TMDSCNCD28388D: The EEPROM was suspected to be faulty and has been replaced with a new component.

Part Number: TMDSCNCD28388D
Other Parts Discussed in Thread: C2000WARE,

Tool/software:

Hi,

While performing EtherCAT communication verification using dual-core and operating the FLASH, we observed that the TwinCAT could not recognize the Device. Upon debugging the board, it was identified that there was an issue with the output from the EEPROM data.

As a result, we plan to replace the EEPROM with a new component. Could you provide information about the manufacturer and product number of the EEPROM?

Additionally, is it possible that the EEPROM malfunctioned because incorrect data was written to it during the initial FLASH operation?

Thanks.

    Hi,

    Full design files for the eval board can be found in C2000WARE. I2C EEPROM component is 'CAT24C16WI-GT3'

    Did it ever work and were you able to program the EEPROM using TwinCAT the first time?

    Normally data is only written to the EEPROM by using TwinCAT or other eCAT master. Were you ever able to scan / connect while running ECAT software?

    Best,

    Thank you for your kind response.

    The issue with the EEPROM malfunction has been resolved.

    The problem occurred because the EEPROM data was not transmitted through TwinCAT3 during the initial board startup.

    Thank you.
