SYSLIBCALLBACK.LIB library
The SYSLIBCALLBACK.LIB provides defined callback functions for
activation of run-time events (e.g. logon and logoff of the event
functions).
The description of the library can be found in the “XSoft”
(AWB2700-1437GB) manual and in the Library/Online help of the
“XSoft” programming system.
“SysLibSem” library
The “SysLibSem” library provides functions to generate and use
Semaphore (an enclosed information medium which cant be
interrupted) for the synchronisation of tasks. Semaphore prevents
simultaneous access to critical data which is used by multiple
tasks. If a task accesses a certain area, the mechanism prevents
that other tasks access the same area simultaneously. Only after
the task authorised for access has ended access, is it possible for
another task to access this area.
The description of the functions can be found in the “XSoft”
(AWB2700-1437GB) manual and in the Library/Online help of the
“XSoft” programming system.
“VISU” library
The “VISU” library provides functions with which process
visualisation can be implemented in the XSoft.
The description of the “VISU” library can be found in the
“Function blocks for XSoft“AWB2786-1456GB manual in the
“Visualisation modules: VISU.lib” section.
XC100_File.lib library
The “XC100_File.lib” library provides functions with which the
XSoft can access the file system of the Multimedia Card “MMC”.
The description of the “XC100_File.lib” library can be found in the
“Function blocks for XSoft“AWB2786-1456GB manual in the
“File access block: XC100_File.lib” section.
