Naming concept

Rules for computer names
The selection of the computer name is crucial to the project configuration.
Select short and descriptive computer names that provide some information about the function
of the PC station in the overall plant. Note the following rules:
● The computer name may only contain uppercase letters and numbers.
● The computer name must start with a letter.
● The computer name may only contain up to 15 characters (limited by the operating system).
Note
The following names must be identical when you configure an OS or BATCH Server and
an Engineering Station:
● Computer name
● Name of the PC station
Note
You can find additional information about the naming conventions in the following
documentation:
● PCS 7 Readme V8.2 (https://support.industry.siemens.com/cs/ww/en/view/109478781)
● "SIMATIC Process Control System PCS 7 Engineering System
support.industry.siemens.com/cs/ww/en/view/109485969)" manual
● WinCC online help (search string "illegal characters")
Changing computer names
The computer name can no longer be changed after the installation of PCS 7. If you do change
the computer name, you will have to install the computer again (Restore DVD). Changing
computer names often leads to problems in practice (e.g. in the case of multi-station systems
with the SQL server installed).
The following rules must be adhered to:
● If you want to change the computer name for a bundle PC outside of the restore process,
perform a new installation with the Restore DVD.
● If you want to change the computer name for a PC you have installed yourself, perform a
new installation of Windows.
