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).
The password protection applies to the following EL5072 user data:
- 0x80n1:1C User Offset
- 0x80n0:1D User Gain
- 0x80n5:0 IND Scaler Settings Ch.n
