The PEX-CPM100 gives a very powerful and economic solution of an active CANopen master device with one CAN channel. It uses the NXP SJA1000T and 82C250 to be the CAN controller and transceiver, which provide bus arbitration, error detection with auto correction and re-transmission function. The 16-bit on-board microcontroller with real-time O.S., MiniOS7, allows many features, such as real-time message transmission and reception, filtering, preprocessing, and storage of CAN messages. Under the effect of the powerful microcontroller, this card can be made for one CAN controller manager without losing data, even in systems with a high PCI bus load. Therefore, the CANopen critical process can be implemented directly by CANopen firmware in the PEX-CPM100. In addition, users can develop their CANopen application by using the CANopen library on the host computer. When the PEX-CPM100 is active, the data exchange between users’ application and CANopen firmware is performed via the memory mapping method of the PEX-CPM100.

The CANopen master device also supports CANopen Motion Library, which follows the CiA-402 specification and supports the functions of position control, velocity control, torque control, synchronized control, etc. For more information, please refer to CANopen Motion Library webpage.
