EEPROM update

The EP9128 features 3 internal EtherCAT slave controllers (ESC). This means that 3 EEPROMs are available for write access. In the EP9128 they are different, since all 3 ESCs have different port technology (Ethernet or E-bus), see Fig. 1.

The main slave is the EP9128-0000, in this case revision -0000. The two following internal slaves are EP9128-0001 and EP9128-0002.

The EEPROM can be updated via the EEPROM Update dialog in the System Manager. This is only necessary in special cases and should only be done if instructed by Beckhoff support/service.

All 3 internal ESCs can be write-accessed sequentially, followed by an off/on restart, in order to load the EEPROM. See Fig. 3 for assignment in the TwinCAT selection dialog.
