Testing the Function of the Fieldbus Node

More information about reading the IP address
You can use "WAGO Ethernet Settings", button [Identify], via Service Interface
to read the IP addresses currently assigned.
1. To ensure that the IP address is correct and to test communication with the
fieldbus node, first turn off the operating voltage of the fieldbus node.
2. Create a non-serial connection between your client PC and the fieldbus
node.
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".
3. To test the coupler's newly assigned I/P address, start a DOS window by
clicking on the Start menu item Programs/MS-DOS Prompt.
4. In the DOS window, enter the command: "ping " followed by the IP address
of your coupler in the following format:
ping

5. When the [Enter] key has been pressed, your PC will receive a query from
the coupler, which will then be displayed in the DOS window.
If the error message: "Timeout" appears, please compare your entries
again to the allocated IP address and check all connections.
