9.4 Profibus Exchanged Data Structures
9.4.1 Output (Control) Data Format
The size of the output data structure from the network master to the Multicom interface is modular and
selectable from 4 to 40 bytes. The allocation of the maximum 40 bytes of the data structure is
comprised of 1 fixed four-byte command, 1 fixed four-byte extended command, 1 fixed four-byte speed
reference, 5 configurable four-byte scan data selections (selectable via drive parameters F831-F835),
and 1 eight-byte structure for asynchronous parameter accesses. Refer to Table 9 for details.

Locations marked “Reserved” in the above table are reserved for future use. Presently, all “Reserved”
output data locations are ignored by the drive. Future releases of the drive firmware, however, may use
these locations for data transfer.
