6. Change the project name "Comp_Prj" of plant A to "01_Plant_A".
Note
Project names for multiprojects and projects can be assigned freely. PCS 7 automatically
creates the path where the data is to be stored in the Windows file system. The path name
may differ from the project name (shortened to eight characters). As PCS 7 data is only
edited in the SIMATIC Manager, this path name is of no consequence to the user.
7. Change the name of "SIMATIC H station (1)" to "AS1_H".
8. Change the name of the S7 program of the station "AS1_H" (e.g. to "S7-ProgAS1").
Note
Assigning unique names to the S7 program files of different automation stations is
recommended. S7 program names may not contain any blanks.
