Maintenance
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.
6.1.2Active 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
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.
6.1.3Ready 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.
