MX100 for Extended API

12.2 Correspondence between the Functions and

Class/Member Functions - MX100 -

This section indicates the correspondence between the functions that the Extended
API supports and the class member functions.

There are two types, status transition functions and retrieval functions.
Status transition functions control the MX100. When measured data is retrieved

with the data retrieval function, the measured data advances by only one
measurement interval’s worth of data (the status of the Extended API changes).

The retrieval function returns the parameter value. When data values are retrieved,
the data value of the current status held by the Extended API is returned (the status

of the Extended API does not change).

Status Transition Functions

The FIFO column in the table indicates the FIFO operation when the function is
executed while FIFO is running.

Stop: Stops the FIFO when the function is executed.
Continue: Continues the FIFO even when the function is executed.
