Password protection for user data

Some user data are protected against unwanted or inadvertent writing by an additional password to be entered in CoE 0xF009:

  • CoE write accesses by the user, PLC or startup entries in Single- or CompleteAccess mode
  • Overwrite the values by RestoreDefaultParameter Access to 0x80n0 and 0x80n5.

Use of CoE 0xF009

  • Entering 0x12345678 enables password protection → Object displays "1" (enabled).
    Protected objects can now no longer be changed. A write access attempt results in an error message, e.g.:
    CoE ('InitDown' 0x8011:1d) - SDO Abort ('Data cannot be transferred or stored to the application because of local control.', 0x08000021).
  • Entering 0x11223344 disables password protection → Object displays "0" (disabled).
