CANopen is one kind of the network protocols based on the CAN bus and mainly used for embedded network of machine control, such as industrial machine control , aircraft engines monitoring, factory automation, medical equipments control, remote data acquisition, environmental monitoring, and packaging machines control, etc.

The PISOCPMX.OCX, CANopen Master OCX for ICP DAS PSIO-CAN series CAN cards, is an Object Linking and Embedding (OLE) custom control for users to establish CANopen communication network rapidly. Using the OCX, most of the CANopen communication protocols will be handled by the member function of the OCX automatically. Therefore, it can help users reduce the complexity of developing a CANopen master interface to easily connect with both ICP DAS and/or any other brand’s CANopen slave devices. The general application architecture is charted as below.
