DLM5000 Mixed Signal Application Note
■The CAN bus is a standard protocol for connecting multiple electronic control systems via a data bus and is currently used in various fields such as automotive, transportation, FA and industrial equipment.
■In the CAN bus, when the data bus is free, all connected nodes can transmit data equally. If more than one node starts sending data messages at the same time, the node sending the data message with the higher priority ID acquires the transmission right. It is also possible for multiple nodes to receive data with the ID they need at the same time.
■A mechanism to prevent collisions between nodes by using IDs contained in data is called arbitration.
■In particular, as the number of ECUs in an automobile increases, it is becoming more and more important to check the operation of arbitration and to grasp the delays when gateways connecting ECUs are involved in complex situations.
