Functionality
The following functions are not available:
Search functions: - SB (search forwards)
- SF (search backwards)
Displays activated from the PLC
With HT6, it is not possible to select/deselect displays via a separate operating
area.
Size and number of configuration files
The entire memory space for all configuration files including texts amounts to
256 KB, of which approx. 128 KB are occupied by the system; therefore, 128 KB
remain for the user. The total permissible number of configuration files is 10.
PCU20 256 kB are available to the user. With HMI Embedded, the
maximum number of configuration files is 10.
PCU20 and PCU50 The maximum size of a configuration file is 30 kB.
Display images
A graphics program, which can be used to create images for configured screen
forms in PCX format, must be procured separately by the user, if required.
Color format: 16 colors.
With PCU20 and PCU50, images in BMP format can also be used as well as
converted bitmaps with up to 256 colors (PCX2BIN tool).
Files containing displays in PCX format must be stored in converted, compressed
form in the Flash memory. The PCX_CONV tool is available in the application
environment for this purpose. Image files in PCX format must not exceed 64 KB
per picture.
Performance
If screen form configuration files are executed from the Flash memory, screen
forms are displayed and processed significantly faster. This option should therefore
be chosen where possible.
