Comissioning/Configuration
Table 8: State Machine
Init This button attempts to set the EtherCAT device to the Init state.
Pre­Op This button attempts to set the EtherCAT device to the pre­operational state.
Op This button attempts to set the EtherCAT device to the operational state.
Bootstrap This button attempts to set the EtherCAT device to the Bootstrap state.
Safe­Op This button attempts to set the EtherCAT device to the safe­operational state.
Clear Error This button attempts to delete the fault display. If an EtherCAT slave fails during change
of state it sets an error flag.
Example: An EtherCAT slave is in PREOP state (pre­operational). The master now
requests the SAFEOP state (safe­operational). If the slave fails during change of state it
sets the error flag. The current state is now displayed as ERR PREOP. When the Clear
Error button is pressed the error flag is cleared, and the current state is displayed as
PREOP again.
Current State Indicates the current state of the EtherCAT device.
Requested State Indicates the state requested for the EtherCAT device.
DLL Status
Indicates the DLL status (data link layer status) of the individual ports of the EtherCAT slave. The DLL status
can have four different states:
Status Description
No Carrier / Open No carrier signal is available at the port, but the port is open.
No Carrier / Closed No carrier signal is available at the port, and the port is closed.
Carrier / Open A carrier signal is available at the port, and the port is open.
Carrier / Closed A carrier signal is available at the port, but the port is closed.

Note
Parameterization
Terminals' parameterization will be conducted by the CoE tab (double­click on the referring
object) or the Process data tab (PDO assignment)

EtherCAT XML Device Description
The description correspond to the display of the CoE objects from the EtherCAT XML De­
vice Description. It is strongly recommended to download the latest revision of the corre­
sponding XML file from the Beckhoff website (http://www.beckhoff.com/english/default.htm?

Introduction
The CoE overview contains objects for different intended applications:
• Objects required for parameterization [ } 114] during commissioning
• Objects intended for regular operation [ } 116], e.g. through ADS access
• Objects for indicating internal settings [ } 117] (may be fixed)
• Further profile‐specific objects [ } 134] indicating inputs, outputs and status information
