Example: Configuration message for IC200MDD844
The following example shows the Read Configuration Data Reply
datagram for a mixed discrete I/O module, the IC200MDD844. This
module contains a 16-point output board as its primary board and a 16-
point input board as its secondary slot.

Rack (e.g., Rack 0, the rack containing the GNIU)
Message length (e.g., 82 bytes total length)
Slot (e.g., 3, the second I/O slot)
Offset into configuration data
(e.g., zero because the configuration fits in one message)
secondary board ID (e.g., the ID is 0x8008. The LSB is in
byte 0, and the MSB is in byte 1.)
primary board ID (e.g., the ID is 0x8080. The LSB is in byte
2, and the MSB is in byte 3.)
ASCII string. Set to zeros during auto-configuration, the
programmer may fill this field with an arbitrary
identification string. (e.g., this is the ASCII label "D844")
Length of additional data, excluding pad bytes
not used (must be 0)
Total Length of additional data (e.g., 52 bytes)
secondary board ID (same as above.)
(e.g., discrete DC type, no diagnostic bits, no outputs, eight
pairs of inputs)
primary board ID (same as above)
(e.g., discrete DC type, no diagnostic bits, eight pairs of
outputs, no inputs; there are two boards in this module.)
