15.2.1 Progression of Blink Sequence
An error is always displayed as three blink sequences in a cyclic manner:
1. The first blink sequence (flickering) introduces the error message.
2. After a short break, the second blink sequence starts. The number of blink
pulses indicates the exact error code that describes the type of error.
3. After another break, the third blink sequence starts. The number of blink
pulses indicates the error argument, which provides additional descriptions
of the error, e.g. on which of the 750 Series components connected to the
I/O-IPC the error has occurred.
