This button attempts to set the EtherCAT device to the Init state.
This button attempts to set the EtherCAT device to the pre-operational state.
This button attempts to set the EtherCAT device to the operational state.
This button attempts to set the EtherCAT device to the Bootstrap state.
This button attempts to set the EtherCAT device to the safe-operational state.
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.
