7.2 HMI Embedded and HT6
Central control file COMMON.COM
This file contains information relating to:
• Assignment between start softkeys and configuration files
• Assignment of user keys to configuration files (only relevant for HT6)
• Assignment of display numbers to configuration files in PLC interface DB19
• Control entries (size of LOG file, available memory on RAMDRIVE for
configuration files, search criteria for language-dependent texts, search criterion
for configuration files).
Details of how to make the appropriate entries in file COMMON.COM for the HMI
Embedded and HT6 can be found in the next section.
Changes to COMMON.COM only take effect following a restart.
Storage location
The central control file COMMON.COM must be stored in one of the following NC
directories:
• \CMA ;Manufacturer cycles directory
• \COM ;Comment directory
• \CST ;Standard cycles directory
• \CUS ;User cycles directory
The system searches through the directories for COMMON.COM in the following
order. The first file with this name is evaluated.
The files with the configured form definitions must be stored:
• in one of the three directories specified above
• In the Flash memory of HMI Embedded and HT6
(the DOS file name conventions apply here) BIN directory
File names
All file names must follow DOS conventions (xxxxxxxx.eee).
Size of display files
The total size of the file with compressed images CST.ARJ is 150 kB.
In the case of HMI Embedded, 100 kB of this is used by the system.
