Web现场总线控制系统（Fieldbus Control System,FCS）是分布控制系统(DCS) 的更新换代产品，并且已经成为工业生产过程自动化领域中一个新的热点。现场总线技术是20 世纪90年代兴起的一种先进的工业控制技术，它将现今网络通信与管理的观念引入工业控制领域。从本质上说，它是一种数字通信协议，是连按 ... WebJan 24, 2024 · The FCS field contains a 4-octet (32-bit) CRC value. This value is computed as a function of the contents of the protected fields of the MAC frame: the Destination Address, Source Address, Length/ Type field, MAC Client Data, and Pad (that is, all fields except FCS). The encoding is defined by the following generating polynomial.

The Ethernet FCS's purpose is to detect rather simple errors and drop damaged frames as soon as possible (ie. do not forward corrupt frames). It cannot guarantee 100% integrity (actually, nothing can really do that). However, since the FCS is checked on each switch hop, errors can't pile up and it's more effective than it sounds.
