9. Exchanged Data Structures

9.1 Output (Control) Data Format

The size of the output data structure from the network master to the PBDP-110
depends on the module selected from the GSD file for the network configuration tool.
Module #1, intended for applications where only 1 drive is connected to the PBDP-
110 (via Channel A), is comprised of 16 bytes structured as four 32-bit words.
Module #2, intended for applications where drives are connected to both Channel A
and Channel B, is comprised of 32 bytes structured as eight 32-bit words.

Locations marked "Reserved" in the above table are reserved for future use.
Although any data placed in these locations is currently ignored, future firmware
releases may use these locations for data transfer.
The format of all information transferred for Drive B is identical to that for Drive A.
Therefore, all data descriptions given here apply equally for both Drives A and B.
