摘要： An industrial automation system using transformers for providing electrical isolation between a system interface chip and a load interface chip while simultaneously allowing communication of power and data across the isolation barrier. Clock pulses are transmitted from the system interface chip to the load interface chip across one transformer, and the clock pulses are used by the load interface chip to create a power supply for operating the components within the chip. Data is communicated from the system interface chip to the load interface chip across a second transformer by the use of messages. Each message comprises a bit sync field, a byte sync field, and a data field. The bit sync field and byte sync field are used by the load interface chip to synchronize itself with the system interface chip. Transmission and reception of data by the chips are interleaved on a bit-by-bit basis, wherein a bit is transmitted from the load interface chip to the system interface chip after each bit is transmitted from the system interface chip to the load interface chip. After each byte of data is transmitted and received by the chips, the load interface chip eliminates synchronization between the chips, and must resynchronize itself with the system interface chip in order to transmit and receive the next byte of data.
摘要翻译：一种使用变压器的工业自动化系统，用于在系统接口芯片和负载接口芯片之间提供电气隔离，同时允许跨越隔离屏障的电力和数据通信。时钟脉冲从系统接口芯片通过一个变压器传输到负载接口芯片，并且时钟脉冲由负载接口芯片使用，以创建用于操作芯片内的部件的电源。通过使用消息，数据通过第二个变压器从系统接口芯片传送到负载接口芯片。每个消息包括比特同步字段，字节同步字段和数据字段。位同步字段和字节同步字段由负载接口芯片用于与系统接口芯片同步。每个比特从系统接口芯片发送到负载接口芯片之后，由芯片进行的数据的传输和接收是逐位交织的，其中从负载接口芯片向系统接口芯片发送一个比特。在每个字节的数据被芯片发送和接收之后，负载接口芯片消除了芯片之间的同步，并且必须与系统接口芯片重新同步，以便发送和接收下一个数据字节。
