Diagnostics Messages via Flashing Sequences

11.2.1

Flashing Sequences

A diagnosis (fault/error) is always displayed as three flashing sequences in a
cyclic manner:
1. The first flashing sequence (flickering) initiates reporting of the fault/error.
2. After a short break (approx. 1 second), the second flashing sequence
starts. The number of blink pulses indicates the error code, which
describes the type of error involved.
3. After a further break the third flashing sequence is initiated. The number of
blink pulses indicates the error argument, which provides an additional
description of the error, e.g., which of the I/O modules connected to the
controller exhibits an error.
