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.
