HSL Function Library 77
5 HSL Function Library
This chapter describes the functions for developing programs in C,
C++, or Visual Basic.
5.1 List of Functions
This section presents all the functions. The function prototypes
and common data types are declared in HSL.h. It is recommended
that you use these data types in your application programs. The
following table shows the data type names and their ranges.
All HSL function calls were revised. Refer to the mapping table in
Appendix B. All function calls have the same prefix HSL_. The
function belonging to a system level purpose has the following
form:
HSL_{action_name}. e.g. HSL_initial().
If they belong to a discrete I/O module purpose, the function is as
follows:
HSL_D_{action_name}. e.g. HSL_D_read_input()
If they belong to an analog I/O module purpose, the function is as
follows.
HSL_A_{action_name}. e.g. HSL_A_write_output().
If they belong to a motion control module purpose, the function is
as follows.
HSL_M_{action_name}. e.g. HSL_M_start_tr_move().
