SII EEPROM
Slave Controller Technology I-73
11.1 SII EEPROM Content
The ESC Configuration Area (EEPROM word addresses 0 to 7) is automatically read by the ESC after
power-on or reset. It contains the PDI configuration, DC settings, and the Configured Station Alias.
The consistency of the ESC Configuration data is secured with a checksum.
For SII coding refer to ETG.1000 EtherCAT Specification, Part 6, Clause 5.4, available in the
download area of the EtherCAT Technology Group website (http://www.ethercat.org).
The EtherCAT master can invoke reloading the EEPROM content. In this case the Configured Station
Alias register 0x0012:0x0013 and ESC Configuration register bits 0x0141[1,4,5,6,7] (enhanced link
detection) are not transferred into the registers, they are only transferred at the initial EEPROM
loading after power-on or reset.
The ESC Configuration Area is shown in Table 37.

NOTE: For debugging purposes it is possible to
disable the checksum validation with a checksum

NOTE: Reserved words or reserved bits of the ESC Configuration Area should be filled with 0.
