System Tags provide status about the Ignition system, such as memory usage, performance metrics, and so on. System Tags cannot be deleted or modified. In the Tag Browser, under the System folder, there two folders: Client and Gateway. The scope for each is slightly different.
Client-scoped System Tags provide status information about the client's system. Every individual client is going to have their own values like IP address, host name, username, and more. You cannot modify Client System Tags.
There are three folders within the System > Client Tags folder: Network, System, and User. These Tags are provided with Ignition. They can be used with the Vision module for any Vision Client. They cannot be modified.
