Redundant I/O System Diagnostics
Diagnostic Features
Many of the diagnostic functions that are associated with an analog module
are provided by proxy by the adapter. These tables summarize the functions
for each module type.

Table 49 - 1715-AENTR Adapter Diagnostic Features
Feature
Description
Redundancy level
Duplex only.
Redundancy status
The status of each module of a duplex pair is available in the input tag.
Communication diagnostics
Various communication diagnostic information is available through the input tag. For each
physical Ethernet port, this includes: Link status, duplex setting, speed, and auto-
negotiation status. For the module, this includes: CIP on EtherNet/IP timeout count, CIP on
EtherNet/IP connection count, CIP on EtherNet/IP network Lost Packets count, TCP
Connection count, and CPU utilization.
Table 50 - 1715-IB16D Module Diagnostic Features
Feature
Description
Redundancy level
Simplex or duplex.
Redundancy status
The status of each module of a duplex pair is available in the input tag.
Change of state transport
The connection trigger for the discrete modules is to be change of state.
Points that trigger production
The trigger for change of state production is selectable on a point basis for values and on a
module basis for diagnostics.
Open wire detection
With an appropriate end-of-line device installed and the open wire detection diagnostic is
enabled, a fault is indicated when an open wire condition is detected. The fault indication is
reset when the open wire condition no longer exists. Open wire detection can be disabled to
prevent unused points from indicating faults.
Short circuit detection
With an appropriate end-of-line device installed and the short circuit detection diagnostic
is enabled, a fault is indicated when a short circuit is detected. The fault indication is reset
when the short is removed.
Overload protection
User-serviceable fuses are included in the termination assembly.
Diagnostic latch
When latching is enabled, diagnostic alarms are latched until they are reset. This aids in
detecting intermittent issues. For input modules, latch reset occurs only through
messaging.
Configurable thresholds
To allow flexibility in the use and choice of end-of-line devices, you can select the
thresholds for detection of inputs, short circuits, and open wires.
