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.
Description
Duplex only.
The status of each module of a duplex pair is available in the input tag.
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.
Description
Simplex or duplex.
The status of each module of a duplex pair is available in the input tag.
The connection trigger for the discrete modules is to be change of state.
The trigger for change of state production is selectable on a point basis for values and on a
module basis for diagnostics.
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.
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.
User-serviceable fuses are included in the termination assembly.
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.
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.
