5 = 2.Rule chain creation =
6
7 The system provides a default root rule chain that supports user use. No changes are made on the root rule chain, but the root rule chain is exported and re imported, and then modified and configured in the newly imported rule chain.
8
9 Firstly, follow the steps below to export the root rule chain. After clicking on export, the system will automatically download it, and the exported file will be in JSON format.

52 Next, we will explain the configuration of rule nodes that may be commonly used in different classes to manipulate data. As the default device configuration was applied in the creation of the previous device ,
53
54 the rule chain used in the default device configuration is the Root Rule Chain. Therefore, the following demonstrations are all configurations made in the Root Rule Chain.
