Library

Description

SysLibCallback.lib

This library provides the functions SysCallbackRegister and
SysCallbackUnregister, which serve to activate defined callback functions
for runtime events.

SysLibCom.lib

This library supports the serial communication with a target system.

SysLibDir.lib

If supported by the runtime system, you can use the functions of this
library to handle a file directory system on the target system. Entries of
the directory can be read and modified. The execution is synchronous.

SysLibDirect.lib

The functions of this library serve to access variables by indices with

which they are referenced in the runtime system. For detailed
information see the description of the particular runtime system.

SysLibEvent.lib

This library serves to synchronize and control the processing of two (IEC-)
tasks.

SysLibDPV1Hilscher.lib

This library supports the acyclic Profibus DPV1, Class 1, Read- and Write-
Services for the data transfer between Master and Slaves. The data are

addressed within the slaves by slot and index.

SysLibFile.lib

This library supports a file system on the target computer. If the target
supports the functionality, the library functions can be used to open,

close, delete, rename, write to or read from files. Further functions are

available for getting the file size or the date of the last access, as well as
for reading or modifying the offset. The execution is synchronous.
