12.5.1 The EtherCAT bus does not assume the "Pre-Operational" state.

During the start-up of the EtherCAT bus, a check is carried out at the transition from "Init" to "Pre-

Operational" to determine whether the physical bus configuration corresponds to the bus

configuration configured. If theses configurations are different, the master does not enter the "Pre-

Operational" state.

Furthermore, the slaves are initialised during the transition from "Init" to "Pre-Operational". If this

fails because, for instance, a slave denies the configuration, the master does not enter the "Pre-

Operational" state.

Cause Faulty bus configuration and bus structure

• Slaves are missing.

• Slaves have been inverted or their configuration is faulty.

• A wrong slave type has been configured or is at the fieldbus.

• The inputs and outputs of the EtherCAT communication module are reversed (IN/OUT

connections).

•Faulty wiring

Error message EtherCAT_Master: Start master failed. Bus mismatch

...

Lenze_EPM_T130_V10_18 (1002): Configuration mismatch. Check VendorID failed (0x3B /

missing )

Remedies Correct the bus configuration or the physical bus structure.

Afterwards, reload the »PLC Designer« application into the automation system.

Cause Wiring error: EtherCAT cable is not connected to the master.

Error message EtherCAT_Master: Start master failed. EtherCAT cable disconnected

Remedies Correct wiring.

Afterwards, reload the »PLC Designer« application into the automation system.
