The Run indicator will flash. The Coll LED also may flash, indicating that collisions
are occurring on the Ethernet network. Such collisions are normal.

If a fault has occurred, the normal LEDs may be extinguished or other indicators
may light. This section will discuss errors reported by the Active, Ready, Coll,
Link, Kernel, Appl
and Fault indicators.

For each type of error, try the suggested remedies in the order given. If no remedy
suggested here overcomes the error, consult your Schneider Automation customer
representative.

Certain error codes are recorded in the MSTR block. For instructions on how to
read and interpret those codes through Modsoft, please refer to MSTR Function
Error Codes on page 28.

6.1.2

Active LED

If the Active LED fails to light, the module is not communicating with the
backplane.

Troubleshooting

1.

Make sure the Ethernet web embedded server module and the controller are
installed properly. Verify that the controller is functioning.

If the controller is not functioning, replace it. If neither the new controller nor the
Ethernet module will function, replace the backplane.

2.

Make sure that no more than two network option modules -- including NOE,
NOM, NOP and CRP 811 modules -- have been installed in the backplane with
a 140 CPU 113 or 213; no more than six network option modules with a 140
CPU 424, 434 or 534.

3.

Check the version of the controller executive. You must have version 1.1 or
greater to support the Ethernet web embedded server module. Earlier versions
do not recognize the module.

4.

Replace and return the faulty Ethernet web embedded server module.

6.1.3

Ready LED

If the Ready LED fails to light, the module has failed internal diagnostic tests.

Troubleshooting

1.

Make sure that power has been applied to the backplane.

2.

Replace and return the faulty Ethernet web embedded server module.
