6.4
6.4.1 Search function principle
Overview
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 on NCU if HMI
Advanced and HMI Embedded sl are both operated in parallel on a single hardware platform.
In this case, "Expand user interface" accesses the same configuration files in
ShopMill/ShopTurn on NCU running on HMI Embedded sl as on HMI Advanced.
Supplementary Conditions
HMI Embedded WIN32 evaluates the "mmchome"property in section [DHSTART] in the
DH.NI configuration file containing the root directory for the data management path. DH.INI
must be stored in the BIN directory path on which MMC0 .EXE is started. The maximum
length for the data management root directory path entry is 100 characters.
Startup
On startup, HMI Embedded WIN32 uses the entries in the registry to ascertain where HMI
Advanced is installed. Within the directory indicated in the registry, a search is made for the
DH.INI file in the ..\user, ..\oem, ..\add_on, ..\mmc2 subdirectories 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 the 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
Control variables for search sequences
Search sequence with HMI Advanced:
● CUS directory in the data management path specified in dh.ini
● CMA directory in the data management path specified in dh.ini
● CST directory in the data management path specified in dh.ini
● COM directory in the data management path specified in dh.ini
