Procedure
- The procedure concerning handling of the password for access to a device by ETS is as follows:
- If a password is set in the project and the device is locked with the same password, there is no query by ETS (the normal case).
- The ETS query should only be issued if the device is locked with a password that is not the same as the project BCU Key. Or, if the password is correct, but ETS cannot reach at least access level 2 with it, (for a definition of the access level, see the KNX Specification; usually 3 are available, 0 .. 2 are required for configuration using ETS).
Notes
- If no BCU Key has been assigned, the text field remains blank. If a BCU Key has been assigned, this is indicated by "llll" in the text field.
- This field is not case-sensitive (because in the end, a 0x0a/0x0A always leads to 10d)
- The password can be up to 4 bytes long; the entry must be made in hexadecimal form with a maximum of 8 characters [0-9,a-f, A-F]; e.g. as "11AA00FF" or "11aa00ff" (equals 296354047 decimal).
