H
Combine 92S16 pattern generation modules with up to seven 92S32 modules.
H
Combine up to eight 92S32 modules.
There are some limitations when working with variable width modules. For
example, 92A60 and 92A90 modules cannot be combined. Also, modules can only
be combined with other modules in the same mainframe and must reside in adjacent
slots; you cannot combine modules that reside in different mainframes.
Combined modules function in parallel; they are started and stopped as a unit.
For example, when a 92A16 and five 92A16Es are combined, they function
together as a single acquisition module that is 96 channels wide. When eight
92S32s are combined, they function together as one 256-channel-wide pattern
generation module.
These functional groupings of similar modules, called module formations, are
automatically created based on the card/slot configuration of your mainframe. A
module formation is a functional grouping of variable-width modules of similar
types that reside in adjacent mainframe slots. Based on the card/slot configuration of
your mainframe, system software automatically creates a set of module formation
selections for each module type. For example, if your mainframe contains two
92A16 cards and three 92A16E cards in adjacent slots, software establishes all valid
module combinations of that module type (there are eight in this case; each
formation is assigned a unique identification number). Each valid combination is a
module formation. For instance, formation 0 (default) might contain a single
80-channel-wide module (composed of all five cards); formation 1 might split the
five cards into one 64-channel module and one 16-channel module; formation 2
might contain one 48-channel module and one 32-channel module.
Figure 3–31 shows the process of creating variable width modules. System
software establishes all valid combinations of modules, or module formations,
that can be formed from each card type in the mainframe (assuming all cards of a
type are located in adjacent mainframe slots). An identification number is
assigned to each module formation; you select the formation, by number, that
best suits your application.
