14.4 Error Messages from the Fieldbus Coupler via LED
Signals
Error messages or warnings from the fieldbus coupler are displayed in
WAGOframe. They are also displayed via the CS LED (21) as a blink code.

An error is always displayed as three blinking sequences in a cyclic manner:
1. The first blinking sequence indicates the group number.
The starting point in identifying the error is the group number, from which
the error groups can be determined. The number of blink pulses indicates
the specific error group.
Example:
Group number 1: Group of
2. After a short pause, the second blinking sequence appears and indicates the
error code. The number of blink pulses indicates the specific error code that
describes the type of error.
Example:
Error code 5: S-BUS terminator not attached to last I/O module.
3. After another pause, the third blinking sequence appears and indicates the
error argument. The number of blink pulses indicates the error argument,
which provides supplemental descriptions of the error; for example, on
which of the 767 components an error is present.
Example:
Entry 0 ... 63: In which of the connected I/O modules this error has arisen.
For example, if "5" is indicated in the blink code, the error arose in the fifth
I/O module (the "0" denotes the digital inputs of the fieldbus coupler)
The group number, error code and error argument are displayed as blink codes
that are to be converted into numbers. The blink code can display numbers with
single, double or triple digits. A zero is always expressed in four cycles of 20 Hz;
zeroes preceding a digit(s) are ignored.
