Power-up LED Patterns

At power-up, the LEDs show the blink patterns described below. The LEDs also blink diagnostic patterns for
certain operating errors and for module identification. See Chapter 5, Diagnostics for a description of those
special blink patterns.
Step LED/Blink pattern
1 All LEDs OFF
1.1 ACTIVE LED solid green
(PNC001-Bxxx only)
1.2 CONFIG LED solid green
(PNC001-Bxxx only)
2 STATUS LED solid green
OK LED blinks Amber with
special blink code
OK, LAN, and STATUS LEDs
blink green in unison (1 Hz)
3 LAN and STATUS LED solid

Note: Under certain ambient operating temperatures, the PROFINET Controller may momentarily display
the overtemperature pattern during power up, while it is calibrating its thermal protection functions.
This indication may be ignored, and no overtemperature entry is added to the Local Log table, the
Controller Fault Table or I/O Fault Table.
For details, see Special LED Blink Patterns in Chapter 5, Diagnostics.
