For example, a 2 setting of S2 (2 x 16 = 32) and an A setting of S1 (10) gives
a module a logical (decimal) address of 42, the decimal equivalent of the
hexadecimal word 2A formed by the switch setting.
Module addressing is completely independent of module physical locations.
Each module address must be different from all other module addresses in
the system. Addresses are determined by the system designer during system
planning.
Backup Configuration Options
Three input/output configuration options are available: shared, redundant, and
mixed.
Shared Configuration
A shared I/O configuration uses a primary DPU, a secondary DPU, and one set
of Model IOP parallel modules. See Figure 1-6. Both DPUs share the I/O bus
but only the active DPU (primary or secondary) receives data from, and sends
data to, the set of common I/O modules.
