# 用語(terms)

|Term|Description|
|:--|:--|
|BSW |Basic Software
|BswM |Basic Software Mode Manager
|ComM| Communication Manager
|DCM |Diagnostic Communication Manager
|Det| Default Error Tracer
|EcuM |ECU State Manager module
|I-PDU |Information Protocol Data Unit
|NM| Network Management
|PDU|Protocol Data Unit
|SW-C| Software Component
|VMM| Vehicle Message Matrix
|OA TC10| Open Alliance TC10 specification (see [33])
|IRA |Internal Request Array. This is a bit vector which contains the aggregated internal PNC requests per channel. (see also chapter 8.6.2 “Nm_UpdateIRA”)
|EIRA |External and Internal Request Array. This is a bit vector which contains the aggregated external and internal PNC requests
|ERA| External Request Array. This is a bit vector which contains the aggregated external PNC requests. Each ComMChannel which has a ComMGatewayType set is has one corresponding ERA
|ERAn| All External Request Arrays which are available in ComM, i.e. “n” ComMChannels were ComMGatewayType is set, result in “n” External Request Arrays in ComM
|DCM_ActiveDiagnostic indication|The DCM module indicates an active diagnostic session. DCM need “full communication” = COMM_FULL_COMMUNICATION for diagnostic purpose
|Active wake-up| Wake-up caused by the hosting ECU e.g. by a sensor.
|Application signal scheduling |Sending of application signals according to the VMM. Scheduling of CAN application signals is performed by the Communication Module, scheduling of LIN application I-PDUs (a PDU containing signals) is performed by the LIN interface and scheduling of FlexRay application PDUs is performed by the FlexRay Interface module.
|Bus sleep| No activity required on the communication bus (e.g. CAN bus sleep).
|Bus communication messages|Bus communication messages are all messages that are sent on the communication bus. This can be either a diagnostic message or an application message.
|COM Inhibition status |Defines whether full communication, silent communication or wakeup is allowed or not.
|Communication Channel| The medium used to convey information from a sender (or transmitter) to a receiver.
|Communication Mode |Mode determining which kind of communication are allowed: “full communication” = COMM_FULL_COMMUNICATION “no communication” = COMM_NO_COMMUNICATION “silent communication” = COMM_SILENT_COMMUNICATION Note: COMM_SILENT_COMMUNICATION can not be requested by a user. Internal mode for synchronizing network at shutdown
|Diagnostic PDU scheduling |Sending of diagnostic PDUs. Scheduling of CAN diagnostic PDUs is performed by the diagnostic module, scheduling of LIN diagnostic PDUs is performed by the diagnostic module and the LIN interface and scheduling of FlexRay diagnostic PDUs is performed by the diagnostic module and the FlexRay Interface module.
|ECU shut down |See ECU State Manager specification [6].
|Fan-out |Same message/indication are sent to multiple destinations/receivers
|Independent software component|A separately developed software component performing a coherent set of functions with a minimum amount of interfaces to other software applications on an ECU. This can be e.g. a basic software component or an application software component.
|Passive wake-up |Wake-up by another ECU and propagated (e.g. by bus or wake-upline) to the ECU currently in focus.
|System User |An administration functionality (a specific "user", which is generated within the internal context of the ComM) for making a default request and for overriding the user requests.
|User |Concept for requestors of the ECU State Manager module and of the Communication Manager Module. A user may be the BswM, a runnable entity, a SW-C or a group of SW-Cs, which act as a single unit towards the ECU State Manager module and the Communication Manager Module.
|User Request |A User can request different Communication Modes from ComM
|Managed channel |A ComM channel that is referenced exclusively from one other channel by ECUC parameter ComMManageReference (see ECUC_ComM_00893).
|Managing channel| A ComM channel that references 1..n other channels by ECUC parameter ComMManageReference (see ECUC_ComM_00893).
