21.3 Correspondence between Functions for

Instantaneous Value Data Loading and Member
Functions - DARWIN/Visual Basic -

This section indicates the correspondence between the functionalities that the

extension API supports and the Visual Basic functions.

Note

This extension API provides a portion of the functions common to the DARWIN series
instruments. Model-specific functions, setup functions of the setup mode, and A/D
calibration functions are not given. The functions can be added by using the
commands of the DARWIN communication function.

The word ìcommand” in the table signifies the command of the DARWIN
communication function. For the details on the commands, see the Communication

Interface User’s Manual.

There are two types of functions, status transition functions and retrieval functions.
Status transition functions control DARWIN.

With retrieval functions, the parameter values of the current status are retrieved.
When using retrieval functions, the data value of the stored current status is

returned (the status of the extension API does not change).
