工业以太网

工业以太网系统需要高确定性和可靠性。在许多工厂自动化应用中,由于以太网具有更高带宽且能够与企业网络链接,它已替代传统的串行“现场总线”连接,但是以太网本身不具备现场总线系统的确定性响应。

为克服这一限制,各主要工业OEM制定自己的以太网协议,自此成为广泛使用的开放式标准:PROFINET、以太网/IP、EtherCAT、ModbusTCP和其他几种标准。其中一些协议与标准的TCP/IP以太网网络完全兼容;其他协议已修改数据链路、网络和/或传输层(OSI模型中的2-4层)以实现确定性性能。虽然这些协议可与标准以太网共存,但它们不能以确定的方式实现彼此互操作。

需要支持工业以太网的产品设计挑战为选择兼容各种不同标准的参考设计。另一个需要考虑的重要因素是能否更新解决方案以支持未来的增强功能,如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.
