title: Get CAN signal from database by its name in CAPL
body: <p>I developped an user interface for simulating different types of failures on CAN signals contained in a frame (clock stuck, erroneous CRC). I need also to simulate unavailable values but in order to do so I have to use the input from the user which represents the signal name. </p>
  
  <p>I don't know how to look in the database and retrieve the corresponding CAN signal in order to give it the unavailable value.</p>
