This function needs to be implemented in the dedicated driver. This function enables the actual IMD device to start the insulation measurement. Functionality need to be fullfilled after one call.

Returns
IMD_FSM_STATE_RUNNING if startup has been completed. Returns IMD_FSM_STATE_ERROR if an error is detected that prohibits a working IMD driver.

Here is the call graph for this function:

◆ IMD_ProcessInitializationState()

IMD_FSM_STATES_e IMD_ProcessInitializationState ( void  )

Processes the initialization state.

This function needs to be implemented in the dedicated driver. This function initializes the required SW modules and peripherals but does not start the actual IMD measurement.

Returns
IMD_FSM_STATE_INITIALIZATION if initialization not fininished and another call is required. IMD_FSM_STATE_IMD_ENABLE if initialization is finished and IMD_FSM_STATE_ERROR if an error is detected that prohibits a working IMD driver.

Here is the call graph for this function:

◆ IMD_ProcessRunningState()

IMD_FSM_STATES_e IMD_ProcessRunningState ( DATA_BLOCK_INSULATION_MONITORING_s pTableInsulationMonitoring)

Processes the running state.

This function needs to be implemented in the dedicated driver

Parameters
pTableInsulationMonitoringpointer to insulation monitoring database entry
Returns
IMD_FSM_STATE_RUNNING if measurement works as expected, otherwise IMD_FSM_STATE_ERROR if an error is detected that prohibits a further execution of the IMD driver.

Here is the call graph for this function:

◆ IMD_ProcessShutdownState()

IMD_FSM_STATES_e IMD_ProcessShutdownState ( void  )

Processes the shutdown state.

This function needs to be implemented in the dedicated driver. This function disables the actual IMD device to stop the insulation measurement.

Returns
IMD_FSM_STATE_SHUTDOWN if shutdown state is not fininished and another call is required. IMD_FSM_STATE_IMD_ENABLE if shut down has been completed and IMD_FSM_STATE_ERROR if an error is detected that prohibits a working IMD driver.
