Insufficient configuration data (Fault code 3, argument 1)

What does BUS-LED 3-1 mean?

The Fieldbus Coupler has insufficient configuration data, most likely because an I/O module was overlooked during the configuration process. This prevents the coupler from fully recognizing and operating all connected modules, leading to incomplete system functionality.

• A specific I/O module was omitted from the configuration
• The loaded configuration data is incomplete for the physically connected modules

Click steps to track your progress.

1. 1

   Check the configuration to verify all physical modules are included.

2. 2

   Load the corrected configuration onto the coupler.

3. 3

   Cycle the supply voltage of the coupler (off then on again) to restart.
