ChkStart_LINRespToleranceViolation

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

  • dword ChkStart_LINRespToleranceViolation (Message Frame, float Tolerance);
  • dword ChkStart_LINRespToleranceViolation (Node ObservedNode, float Tolerance);
  • dword ChkStart_LINRespToleranceViolation (Message Frame, float Tolerance, char[] CaplCallback);
  • dword ChkStart_LINRespToleranceViolation (Node ObservedNode, float Tolerance, char[] CaplCallback);

​
Constructor

TestCheck::StartLINRespToleranceViolation (Message Frame, float Tolerance)
  • TestCheck::StartLINRespToleranceViolation (Node ObservedNode, float Tolerance);
  • TestCheck::StartLINRespToleranceViolation (Message Frame, float Tolerance, char[] CaplCallback);
  • TestCheck::StartLINRespToleranceViolation (Node ObservedNode, float Tolerance, char[] CaplCallback);

​
Description

Checks the LIN response transmission time. An event will be generated if the measured response transmission time is over the allowed tolerance. Note
  • This function monitors frames transmitted without a failure only.
  • Components influencing response tolerance: inter-byte space, response space.
  • For LIN 2.0 compliance, the Tolerance has to be in the range [0 .. 40]%.

​
Parameters

  • Frame: Unconditional LIN frame to verify.
  • ObservedNode: Node, whose published frames shall be verified.
  • CaplCallback: Name of CAPL callback function to be called on generated event. In simulation nodes, this parameter has to be set. In test modules, this parameter is optional.

​
Return Values

  • 0: Check could not be created and must not be referenced.
  • > 0: Check was created successfully and may be referenced using the returned (handle-) value.

Check-specific Queries

Example

...
dword checkId;
ChkConfig_SetPrecision(9); // switch to ns precision
// Create and start the check for LIN response tolerance violation in "Motor1" node
checkId = ChkStart_LINRespToleranceViolation(LIN20db::Motor1, 40.0 , "LINRespToleranceCallback");
ChkConfig_SetPrecision(3); // switch to ms precision (default)
...
// CAPL callback for violation notification
void LINRespToleranceCallback (dword aCheckId)
{
   ChkQuery_EventStatusToWrite(aCheckId);
