Read attribute
This service can be used for reading the access attributes and the index of the next parameter. The following table shows the coding of the data for this parameter service.
Byte 4 | Byte 5 | Byte 6 | Byte 7 |
|---|---|---|---|
MSB data | Data | LSB | LSB data |
Next available index | Access attributes | ||
The coding of the access attributes is unit-specific. For MOVITRAC® B inverters, the attribute definition results from the following table:
Byte 6 | Byte 7 | |
|---|---|---|
Bit | Bit | Meaning |
0 | 1 = Parameter allows write access | |
1 | 1 = Parameter is permanently saved on EEPROM | |
2 | 1 = Factory setting overwrites RAM value | |
3 | 1 = Factory setting overwrites EEPROM value | |
4 | 1 = EEPROM value is valid after initialization | |
5 | 1 = Controller inhibit condition not necessary for write access | |
6 | 1 = Password required | |
8 | 7 | 00 = Parameter is generally valid 01 = Parameter is assigned to parameter set 1 10 = Parameter is assigned to parameter set 2 11 = Parameter is assigned to both parameter sets |
9 - 15 | Reserved |
