EthSM processes internal network mode state machines based on parameters provided by ComM. Depending on the state machine's transition conditions, it calls interfaces of EthIf and TcpIp to control the Ethernet controller, transceiver, and TcpIp protocol stack for managing Ethernet communication status. It then notifies ComM and BswM of the current communication mode through interfaces between them. 以太网通信状态管理功能功能实现 (Ethernet communication status management function implementation) ================================================================================================== EthSM根据以下状态机管理以太网通信状态: EthSM manages Ethernet communication states according to the following state machine: .. figure:: ../../_static/参考手册(Module_Reference_Manual)/EthSM/image2.png :alt: EthSM网络状态转换状态机 (EthSM Network Status Transition State Machine) :name: EthSM网络状态转换状态机 (EthSM Network Status Transition State Machine) :align: center 状态机包括以下几个状态: The state machine includes the following states: 1. ETHSM_STATE_OFFLINE 2. ETHSM_STATE_WAIT_TRCVLINK 3. ETHSM_STATE_WAIT_ONLINE 4. ETHSM_STATE_ONLINE 5. ETHSM_STATE_ONHOLD 6. ETHSM_STATE_WAIT_OFFLINE 状态迁移过程 (State transition process) ------------------------------------------------- 初始化后EthSM处于ETHSM_STATE_OFFLINE状态。 After initialization, EthSM is in the ETHSM_STATE_OFFLINE state. 当EthSM_RequestComMode(COMM_FULL_COMMUNICATION)被调用,EthSM调用EthIf_SetControllerMode(ETH_MODE_ACTIVE)请求EthIf将以太网控制器设置为ACTIVE模式,并调用BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_TRCVLINK)通知BswM模块。之后EthSM从ETHSM_STATE_OFFLINE迁移到ETHSM_STATE_WAIT_TRCVLINK状态。 When EthSM_RequestComMode(COMM_FULL_COMMUNICATION) is called, EthSM calls EthIf_SetControllerMode(ETH_MODE_ACTIVE) to request that the Ethernet controller be set to ACTIVE mode and calls BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_TRCVLINK) to notify the BswM module. Afterwards, EthSM transitions from ETHSM_STATE_OFFLINE to ETHSM_STATE_WAIT_TRCVLINK state. 当EthSM_TrcvLinkStateChg(ETHTRCV_LINK_STATE_ACTIVE)被调用,EthSM从ETHSM_STATE_WAIT_TRCVLINK迁移到ETHSM_STATE_WAIT_ONLINE状态。同时调用TcpIp_RequestComMode(TCPIP_STATE_ONLINE)请求将TCPIP模块将TCPIP协议栈设置到ONLINE模式,并调用BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_ONLINE)接口通知BswM模块。 When EthSM_TrcvLinkStateChg(ETHTRCV_LINK_STATE_ACTIVE) is called, EthSM transitions from ETHSM_STATE_WAIT_TRCVLINK to ETHSM_STATE_WAIT_ONLINE state. At the same time, TcpIp_RequestComMode(TCPIP_STATE_ONLINE) is invoked to request that the TCPIP module sets the TCPIP protocol stack to ONLINE mode, and BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_ONLINE) interface is called to notify the BswM module. 当EthSM_TcpIpModeIndication(TCPIP_STATE_ONLINE)被调用,EthSM从ETHSM_STATE_WAIT_ONLINE迁移到ETHSM_STATE_ONLINE模式,并调用BswM_EthSM_CurrentState(ETHSM_STATE_ONLINE)通知BswM模块,调用ComM_BusSM_ModeIndication(COMM_FULL_COMMUNICATION)通知ComM模块。 When EthSM_TcpIpModeIndication(TCPIP_STATE_ONLINE) is called, EthSM transitions from ETHSM_STATE_WAIT_ONLINE to the ETHSM_STATE_ONLINE mode and calls BswM_EthSM_CurrentState(ETHSM_STATE_ONLINE) to notify the BswM module, and calls ComM_BusSM_ModeIndication(COMM_FULL_COMMUNICATION) to notify the ComM module. 当EthSM_RequestComMode(COMM_NO_COMMUNICATION)被调用,EthSM调用TcpIp_RequestComMode(TCPIP_STATE_OFFLINE)请求TcpIp模块将TCPIP协议栈设置为OFFLINE模式,并调用BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_OFFLINE)通知BswM模块。之后EthSM从ETHSM_STATE_ONLINE迁移到ETHSM_STATE_WAIT_OFFLINE状态。 When EthSM_RequestComMode(COMM_NO_COMMUNICATION) is called, EthSM calls TcpIp_RequestComMode(TCPIP_STATE_OFFLINE) to request the TcpIp module to set the TCPIP protocol stack to OFFLINE mode and calls BswM_EthSM_CurrentState(ETHSM_STATE_WAIT_OFFLINE) to notify the BswM module. Afterward, EthSM transitions from ETHSM_STATE_ONLINE to ETHSM_STATE_WAIT_OFFLINE state. 当EthSM_TcpIpModeIndication(TCPIP_STATE_OFFLINE)被调用,EthSM从ETHSM_STATE_WAIT_OFFLINE迁移到ETHSM_STATE_OFFLINE状态。并调用EthIf_SetControllerMode(ETH_MODE_DOWN)请求EthIf将以太网控制器设置为DOWN模式,并调用BswM_EthSM_CurrentState(ETHSM_STATE_OFFLINE)通知BswM模块,调用ComM_BusSM_ModeIndication(COMM_NO_COMMUNICATION)通知ComM模块。 When EthSM_TcpIpModeIndication(TCPIP_STATE_OFFLINE) is called, EthSM transitions from ETHSM_STATE_WAIT_OFFLINE to the ETHSM_STATE_OFFLINE state. It then calls EthIf_SetControllerMode(ETH_MODE_DOWN) to request that the Ethernet controller be set to DOWN mode, and calls BswM_EthSM_CurrentState(ETHSM_STATE_OFFLINE) to notify the BswM module, and calls ComM_BusSM_ModeIndication(COMM_NO_COMMUNICATION) to inform the ComM module. 状态对照表 (State Comparison Table) ------------------------------------------------- EthSM各状态下以太网控制器,收发器,TCPIP与ComM状态对照表: Ethernet controller, transceiver, TCP/IP, and ComM status对照 table for EthSM in various states: .. figure:: ../../_static/参考手册(Module_Reference_Manual)/EthSM/image3.png :alt: EthSM状态对照表 (EthSM Status Table) :name: EthSM状态对照表 (EthSM Status Table) :align: center 源文件描述 (Source file description) =============================================== .. centered:: **表 EthSM组件文件描述 (Table Descriptions of EthSM Component Files)** .. list-table:: :widths: 50 50 :header-rows: 1 * -
