Global Data Format
Global Data is used to automatically broadcast up to 128 bytes of data from one host to all others
on the Genius bus. Typically, this data is a collection of both discrete and analog values. To
facilitate transmitting/receiving global data as either discrete or analog values, a double mapping
scheme is used. Two separate reference structures, one discrete and the other analog, are used to
access a single memory area. This double mapping is described in the table below (substitute I for
input data, and Q for output data where the # symbol appears).

Global data output references, %GQnnnn and %GAQnn, can appear only in a Genius Internal
connection, because they pertain only to the C400 Controller itself. The input references,
%GInnnn and %GAInn, can appear in any Genius connections except the Genius internal
connection.
