Layer Architecture

EC-Master / embedded consists of the following components:

Application Interface Layer: Interface to the EtherCAT master. EtherCAT Master Core: The main EtherCAT master functionality in the core layer. All protocol handling, e.g. process data transfer and mailbox protocols (CoE, EoE, FoE, SoE) are executed here. Ethernet Link Layer: Data ex改变 between master and slaves. Zero-copy and/or polling techniques together with the core layer are supported to achieve best real-time performance and minimize CPU load. Configuration Layer: An OS independent XML parser supports the General Ex改变 Format defined in the EtherCAT specification. 操作System Layer: The only OS specific layer. All operating system calls are executed here. To achieve best performance the most functions can be implemented using simple "C"-language macros.
