Special LED Blink Patterns
Multiple LEDs can blink in patterns that indicate special conditions:
LEDs Involved
Pattern Displayed
Indication
OK, FAULT,
CONNECT, LAN,
PORT 1 / PORT 2
The OK, CONNECT, FAULT, LAN, Port 1 and Port 2
LEDs flash amber once. The OK LED blinks an error
code in amber. The pattern is repeated until the module
is reset or power-cycled.
Fatal Error
See below.
PORT 2 / PORT 1,
LAN, CONNECT,
FAULT, OK
The LEDs listed at left go On (green) in order, from
bottom to top. After the top LED (OK) has been ON for
about 50 ms, the LEDs go Off from top to bottom, until all
of the LEDs are Off. After all of the LEDs have been Off
for about 50 ms, the pattern is repeated.

Fatal Error Blink Pattern
If the PROFINET Scanner detects a fatal error, it attempts to write diagnostic data to nonvolatile
storage. The OK LED fast blinks amber. If the module has been configured to blink fatal error
codes, it starts blinking the error code after writing the diagnostic data to nonvolatile storage.
The OK, FAULT, CONNECT, LAN, Port 1 and Port 2 LEDs flash amber once to indicate the
start of the error code. After a pause, the OK LED blinks a 2-digit hexadecimal error code. The
OK LED first blinks to indicate the most significant error digit, then after a one-second pause
blinks again to indicate the least significant error digit. Repetitions continue until the module is
reset or power-cycled.
Module Identification LED Pattern
The Identification LED blink pattern described above can be used to locate and/or identify a
PROFINET Scanner, for example, when assigning its Device Name. PROFICY Machine Edition
or any DCP client can be used to command the module to begin or end the blink pattern.
Firmware Update Mode Blink Patterns
Blink patterns described in the table above indicate that a firmware update of the PROFINET
scanner is underway. Because the update is being done through the USB port, the USB LED
also blinks to indicate activity on the USB port.
