3.2 Installation via service desktop
Installing additional software
The service desktop makes it possible to install system software or a software update. This
mostly affects installation/update packages that are to be installed via the Windows network.
Installation can be performed in two ways:
● The installation/update package is stored in directory D:\INSTALL. When booting the
PCU the next time, the installation/update process is automatically started while booting.
Only when the installation or update process is completed does normal boot manager
continue and, if necessary, HMI software started.
● The installation/update process can be started from the service desktop directly by
executing the installation/update package.
Using installation directories
Several installation directories can be set to enable an operator setup to be executed
automatically. Installation directories include the subdirectory D:\Install and the directories
listed in the [SetupDirs] section of the E:\Windows\System32\HMIServe.ini parameters file.
The "D:\Install" installation directory is preset there.
The key names contained within a section of the E:\Windows\System32\HMIServe.ini
parameters file must be unique.
The installation directories are evaluated in the sequence described in the parameters file. If
the parameters file is missing or it does not contain a [SetupDirs] section, the preset
"D:\Install" installation directory is considered instead.
If the [SetupDirs] section contains installation directories, but not "D:\Install", the "D:\Install"
directory is not considered within the context of the set installation directories.
When executing a setup using OpFile.txt, the issue of whether or not the setup requires a
reboot once it has been completed is taken into account and displayed via a corresponding
OpFile.txt entry. If a corresponding entry exists, a reboot is triggered. If there is a chain of
setups to be executed one after the other, the reboot is performed once the final setup is
complete.
