EEPROM Update

The CU1128 features three internal EtherCAT slave controllers (ESCs). This means that three EEPROMs are available for write access. These are different in the CU1128, since all three ESCs have different port technologies (Ethernet or E-Bus); see Fig. The three internal ESC names of the CU1128.

EEPROM Update 1:
The three internal ESC names of the CU1128

The main slave is the CU1128-0000, in this case revision -0000. The two following internal slaves are CU1128-0001 and CU1128-0002.

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.

EEPROM Update 2:
EEPROM Update TwinCAT

All three internal ESCs can be write-accessed sequentially, followed by an off/on restart, in order to load the EEPROM. For assignment in the TwinCAT selection dialog, see Fig. Currently available EEPROM descriptions for CU1128 and assignment.

Dev A is intended for ESC2 CU1128-0001, Dev B for ESC3, CU1128-0002.
