5.9 EBus Error Behaviour
Fig. 26: The parameter "EBus error behavior"
This parameter is used to set the reaction to an EtherCAT 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Legacy Output data is still written, input data is frozen and therefore no longer
current.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).
Activation of EtherCAT following an EtherCAT error
Information about the EtherCAT state can be obtained in the DAP via the DWord "Status". As soon as an
error is detected in the EtherCAT network, the bit
EcFrameError is set (in the High Word Bitoffset x.2). If the
error has been rectified and the EP9300-0022 is ready once again to start the EtherCAT communication, the
bit
EcFrameError is reset and the flag NeedEBusReset is set in the High Word Bitoffset x.4.
Fig. 27: Flag NeedEBusReset
The reset is issued via Record Data Write and is structured as follows.
Profinet Record Data (Write Request) Value Meaning
Slot 0 Slot number
SubSlot 1 Sub slot number
Index 0x2013 Index Reset
Length 2 Data length
Data 0x1234 Value
Once the reset has been issued, the bit NeedEBusReset is reset.
