State Machine
Init This button attempts to set the EtherCAT device to the Init state.
Pre-Op This button attempts to set the EtherCAT device to the pre-operational 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.
Safe-Op This button attempts to set the EtherCAT device to the safe-operational 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 (pre-operational). The master now
requests the SAFEOP state (safe-operational). 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:
