7.4 Common HW plattform for both HMI systems

HMI Embedded WIN32 searches the configuration files for Expand user interface
on the same paths as HMI Advanced. The starting point is the data management
path.
The search sequences described below are relevant for ShopMill/ShopTurn if HMI
Advanced and HMI Embedded are both operated in parallel on a single hardware
platform. In this case, Expand user interface accesses the same configuration files
under ShopMill/ShopTurn running on HMI Embedded as on HMI Advanced.
Supplementary conditions
HMI Embedded WIN32 evaluates the mmchome property of section [DHSTART]
in configuration file DH.INI, which contains the root directory for the data
management path.
DH.INI must be stored in the BIN directory on which MMC0.EXE is started. The
maximum length for the data management root directory entry is 100 characters.

General information about searches

Power-up
On start-up, HMI Embedded WIN32 uses the entries in the Windows Registry to
ascertain where HMI Advanced is installed.
Within the directory indicated in the registry, a search is made for file DH.INI in the
subdirectories ..\user, ..\oem, ..\add_on, ..\mmc2 in the sequence specified. If
DH.INI cannot be found there, a search is carried out for the file in the currently
selected directory of HMI Embedded WIN32.
Example:
If HMI Advanced was found on f:\HMI\HMI Advanced, then a search for dh.ini is
made in the following sequence:
f:\HMI\HMI Advanced\user
f:\HMI\HMI Advanced\oem
f:\HMI\HMI Advanced\add_on
f:\HMI\HMI Advanced\mmc2
