| Windows CE embedded operating system is a kind of operating system whose size can be customized by users' requirement ,that is developed in MICROSOFT in order to apply to industrial field condition,and increase the field fixings'control exactness.Such as PDA ,this kind of control field may be manufactured as small as a man's palm.The computers which are embedded into some sets are called Embedded computer.So,it's most visiable feature is the so small and compact volume.The embedded computer provides kinds of function interfaces for users,administrates the whole system's inputs and outputs,and contral set's calculate ability.So that,sets with Embedded computer have more excellence.Profibus-DP FieldBus is a kind of communications standard and technique developed for the industrial field condition.To link the field fixings that require controlling and watching to the field controller whose core is embedded oprating system ,and realize field controlling is its function.For field fixings that may communicate each other,they can communicate each other independently by means of Profibus-DP,then the work's security and efficiency are increased.Speaking vividly, Profibus-DP FieldBus system is a small DCS control system.In the whole , Profibus-DP FieldBus puts parts of the DCS control system's function ,that will be realized by the field controller,down to the industrial field.By means of combining the advantages of the PC104 bus embedded computer system and the Profibus-DP fieldbus,manufacture a Profibus-DP fieldbus communication main board based on PC104 bus embedded computer system.Seeing from the combining, there has a very little information about it so far,so we must study in our selves.Thit means we can do something in the field of industry watch. In addition, manufacture a modem based on PC104 bus embedded computer system's RS232 serial port. The PC104 bus embedded computer system may communicate with manager computer through modem and public phone net...
