Factory automation system and data synchronization method for same

Abstract

The invention provides a data synchronization method for a factory automation system, which includes: building a data communication channel between a factory automation service system and a factory automation configuration system; making a data synchronization request for the factory automation service system through the data communication channel by the aid of the factory automation configuration system; and synchronizing data according to the data synchronization request by the aid of the factory automation service system. In the data synchronization method for the factory automation system, as the factory automation configuration system is used for making the data synchronization request for the factory automation service system through the data communication channel for any data configuration update, the data of the factory automation service system can be kept synchronous with data of a database. The invention further provides the factory automation system.

Description

technical field [0001] The invention relates to the technical field of automation system control, in particular to a data synchronization method of a factory automation system and the factory automation system. Background technique [0002] In the current field of semiconductor production, factory automation is particularly important. At present, factory automation mainly connects the factory mainframe and process equipment through some intermediate software, such as factory interface. The command is communicated to the process equipment side to carry out related process processing and related configuration, thus providing the operator with a simple and easy-to-understand operation platform to complete the automatic operation. [0003] The existing factory automation service (Factory Automation Server, hereinafter referred to as FA Server) system is a specific realization of the factory interface. It can run independently with the factory host for message interaction, and ...

This increases the complexity of operation and the uncertainty of human operation

When the FA Server system cannot be shut down and restarted immediately due to machine operation and other reasons, the user cannot log in to the FA Config system, which will cause unnecessary time waiting

Furthermore, if the FA Server system is shut down abnormally, the key value of the running key in the registry will always remain true, or if the key value of the running key is manually modified after the FA Server system is closed, it will cause The FA Config system is always inaccessible or misjudges whether it is operational

In addition, because after the user logs in to the FAConfig system, the FA Server system can also be started, but data interaction cannot be performed between the two, which will cause any configuration changes made by the operator to the FA Config system to be saved after the FA Server system is started. After that, the data of the FA Server system cannot be kept in sync with the updated database in time, resulting in an error that the user's expected data is inconsistent with the processed data of the FA Server system
