Problems solved by technology
[0007] The existing PowerLink and Profibus-DP conversion device adopts the combination of PowerLink slave station and Profibus-DP master station. Although the Profibus-DP device can be connected to the PowerLink network, the Profibus master station protocol part uses a special Realized by Profibus-DP master protocol chip or special Profibus-DP communication module, no solution using pure software Profibus-DP protocol stack has been seen yet
Using specialized chips or modules, although the development cycle is short, the cost is high and the hardware is relatively complex

The invention discloses a device for switching from PowerLink industrial Ethernet to Profibus-DP. A hardware part mainly comprises a main control chip with a high-speed UART (Universal Asynchronous Receiver / Transmitter) port, an Ethernet physical layer transceiver and a Profibus-DP physical layer transceiver. On the basis of an ARM (Advanced RISC Machine) and a pure software Profibus-DP protocol stack, Profibus-DP equipment is accessed into a PowerLink network by combining a PowerLink slave station with a Profibus-DP main station. According to the device, a Profibus-DP main station protocol is realized by adopting the software protocol stack and the physical layer transceiver, so that the hardware structure is simple, and low cost is realized; and an embedded real-time operating system is taken as an operating system platform, so that the efficiency of protocol conversion is increased greatly, and the requirement of high instantaneity of the Profibus-DP and the industrial Ethernet can be well met.
Description
technical field [0001] The invention belongs to the technical field of industrial automation, and relates to a conversion device from PowerLink industrial Ethernet to Profibus-DP field bus, in particular to a PowerLink industrial Ethernet to Profibus-DP field based on ARM platform and pure software Profibus-DP protocol stack Bus conversion device. Background technique [0002] The industrial measurement and control system is mainly used to complete functions such as data collection, processing, and real-time monitoring of remote on-site points. The application of fieldbus technology, industrial Ethernet technology, etc. can realize the networking of the measurement and control system and improve the performance and openness of the system. Therefore, in the specific application of industrial control systems, there is often a need for protocol conversion from fieldbus to industrial Ethernet. . [0003] Among the various existing fieldbus standards, PROFIBUS fieldbus is a rel...
