5.3.10 Class ID 2Bh Acknowledge Handler Object
To manage message reception acknowledgements, necessary for change-of-state support, use class ID 2Bh acknowledge
handler object. The attributes supported for this class are listed in
Table 5.15 .
Attribute Access Name Data
type Minimum/
Maximum Default Description
1 Set ACK timer UINT 0–65535 16 Time to wait for ACK before resending.
2 Get/Set Retry timer USINT 0–255 1 Number of ACK-timeouts to wait before
producing.
RetryLimit_Reache event.
3 Get/Set COS UINT – – Connection instance ID

5.4 Danfoss Object Classes
Use the Danfoss classes for read and write of all parameter
values of the frequency converters. A corresponding object
class is defined for each parameter group.
Table 5.16 shows
the classes supported, and their relationship to the
parameters.
The class instance and attribute act in the following way:
•
100 added to the parameter group = the value
for the class.
•
100 added to the remaining parameter number =
the value for the instance.
•
100 added to the array index of the parameter =
the value for the attribute.
