OnMostMHPError

Valid for: CANoe DE Note
OnMostMHPError can only be used in the Measurement Setup and should be inserted under the item “Callback function”.
For simulation of a MOST High connection sender and receiver in CAPL, the MOST High DLL can be used. The DLL is located in the Exec32 folder of the MOST High Demos.

​
Function Syntax

long OnMostMHPError(long sourceDevID, long destDevID, long fBlockID, long instID, long functionID, long opType);

​
Description

The event procedure is called up as soon as a MOST High protocol violation is observed. Within this event procedure the following functions are available:
  • long mostMHPErrorCode() Indicates the MHP observer error number. See possible MHP observer error codes. Parameter:
    None
    Returns:
    Observer error number
  • long mostMHPErrorValue() Indicates the error value. Not supported by all error codes. Parameter:
    None
    Returns:
    Error value or 0
  • long mostMHPErrorExpectedValue() Indicates the expected value. Not supported by all error codes. Parameter:
    None
    Returns:
    Expected value or 0
  • long mostMHPErrorIsWarning() Indicates if this is a warning. Warnings may indicate a communication problem. Parameter:
    None
    Returns:
    Error value or 0
The functions mostEventChannel, mostEventTime and mostEventTimeNS can be used to call up supplemental information.

​
Parameters

  • sourceDevID: Address of the transmitter
  • destDevID: Address of the receiver
  • fBlockID: FBlockID of the receiver
  • instID: Instance ID of the receiver
  • functionID: FunctionID of the receiver
  • opType: OpType of the receiver

​
Return Values

The return value determines whether the MHP error event is relayed to the next function block in the Measurement Setup (e.g., a Trace Window).
  • 0: No relay
  • 1: Relay
