3.2.2.6 Behavior
This object is the interface between the DeviceNet networkand all parameters
of the optional DGF card that can be mounted on the drive. The access to the
DGF parameter is made by the parameter index and the data type: if the
parameter does not exist or cannot be accessed for any reason (i.e. try to write
a read only parameter) a specific DGF error code is returned.
Hereafter are reported patterns of how to compose the data frame for read/
write DGF parameters.
3.2.2.6.1 Write DGF parameter
In this example the writing of a DGF parameter is reported; cases of positive
and wrong writing are distinguished.
