title: CAN Communication: Knowing Which Node Transmitted Data
body: <p>I am new to CAN communication and one of my tasks is to use a CANalyzer to learn what message IDs are being used for a product and what data is being sent/received.</p>
  <p>The product has multiple nodes that can send/receive CAN messages. I know CAN messages are broadcasted to all the nodes, but the part I'm having a hard time determining is which node transmitted the message and which nodes received it.</p>
  <p>So, for example, if I have 3 CAN nodes, is there a way I can determine that Node 1 sent the message and Node 2/3 are receiving the message?</p>
  <p>Thank you in advance.</p>
