Variable library

The variable library is used to manage all variables used in the current project, including the global variables set by the developer and the local variables saved by the component;

The global variables include the variables set by the commander (see details)Variable management）, this part can be used only when it is networked and the commander has data;

Global variables added by factory can be used in the whole process application; Local variables are the variables saved by the saved and output values of the components used in the current task block. They can only be used in the current task block.

Iglobal variable

Global variables can be viewed and referenced at any time during process application development. You can click & ldquo; Add variable & rdquo; Global variables are added separately. Variable names support Chinese and English. Global variables added in factory are uniformly defined as factory variables, which can be modified and deleted at the same time.

IICommander variable

The commander variable is the demand for data confidentiality in the actual enterprise management. This part of the data that needs to be confidential can be set as a variable in the commander for developers to use, so as to achieve data development isolation. Therefore, the variables set by the commander can be viewed in the global variable only when you log in to the factory online and are allowed to use it.

The variables obtained from the commander are also global variables. The source is defined as the commander. This variable can be viewed and referenced in any process application, but it cannot be modified or deleted. When the commander is set, this part of the variables can be set as a group or a single variable. Please check for details（Variable management）。

IIIlocal variable

Local variable refers to the result content saved and output by the components used in the current process application task block. It is defined as a local variable, which can be viewed and referenced in the task block and cannot be used across task blocks, so as to facilitate developers to transfer data in the task block.
