Reading And Displaying Data From The Cpu - Siemens SIMATIC S7-1500 Function Manual

The user page uses AWP commands to read out values from the CPU as well as writing
values to it. The user page also uses AWP commands for the definition of enum types, such
as the assignment of tags to enum types for handling the ON/OFF settings.
The user page is structured as follows:
①

In addition, the user page uses an AWP command that writes the special tag to the tag table.
The tag table contains the ID of the user who is currently accessing the page.
