FUNCTION accVibrationSetWakeup : INT;
VAR_INPUT
  Enable      : BOOL;
  Sensitivity : SINT := -1;
END_VAR;

INCLUDE rtcu.inc
 
PROGRAM test;
// These are the local variables of the program block
VAR
  wk    : DINT;
END_VAR;
// The next code will only be executed once after the program starts
  ...
  // Enable wake on vibration with high sensitivity
  accVibrationSetWakeup(sensitivity := 80, enable := ON);
  ...

  // Sleep 600 seconds or wake on vibration detection
  wk := pmSuspend(time:=600, mode := 0);
  ...
BEGIN
// Code from this point until END will be executed repeatedly
END;
END_PROGRAM;
