The coupler starts after switching on the supply voltage. The "I/O" LED flashes red. Following a fault free run up the "I/O" LED changes to green steady light.
In the case of a fault the "I/O" LED continues blinking red. The fault is cyclically displayed with the blink code.

Example: the 13th I/O module is removed.
1.The "I/O" LED generates a fault display with the first blink sequence (approx. 10 Hz).
2.The first pause is followed by the second blink sequence (approx. 1 Hz). The "I/O" LED blinks four times and thus signals the fault code 4 (internal bus data fault).
3.The third blink sequence follows the second pause. The "I/O ERR" LED blinks twelve times. The fault argument 12 means that the internal bus is interrupted after the 12th I/O module.

3.1.11Fault behaviour
3.1.11.1Fieldbus failure
A fieldbus failure has occurred when the master is switched off or the bus cable is interrupted. A fault in the master can also lead to a fieldbus failure.
The red "BF" LED lights up.
The failure of the fieldbus can activate the parameterisable substitute value of the I/O modules. During projecting of the inputs and outputs a substitute value can be laid down for each channel.

Behaviour determined by I/O module |
|
|
|
|
The value is entered in the output process image by the coupler. With I/O modules with byte orientated data width, e.g. the pulse width module, the substitute value is determined via the value area.
As soon as the fieldbus is active the process data is transmitted and the output correspondingly set in the nodes.
