Miscellaneous Functions
Function COM_HVPSU2D_GetSWVersion
WORD COM_HVPSU2D_GetSWVersion();
Returns the version of the software interface (the dynamic link library
COM-HVPSU2D.dll
).
This function should be used to check whether a software interface
with the correct version is being used. The function should be called
prior to any other function of the software interface. It does not have
any influence on the communication and can be called at any time.
The return value is an unsigned 16-bit integer (WORD). The higher
byte contains the main version number, the lower byte the subversion,
i.e. the version order within the main version. If the version numbers of
a library
COM-HVPSU2D.dll
are different, check the change list
provided by the manufacturer. There is no guarantee that a library
COM-HVPSU2D.dll
with different version numbers can be used with-
out any changes. In most cases, the user software has to be recom-
piled or modified to match the new definition of the software interface.
