective PCB components from Weidmüller. Transmission is possible over distances up to 1.000 m. In addition, data and voltages can be transmitted on just one line (PoDL).
By this you will get an increased plant availability and production data: The collection, use and analysis of data from devices in the field is possible easily to ensure and increase plant availability and to implement new solutions.
In the process industry, Ethernet-compatible interfaces are increasingly needed to access data from the field via IIoT. For sure this can also include the hazardous areas, in which special protection and corresponding approvals are needed. But not only. Also in the process industry there are still a lot of sensors and devices in the field out of hazardous areas, which are not connected via Ethernet yet. There’s a wide range of Industry 4.0 applications to connect all IIoT devices via Ethernet APL, which is compatible with all common protocols such as PROFINET, EtherNet/IP, or EtherCAT.
When you have the challenge in the process industry to integrate IIOT devices into the network infrastructure, our Ethernet APL components can help you with Ethernet-compatible high-speed data transmission with a top performance of 10 Mbit/s. Ethernet APL enables direct connection via a two-wire solution using economic PCB components.
Within compact field devices there is limited space for RJ45 or M12 connectors. The Ethernet APL PCB components reduce space and weight.
Although the process industry is the target market for Ethernet APL, our components can also support you to integrate IOT devices into the building network infrastructure and cover long distances.
Ethernet APL enables direct connection via a two-wire solution using cost-effective PCB components from Weidmüller. It is possible to bridge large distances of up to 1,000 m.
In fact, Ethernet APL is a part of Single Pair Ethernet. In the process industry, Ethernet-compatible interfaces are increasingly needed to access data from the field via IIoT, too. Single Pair Ethernet describes different Ethernet standards, which are all based on a two-wire technology: 10Base-T1S, 10Base-T1L, 100Base-T1, 1000Base-T1. With these standards different transmission speeds are described from 10 Mbit/s up to 10 Gbit/s and a cable length from 15 m to 1000 m.
Herein Ethernet APL is a dedicated definition of 10Base-T1L and needs qualified components which allow reliable data transmission at 10 Mbit/s and simultaneous power supply via twisted pair cable up to 1,000 m.
You can say that Ethernet APL is the Single Pair Ethernet for the process industry. Within the Ethernet standard certain requirements were added to describe characteristics of cables and plugs, power supply and explosion protection in hazardous areas. While Single Pair Ethernet will mainly be used in factory automation and building infrastructure, Ethernet APL was specifically developed for the process automation industry and the components need to fulfil the special requirements in that area.
Single Pair Ethernet for industry and building automation mainly considers connectors with miniaturized mating faces, patch cables, field attachable plugs, M8 adapters as well as IP20 and IP67 sockets in different outlet directions. Regarding the APL specification the process industry relies on classical terminals with screw or tension spring connection.
