Therefore, the block chain operation efficiency is improved by building a management system through two layers of networks, namely a alliance chain layer and an application layer, the high availability, the accuracy and the safety of the configuration data of the programmable controller and the traceability of change are effectively guaranteed, in addition, edge configuration data storage equipment is introduced, the locality and the high efficiency of nearby access of the configuration data are utilized, the information isolation is realized, the management efficiency is improved, and the powerful guarantee is provided for the safety of the management work of the configuration data of the programmable controller.
In some embodiments, as shown in fig. 2, the federation chain node sub-layer may include a first federation chain node and a second federation chain node in communication with each other. The first alliance link point is connected with a configuration data editing network; the second alliance link point is connected with an edge configuration data storage device.
In implementation, the first alliance link node is an alliance link node connected to an application program for editing configuration data in the blockchain network, and an intelligent contract for chaining the configuration data and reading the configuration data is deployed on the first alliance link node. The application program for editing the configuration data in the blockchain network is arranged in the configuration data editing network, and a user can change and update the configuration data in the blockchain network in an editing mode. For example, an industrial engineer may modify the recipe data stored in the blockchain network through an application program in the configuration data editing network, and record information of user operation so as to facilitate tracing of configuration data change.
The second federation chain node is a federation chain node to which each edge configuration data storage device is connected, on which intelligent contracts for chaining configuration data and reading configuration data are also deployed.
The number of the second alliance chain nodes can be kept consistent with the number of the edge configuration data storage devices, and therefore the guarantee is provided for near access. Similarly, the number of the field control networks may also be consistent with the number of the edge configuration data storage devices, and the number of the programmable controllers in the field control networks may also be set according to actual requirements, which is not limited herein. As shown in fig. 2, the number of the second federation chain nodes is two, which are respectively a second federation chain node 1 and a second federation chain node 2, and correspondingly, the second federation chain node 1 is connected to the edge configuration data storage device 1, the second federation chain node 2 is connected to the edge configuration data storage device 2, and the field control network connected to the edge configuration data storage device 2 has three programmable controllers, which are respectively a programmable controller 1, a programmable controller 2 and a programmable controller 3.
When the method is implemented, the edge configuration data storage device is connected with the field control network downwards, and the configuration data of the programmable controller in the network is stored, so that the space locality and the time locality of the configuration data can be provided, a user can acquire the configuration data through the programmable controller nearby in real time, and meanwhile, the space occupancy rate of the edge configuration data storage device is reduced. In practice, each field control network may use real-time industrial ethernet communications.

And the third alliance link node is deployed with a security audit configuration data intelligent contract, a complete change history record of certain configuration data can be established, and the change history record provides a highly credible evidence due to the non-tamper property of the block link.
In particular, the audit requirements may include periodic routine audit requirements and specific change audit requirements. The periodic routine audit requirements are in turn divided into audit requirements for configuration data changes and audit requirements for attached data referenced in the production plan. The audit for the configuration data change is the same as the audit for the attached data quoted in the production plan, and the configuration data is read, and the authorization of a changer is compared with the digital signature of the changer, so that the unauthorized audit of the change is ensured not to occur. The audit of the specific change is an audit of the history of the specific change which is traced after a problem occurs.
In some embodiments, as shown in fig. 2, the application layer may further include a production management application network, and the federation chain node sub-layer may further include a fourth federation chain node; and the production management application network is connected with the fourth alliance link node and used for providing production plan information and writing the production plan information into the alliance link layer so as to realize production management service.
