Preparing the Flash File System

The flash file system must be prepared in order to use the Web interface of the
fieldbus controller to make all configurations.
The flash file system is already prepared when delivered.
However, if the flash file system has not been initialized on your fieldbus
controller or it has been destroyed due to an error, you must first extract it to the
flash memory to access it.
Do not connect Communication Cable when energized!
To prevent damage to the service interface, do not connect or disconnect 750-
920 respectively 750-923 Communication Cable when energized! The fieldbus
coupler/controller must be de-energized!
Resetting erases data!
Note that resetting erases all data and configurations.
Only use this function when the flash file system has not been initialized yet or
has been destroyed due to an error.
1. Switch off the supply voltage of the fieldbus controller.
2. Connect the communication cable 750-920 or 750-923 respectively the
Bluetooth
controller and to your computer.
3. Switch on the supply voltage of the fieldbus controller.
After the power is switched on, the fieldbus controller is initialized. The fieldbus
controller determines the I/O module configuration and creates a process image.
During startup, the I/O LED (red) will flash. After a brief period, the I/O LED lights
up green, indicating that the fieldbus controller is operational.
If an error occurs during start-up indicated by the I/O LED flashing red, evaluate
the error code and argument and resolve the error.
More information about LED signaling
The exact description for evaluating the LED signal displayed is available in the
section "Diagnostics" > ... > "LED Signaling".
4. Start the "WAGO Ethernet Settings" program.
