Error-Response Parameters - Aventics Ethernet POWERLINK Description Du Système Et Notice D'emploi

AVENTICS | Bus Coupler AES/Valve Driver AV, Ethernet POWERLINK | R412018143–BAL–001–AF
Response to an interruption
in Ethernet POWERLINK
communication
Response to a backplane
malfunction
The parameters and configuration data are not saved locally by the bus coupler. They must
be sent from the PLC to the bus coupler and the installed modules on startup.
The query "Parameter lesen" (read parameters) takes a few milliseconds since this process triggers
the internal call "Parameter vom Modul neu einlesen" (read in parameters from module again).
The most recently read-out data is transferred.
Thus, execute the query "Parameter lesen" (read parameters) twice in 1 s intervals to read out
the current parameter data from the module.
If you only execute the query "Parameter lesen" once, in the worst case, the parameters that were
read in the last time the device was restarted will be returned.

Error-response parameters

This parameter describes the response of the bus coupler in the absence of Ethernet POWERLINK
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 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 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.
