To reconfigure the PDC data outcoming from the Master it is necessary to interrupt the data transfer to the
drive parameters.
This is the task of the communication object Output

Every Bit of the output object is assigned to a Byte of the Process Data
Channel.
The meaning is the following:
Bit = 0 The assignment of the Byte to a drive parameter is disabled.
Bit 1 The assignment of the Byte to a drive parameter is enabled.
If an drive parameter occupies more than one Byte, the Bit assigned to the first Byte becomes significant.
This corresponds to the position of the drive parameter both in the object output data
and in the object input data Descriptor The remaining Bits have no importance.
With the writing of the object PDC output data Descriptor>> the data transfer of the PDC data outcoming
from the Master is automatically interrupted; this is possible by clearing the corresponding control Bit in
Output Enable)).
Example 1:
If the assignment of the first parameter in the output data Descriptor)> is modified, the Bit 0 is
cleared. The remaining Bits do not change.
Example 2:
If the assignment of all parameters output data Descriptor is modified, all the Bits are cleared.
