摘要
Abstract
Applying the office communication protocol of Ethernet to the field would reduce the cost of hardware ;invest of the education and cost of service .So there are many industrial Ethernet protocols .Some of them were approved as international standards .There is a tendency to focus the functional safety ,hence the scrutiny of available technologies is needed .This paper shows that the coding in 100M Ethernet will cause the error number in channel be amplified that makes the CRC check less effective .Even the supplemented CRC check in so called“safety protocol”is also not enough .关键词
