Drop Numbers
Drop numbers are used to uniquely identify every rack on the
Remote I/O network; therefore, a drop and a rack are the same entity
on a Remote I/O network. There are a maximum of seven slave drops
on a Remote I/O network, each identified by the rotary switch (Shark)
or thumbwheel switches (Remote I/O module, Remote Drive Interface
Head, and Remote I/O Heads) on the faceplate. For Remote I/O
modules drop numbers 0 through 7 are valid, with drop 0 always
being reserved for the master Remote I/O module. For all Remote
Heads, only drop numbers 1 through 7 are valid.
For Shark racks, which can only be slave drops, the drop number
setting should be selected based upon the I/O module complement
in the rack. A rack containing digital modules only should be set to
drop numbers 9 through F. This allows faster network throughput.
Note that drop numbers 1 through 7 will also work for racks
containing only digital modules; however, the total network
throughput will be slower with this setting. See section 4.5 for
information on network throughput.
A Shark rack containing mixed digital and analog (numeric) or all
analog modules must be set to drop numbers 1 through 7. No other
drop numbers are valid. In addition, you must also write a
configuration word in the AutoMax application program as described
in section 4.6.1. See figure 2.5 for valid drop number settings.

OK = valid setting
OK* = valid setting, but will result in lower throughput
X = not a valid setting
N/A = not applicable, i.e., the setting is unavailable
Note: If you are using settings 9 through F on any drop on the remote I/O
network, see figure 2.6 for more information
