ID-allocation is viaWINgauge. Then the nodes can be switched directly into the Operational state. By switching a device into the stopped state itis forced to stop the communication altogether (except node guarding, if active). Furthermore, this state can be used toachieve certain application behaviour. The definition of this behaviour falls into the scope of device profiles.EEPROM Option for transition from pre-operational to operational state after KL.15on.It is possible to enable an option via EEPROM configuration, which lets CANcockpit move from pre-operational state tooperational state automatically after KL.15 is turned on. Also, if CANcockpit performs a reset, the operational state will beentered without requiring an NMT-command. A reset for example can be caused by a low voltage condition or a watchdogtrigger.However when an NMT-command is received to move from operational to another state, CANcockpit will perform therequested transition without automatically re-entering the operational mode.If the pre-operational state is entered, because of an error condition requiring this, then CANcockpit will remain in the pre-operational state without automatically moving to operational state again.Static allocation of the communication object identifiers (COB-ID's)Static distribution means that the identifiers are fixed by the module suppliers and may be changed by the system integratorthrough module specific means such as configuration with WINgauge.Restore DefaultsIf parameters in EEPROM can be changed via CANopen interface, then this option should be implemented.
