Module Recoverable Fault / Firmware Update / Connection Timeout

What does MOD Indicator Flashing Red mean?

The Module Status Indicator (MOD) flashes red, indicating one of several conditions: a module firmware update in progress, a failed firmware update attempt, a recoverable fault, or a connection timeout to the module. Module operation may be interrupted.

• A firmware update is currently being applied to the module.
• A previous attempt to update module firmware failed.
• The module has detected a recoverable fault condition (e.g., minor internal issue, configuration error).
• The connection from the controller to the module has timed out due to communication loss (e.g., network cable failure).

Click steps to track your progress.

1. 1

   If a firmware update is in progress, allow the update process to finish. Do not interrupt power.

2. 2

   If a firmware update failed, attempt the firmware update again following proper procedures.

3. 3

   To clear a recoverable fault, cycle module power or click 'Reset Module' on the Module Info page in Studio 5000 Logix Designer.

4. 4

   View the 'Connection page' in Studio 5000 Logix Designer to determine if a connection timeout occurred and investigate physical causes such as a damaged Ethernet cable.
