Error-response parameters

This parameter describes the response of the bus coupler in the absence of EtherNet/IP
communication. You can set the following responses:
Switch off all outputs (bit 1 of the parameter byte = 0)
Maintain all outputs (bit 1 of the parameter byte = 1)
This parameter describes the response of the bus coupler in the event of a backplane malfunction.
You can set the following responses:
Option 1 (bit 2 of the parameter byte = 0):
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. It sends the diagnostic message that the backplane is attempting re-initialization.
– 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 continues to send the diagnostic message to the
controller that the backplane is attempting re-initialization, and the initialization is restarted.
LED IO/DIAG continues to flash red.
Option 2 (bit 2 of the parameter byte = 1)
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.

Bus coupler diagnostic data

5.6.1

Structure of the diagnostic data

The bus coupler sends 8 bytes of diagnostic data which is appended to the module input data. A valve
system consisting of a bus coupler and a module with 2 bytes of input data thus has a total of
10 bytes of input data. A valve system consisting of a bus coupler and a module without input data
has a total of 8 bytes of input data.
The 8 bytes of diagnostic data contain
2 bytes of diagnostic data for the bus coupler and
6 bytes of group diagnostic data for the modules.
The diagnostic data is organized as shown in Table 14.
