Introduction 1
1 Introduction
The PCI/cPCI/PM-7841 is a Controller Area Network (CAN) inter-
face card used for industrial PC with PCI, Compact-PCI, and
PC104 bus. It supports dual ports CAN’s interface that can run
independently or bridged at the same time. The built-in CAN con-
troller provides bus arbitration and error detection with auto cor-
rection and re-transmission function. The PCI cards are plug and
play therefore it is not necessary to set any jumper for matching
the PC environment.
The CAN (Controller Area Network) is a serial bus system origi-
nally developed by Bosch for use in automobiles, is increasing
being used in industry automation. It multi-master protocol, real-
time capability, error correction and high noise immunity make it
especially suited for intelligent I/O devices control network.
The PCI/cPCI/PM-7841 is programmed by using the ADLINK‘s
software library. The programming of this PCI card is as easy as
AT bus add-on cards.
1.1 PCI/cPCI/PM-7841 Features
The PCI-7841 is a Dual-Port Isolated CAN Interface Card with the
following features:
XTwo independent CAN network operation
XBridge function supports
XCompatible with CAN specification 2.0 parts A and B
XOptically isolated CAN interface up to 2500 Vrms isolation
protection
XDirect memory mapping to the CAN controllers
XPowerful master interface for CANopen, DeviceNet and
SDS application layer protocol
XUp to 1Mbps programmable transfer rate
XSupports standard DeviceNet data rates 125, 250 and 500
Kbps
XPCI bus plug and play
XDOS library and examples included
