Industrial Ethernet

Industrial Ethernet systems require a high degree of determinism and reliability. In many factory automation applications, Ethernet has replaced legacy serial "field bus" connections because of its higher bandwidth and ability to link with enterprise networks, But Ethernet did not inherently have the deterministic response of field bus systems.

To overcome this limitation, the major industrial OEMs each defined their own Ethernet protocols, which have since become widely-deployed open standards: PROFINET, EtherNet/IP, EtherCAT, ModbusTCP, and several others. Some of these protocols are fully compatible with standard TCP/IP Ethernet networks; others have modified the data link, network, and/or transport layers (layers 2-4 in the OSI model) to achieve deterministic performance. Although these protocols can coexist with standard Ethernet, they are not interoperable with each other in a deterministic way.

The challenge when designing products that need to support industrial Ethernet is to select a reference design which is compatible with a variety of different standards. Another important factor to consider is whether the solution can be updated to provide support for future enhancements such as TSN.

Your Processor, Your Stacks, One Switch—Amazing Performance

The fido5000 REM switch supports all major Industrial Ethernet protocols and connects to any processor to build any field device or controller application. The fido5000 REM switch is a 2-port, embedded Ethernet switch that interfaces to any processor, including any ARM® CPU and ADI’s fido1100® communication controller. ADI’s PriorityChannel™ technology has been integrated into the switch’s hardware architecture and designed into the REM switch software drivers. The protocols supported for both the fido5100 and fido5200 are PROFINET Class C (IRT) and Class B (RT), EtherNet/IP with and without DLR, Modbus TCP, EtherCAT, SERCOS, and POWERLINK; the fido5200 adds EtherCAT support. The REM switch comes with a software driver for each protocol. The software drivers provide an API for integration with any field device or controller protocol stack. ADI is certifying REM and its software drivers at each protocol’s sponsoring industry organization using ADI’s RapID platform.

webinar-spotlight-imageWebcast: How Ethernet brought determinism to a wider range of industrial systems

At one time, determinism in industrial networks was mostly limited to coordinated motion and CNC-style applications. In fields such as energy and certain types of manufacturing, the assumption was that the efficiency boost provided by determinism wasn’t necessary, given the benefits from increases in Ethernet speeds and the gradual replacement of serial networks with Ethernet-based protocols.

Ensuring determinism in a standard (IEEE 802.3 Ethernet) that did not initially contain it was also problematic, but that began to change with the codification of full-duplex switched Ethernet in the 1990s and the development of commercial industrial Ethernet protocols.
