Error-response parameters

This parameter describes the response of the bus coupler in the absence of PROFIBUS DP
communication. You can set the following responses:
Switch off all outputs (presetting)
Maintain all outputs
This parameter describes the response of the bus coupler in the event of a backplane malfunction.
You can set the following responses:
Option 1 (default setting):
If there is a temporary backplane malfunction (triggered, e.g., by a spike in the power supply),
the IO/DIAG LED flashes red and the bus coupler sends a warning to the controller. As soon
as the communication via the backplane is reinstated, the bus coupler returns to normal mode
and the warnings are canceled.
In the event of a sustained backplane malfunction (e.g. due to the removal of an end plate),
the IO/DIAG LED flashes red and the bus coupler sends an error message to the controller.
The bus coupler simultaneously resets all valves and outputs. The bus coupler tries
to re-initialize the system.
– If the initialization is successful, the bus coupler resumes its normal operation. The error
message is canceled and the IO/DIAG LED is illuminated in green.
– If the initialization is not successful (e.g. due to the connection of new modules to the backplane
or a defective backplane), the bus coupler sends the error message "Backplane initialization
problem" to the controller and the initialization is restarted. LED IO/DIAG continues to flash
red.
Option 2
For temporary backplane malfunctions, the response is identical to option 1.
In the event of a sustained backplane malfunction, the bus coupler sends an error message
to the controller and the IO/DIAG LED flashes red. The bus coupler simultaneously resets all
valves and outputs. An initialization of the system is not started. The bus coupler must
be restarted manually ("power reset") in order to return it to normal mode.

Transferring the configuration to the controller

Data may be transferred to the controller once the system is completely and correctly configured.
1. Make sure that the controller parameter settings are compatible with those of the valve system.
2. Establish a connection to the controller.
3. Transfer the valve system data to the controller. The precise process depends on the PLC
configuration program. Observe the respective documentation.
