Description
Technical Field
The invention relates to the technical field of Ethernet Powerlink communication protocols, in particular to a preprocessing method and a preprocessing system for automatically issuing and monitoring Powerlink main station configuration.
Background
Ethernet Powerlink is a real-time communication protocol over standard Ethernet, an open communication protocol managed by the Ethernet Powerlink Standardization Group (EPSG), and was used by betaley, austria automation corporation in 2001. The problems of delay and jitter of a CSMA/CD mechanism of the standard Ethernet are solved by modifying a data link layer of the standard Ethernet, and a CANopen protocol is used in an application layer, so that the CSMA/CD mechanism has good interoperability.
The current research on Ethernet Powerlink focuses on several aspects:
(1) the protocol is applied as follows: such as robots, vehicles, industrial internet, etc.;
(2) synchronization performance: such as reducing master station synchronization signal (SOC frame) jitter, slave station network transmission delay compensation, slave station synchronization interrupt response delay compensation, etc.
The research results promote the improvement of performance indexes of the Ethernet Powerlink master station and slave station in the aspects of transmission period, delay jitter and the like.
However, in the application scenario of multiple actual master-slave systems or multiple sets of master-slave systems, some defects and pain points are not solved. For example: in some customer sites, due to changes in the networking topology of the customer site, adjustment of the number of devices, and changes in the data transmission requirements of the devices, reconfiguration of the system may be required, including but not limited to adjusting the cycle period of Ethernet Powerlink, adding CN nodes, changing the data configuration mode of CN nodes, and the like. After the Ethernet Powerlink protocol stack is recompiled or the MN's mac is regenerated using a tool (e.g., open CONFIGURATOR), the newly generated protocol stack or configuration file needs to be manually imported into each MN's master node and the application needs to be restarted to enable the new configuration to take effect. The process needs to log in MN master station nodes (each master station with multiple master and slave redundancy or each master station with multiple master and slave systems) one by one for operation, and due to the complexity of an industrial field, operation omission, operation errors and the like are easy to occur in the updating process, so that great inconvenience is brought to the maintenance and the customer use of Ethernet Powerlink master station equipment manufacturers.
