Description

CPC-PCI low profile is a passive CAN-plug-in board for PCI slots. CPC-PCI low profile was designed for industrial series application and has a robust and cost efficient construction. CPC-PCI low profile supports either one, two or four CAN-channels that can be operated independently with different data rates. The interface comes with the NXP CAN-controller SJA1000, that offers good diagnostic attributes.CPC-PCI low profile maps the CAN-controller(s) directly in the address space of the PC and allows access of the CAN-messages with low latencies. Existing software for the supported CAN-controller can easily be adapted. For the operating systems Windows and Linux software development kits with identical API are free of charge.Optionally, CPC-PCI low profile is available with galvanic separation between PC and CAN-bus. A galvanic separation between the CAN-channels is also possible by separate DC/DC converters.

Programming Interface

Configuration and CAN-communication with CPC-PCI low profile are done by accesses to the memory address area of the PC. The appropriate data areas are mapped by CPC-PCI low profile and “plug & play” software into the memory address space. Due to the direct access to the CAN-controllers the CAN-communication takes place with low latency time. The memory used by CPC-PCI low profile is divided in several sections. The control registers allow the detection of the interface type similar to the interfaces CPC-Card, CPC-XT and CPC-104 and the generation of hardware resets for the CAN-controllers. The access to the CAN-controllers occurs via a separate memory space for each interface. In these memory spaces, the sending and receiving buffers as well as the control registers of the CAN-controllers are accessible. A specification describing the access to the CAN-controllers as well as drivers for Windows and Linux are available separately.
