PISO-CPM100U-T

The PISO-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 PISO-CPM100. In addition, users can develop their CANopen application by using the CANopen library on the host computer. When the PISO-CPM100 is active, the data exchange between users’ application and CANopen firmware is performed via the memory mapping method of the PISO-CPM100.

CANopen Motion Library (CiA DSP-402)

The PISO-CPM100U provides the motion control library now. This library follows the CANopen standard DSP-402. It is available on the Windows 2000/XP/Vista or Win 7(32-bit version) operation system. The DSP-402 is one kind of the standard CANopen application profiles, and specially designed for motion control systems. In addition to making the management of the CANopen motors easy, this communication protocol can reduce the wire connection between the controller and motors, and provide rapid troubleshooting functions. With the PISO-CPM100U and CANopen Motion Library, you can do various motion control functions, such as position control, velocity control, toque control, and synchronous action without having the background knowledge of the complex and abstruse CANopen protocol. The CANopen Motion Library is able to link many CANopen motors so that the multi-axis motion control by one host becomes reachable. While controlling motors, you can also use the APIs of the PISO-CPM100U library to access CANopen remote I/O modules which follows the DSP-401 at the same time. Therefore, building a motion control application becomes more easy and convenient.
