ETHERNET TCP/IP
‘USR‘-LED
The state of the ‘USR‘ LED is programmable with WAGO-I/O-PRO CAA.
Functions in the program library ”Visual.lib“ can be used to control the LED
state. One of the many possible uses of this LED is to indicate the
RUN/STOP state of your controller.
Fault code 11: "Gateway-/Mailbox I/O module fault"
Fault argument
* The number of blink pulses (n) indicates the position of the I/O module. I/O modules
without data are not counted (e.g. supply module without diagnosis)
Example: The 13th I/O module has been removed.

3.
The I/O-LED starts the fault display with the first blink sequence (approx. 10 Hz).
The second blink phase (approx. 1 Hz) follows the first pause. The I/O-LED blinks
four times and thus signals the fault code 4 (internal bus data fault).
The third blink sequence follows the second pause. The I/O-LED blinks twelve times.
The fault argument 12 means that the internal bus is interrupted after the 12
module.
