Design And Implementation Of Embedded Fieldbus Gateway Based On ARM

Fieldbus connect industrial devices and build-up devices network easily,but some enterprises set different fieldbus protocols which are incompatible with other enterprises for their own interest,thus devices in different fieldbus networks communicate with each other difficultly. On the other hand, it is difficult to connect fieldbus to office network which mostly built in ethernet protocol. Industrial Ethernet will be the main orientation of control system network and can easily realize amalgamation of devices network with office network. But traditional fieldbus has been widly used in factory field and will act an important part for a long time, so it is necessary that to realize fieldbus connect to office network ,make it has the capability of inter-connection and inter-operation ,and keep it's architecture unchanged.The paper discusses a method to slove the problem.That is making use of EtherNet/IP protocol which is one of industrial Ethernet protocols, to design an embedded fieldbus gateway. The gateway mainly consists of S3C2410, a 32bit high performance microprocessor based on ARM core, to realize interconnection DeviceNet network, ControlNet to Ethernet.
