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().
