Writing Special Tags - Siemens SIMATIC S7-1500 Function Manual

Writing special tags

Using special tags
The user page "Remote Wind Turbine Monitor" writes the special tag
"Server:current_user_id" into a tag of the CPU. The tag value contains the value "1" if a user
is logged on and "0" if a user is not logged on. In this example, a user is logged on, so the
tag value is set to "1". The special tag is written into the CPU by the user page and does not
need a user interface.
The code used in the example is:
<!-- AWP_in_variable Name="SERVER:current_user_id" Use="User_ID" -->
