Abstract

The invention discloses a POWERLINK double-network system based on ZYNQ. A ZYNQ system comprises a first POWERLINK module and a second POWERLINK module, wherein the first POWERLINK module and the second POWERLINK module are respectively connected to a data bus of the ZYNQ system; and the data bus is connected with a shared memory of the ZYNQ system. The first POWERLINK module comprises a first RAM; the second POWERLINK module comprises a second RAM; the first RAM and the second RAM respectively store network data; and when the ZYNQ system carries out double-network data exchange, the first RAM stores the network data to a shared RAM, and the second RAM reads the network data stored by the first RAM from the shared RAM. According to the POWERLINK double-network system disclosed by the invention, simultaneous transmission and receiving of a single piece of equipment on the network data in two groups of networks can be implemented.

Description

technical field [0001] The invention relates to an industrial Ethernet system, more specifically, to a ZYNQ-based POWERLINK dual network system. Background technique [0002] POWERLINK is a real-time industrial Ethernet approved by the Ethernet Powerlink Standardization Group (EPSG). POWERLINK is an open source protocol stack. Different from the traditional Ethernet protocol divided into 7 layers of network layers, POWERLINK defines a communication with three layers: physical layer (standard Ethernet), data link layer (DLL) and application layer (CANopen). Network protocol. The Ethernet has strict real-time and security, and has been put into various industrial Ethernet applications. [0003] ZYNQ is the industry's first scalable processing platform Zynq series launched by Xilinx, designed to provide the required processing and computing performance for high-end embedded applications such as video surveillance, automotive driver assistance, and factory automation.
