PCI interface card PowerCAN-PCI

CANRS-485industrial

High performance card for PC coup­ling of the CAN bus for con­trol and re­gu­la­tion of the CAN net­work. Compatibility The card is a PCI module with two galvanically isolated CAN interfaces according to ISO 11898, fully compatible with PCI-Specification 2.2 and designed as a PC plug-in card. The CAN controllers used provide 15 message objects each and are based on the FullCAN standard. Microcontroller The Coldfire from Freescale is used as a power­ful micro­con­trol­ler. The controller is oper­ated in 16 bit de­multi­plex­ed mode, which gua­ran­tees an optimal con­nection to the PCI controller. The implemented bootstrap loader makes it easy to load the firmware. Two “on-chip” CAN controllers realize the CAN con­nection in 2.0 B active mode. By default 8 MB RAM and 2 MB Flash are installed. An external program­ming vol­tage does not have to be applied, as the Flash can be written and erased with 5 V. The firm­ware is stored in the flash, which can be updated via the boot­strap mode of the micro­con­trol­ler if required. The board has two galvanically isolated CAN channels and two active 2.0 B CAN controllers, which also allow mixed operation with both 11 bit and 29 bit identifiers. The interface is designed according to ISO 11898 standard. As a high performance card, operation with CAN High (1 Mbit/s) and also CAN Low (125 Kbit/s) is of course possible. Error frame detection This optional feature enables the plug-in card to perform debugging and diagnosis in a CAN network. It has its own logic that detects error frames and counts them in an internal memory. This allows sporadic errors, such as the corruption of messages by a station in the network, to be detected.
