Redundant I/O System Diagnostics
Diagnostic Features Many of the diagnostic functions 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 Module 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 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 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, the thresholds for detection of inputs,
short circuits, and open wires are user selectable.
