Abstract ： As an excellent Field bus,Can bus has become the major communication platform to construct the modern network for monitor.The interface card will be more crucial ,for we use it to connect the communication equipments. In this paper ,we introduced a designing method
for CAN Bus interface of the front module in a field network based on the CAN bus technology.We also introduced a instance adopting the PHILIPS’s CAN interface products.The method for related programming is enclosed,too.
