Troubleshooting 7-3
Understanding the SCANport LED When viewing the SCANport LED, the color and status (solid or
flashing) of the LED are significant. Refer to this table.
LEDs Viewed: If: Cause: Action:
SCANport
Solid red Either the SCANport interface is not connected
to a SCANport product, or it is connected but for
some reason has not detected a valid SCANport
ID. 1. Verify the SCANport product is powered.
2. Check media for broken cables, loose
connectors, etc.
Flashing red The SCANport interface has detected an error,
such as no communications from the SCANport
product or a datalink is configured in the module
and your product does not support it or another
adapter is using it. 1. Temporarily disconnect the cable to the
SCANport product and then reconnect it.
2. Verify the module’s configuration works with
the product’s configuration.
3. Power cycle or reset the module or the
SCANport product.
Solid orange A SCANport compatibility problem exists. Contact Rockwell Automation support.
Solid green The SCANport interface is fully functional for
both messaging and control I/O. The adapter is
communicating normally with the connected
SCANport product. None
Flashing green A valid SCANport ID has been detected and
messages are being received from the
SCANport product. The module has not been
configured for control I/O messages to the
SCANport product. This indicates that the
SCANport interface is in a messaging-only
mode and no I/O enables are present in the
current configuration. If control I/O communication is desired,
configure the module’s parameters to enable
control I/O.
