The CANopen is a kind of network protocols evolving from CAN (Controller Area Network) bus, used on vehicle control system in early days, and has been greatly used in various applications, such as vehicles, industrial machine, building automation, medical devices, maritime application, restaurant appliance, laboratory equipment and research.

The PM-3133-CPS power meter provides the CANopen interface for users to easily gather the real-time power consumption information in their CANopen applications. It will be more efficient by using CAN bus than serial communication when there are plenty of meters to be monitored. User can use CANopen PDO event time feature to response messages at regular intervals automatically. It makes the communication more efficient when collecting a lot of remote power information. In addition, the PM-3133-CPS also owns the arbitration mechanism which can avoid data collision and error detection.

The PM-3133-CPS also 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 that makes it especially suitable for networking “intelligent” devices as well as sensors and actuators within a system or sub-system.
