Fig. 37: The parameter EBus error behavior
This parameter is used to set the response to an E-bus error. The following options are available:
Legacy
Output data is still written, input data is frozen and therefore no longer
current.
Set IOs to 0
Output data is written to zero; input data is written to zero; when the E-
bus is error-free, it automatically starts the data exchange.
Set IOs to 0 without EBus restart
(Default setting)
Output data is written to zero; input data is written to zero; when the E-
bus is error-free, it can be activated again via the record data (see
below).
Activating the E-bus after an E-bus error
In the DAP, information about the E-bus is provided via the status DWord. When an error occurs in the E-
bus, the bit
EcFrameError
is set (in the high word bit offset x.2). Once the error has been rectified and the
coupler is ready to restart the E-bus, the bit
EcFrameError
is reset and the flag
NeedEBusRese
is set in the
high word bit offset x.4.
