module with failed hardware. For critical processes, the redundant DO
with read-back capability is recommended.
Use the same DO module type in any redundant pair; do not install a
DO with read-back module in the primary controller and a standard
DO module as its redundant counterpart in the backup controller, or
vice versa.
See Software Configuration later in this section for details on setting
up DO with readback.
Wiring the Module
Figure 3-11 shows field wiring assignments associated with a locally
terminated DO module; Figure 3-12 shows a wiring diagram for the
DO. Field wiring assignments associated with remotely terminated DO
modules. Figure 3-13 shows field wiring assignments for a remotely
terminated DO module. Figure 3-14 shows a special remote
termination module with built-in discrete relay modules.
