A link between an autonomous devicenet scanner and software via MODBUS/TCP.
Abstract
Industrial automation networks recently have boomed, including DeviceNet as one of the most popular protocols. In a DeviceNet network, slave devices usually sensors and actuators are identified, and at least a scanner in charge of configuring and managing network transactions. Such machine must communicate directly to other devices on DeviceNet network and deliver the collected information to send it to a higher hierarchical level equipment, such as a plc or a pc. Although there are specifications and recommendations to build a DeviceNet slave, there is not a clear pattern to implement the DeviceNet master or scanner nor a design of the communication link between the scanner and control equipment. In this paper we show a communication scheme specifically designed to support data exchange between a DeviceNet scanner and a software resident on a pc.
