The 1747-AENTR adapter supports up to five Listen Only connections
per SLC module.

Module Keying

Missing or misplaced modules are detected if the module in question is
configured with RSLogix 5000 or Logix Designer application as an individual
module connection and “compatible module” is selected for electronic keying. If
a module connection is attempted to a module which is a missing or misplaced
module, the connection will fail.

Output Operation During Fault and Idle Modes

RSLogix 5000 or Logix Designer application allows configuration to characterize
each module connection activity during certain operational states.

During idle mode and fault modes, outputs are configured for one of the
following operation states:

IMPORTANT

When a Listen Only connection is made, there must be an existing
Exclusive Owner or Input Only connection, the connection RPIs must
match exactly, the input chunk configuration (if any) must match exactly,
and all connections to the same module must be Multicast.

Note that changing a module connection from Input Only to Listen Only
will result to the following:

reset the RPI to 20 ms

reset the input chunk configuration (if any) to the default

set the Input Type to Unicast

TIP

All Listen Only connections are terminated when all associated
independent connections are terminated.

Output Action

Reset outputs to off

Hold last state

Write Safe State data to outputs
