Special boot state of the EtherCAT state machine
Chip Select (SPI bus signal)
EtherCAT (or sometimes used for EtherCAT Master Interface)
Electrically Erasable Programmable Read Only Memory. Non-volatile memory used to
store EtherCAT Slave Information (ESI). Connected to the SII
EtherCAT Network Information file, holds information on the complete EtherCAT bus
structure and its connected slaves
End of Frame
EtherCAT Slave Controller
EtherCAT Slave Information, stored in SII EEPROM, holds slave specific configuration
information
