19.4 Functions and Class Members for Loading
Instantaneous Value Data
This section indicates the correspondence between the functions that are supported
by the instantaneous value loading functions and the class.
There are two types of functions, status transition functions and retrieval functions.
Status transition functions control DARWIN. When using status transition functions,
if measured data is retrieved with a data retrieval function, the measured data
increments by only interval’s worth of data (the status of the extension API
changes).
The retrieval function returns the parameter value. When data is retrieved, the data
value of the current status is returned (the status of the extension API does not
change).

Function Command Class and Member Function
Comm. open - CDAQDA100Reader:: open
Comm. cut - CDAQDA100Reader:: close
Data Retrieval Functions
Function Command Class and Member Function
Meas data Meas channels EF CDAQDA100Reader:: measInstCh
(inst val) Comp channels EF CDAQDA100Reader:: mathInstCh
Channel information data
Meas channels EL CDAQDA100Reader:: measInfoCh
Comp channels EL CDAQDA100Reader:: mathInfoCh
Channel information data is stored internally, but the user can explicitly perform
acquisition.
