The Controller Area Network (CAN) is a serial communication way, which efficiently supports distributed real-time control with a very high level of security. It provides the error process mechanisms and message priority concepts. These features can improve the network reliability and transmission efficiency. Furthermore, CAN supplies the multi-master capabilities, and is especially suitable for networking intelligent devices as well as sensors and actuators within a system or sub-system.

The PM-213X-CAN series power meter provides the CAN bus interface for users to easily gather the real-time power consumption information in their CAN applications. The PM-213x-CAN provides the Auto-Response mode which responses messages at regular intervals automatically. It makes the communication more efficient when collecting a lot of remote power information. The polling mode offers the precise information of every step required by the monitors. In addition, the PM-213x-CAN also owns the arbitration mechanism which can avoid data collision and error detection.
