초록
This paper focuses on a method to connect mobile devices such as mobile robot, Automated Guided Vehicle(AGV) to a fieldbus. In this paper, the IEEE 802.11 wireless LAN is used to extend a Profibus-DP network for the mobile devices. In order to integrate these two networks, a protocol converter is developed with two process(i.e., master process of Profibus-DP and virtual master process of IEEE 802.11) and an transmission buffer. Futhermore, a virtual polling algorithm is developed at the protocol conveter in order to satisfy real-time requirements on data communication.
