A-3 Programming Examples for Analog
Input Data Collection with the Library
The High-speed Analog Input Units read each analog input value that has been sampled in the task
periods of the assigned periodic task as more than one I/O data item.
DeviceVariableToArray_100 (Join Device Output Data), a library in the High-speed Analog Inspection
Library of Sysmac Library, enables you to join more than one I/O data item into one array variable.
This section shows programming examples that use this library. The system configuration here as-
sumes that the High-speed Analog Input Unit is connected to a CPU Unit. In the programming exam-
ple where the Unit is connected to an NX-ECC203 EtherCAT Coupler Unit, only differences from the
case where it is connected to the CPU Unit are described. Refer to A-3-3 Connection to the Communi-
cations Coupler Unit on page A - 17 for details.

Programming Example

The following shows a basic programing example for collecting analog input data by using DeviceVar-
iableToArray_100 (Join Device Output Data), a library in the High-speed Analog Inspection Library of
Sysmac Library. Refer to the Sysmac Library User's Manual for High-speed Analog Inspection Library
(Cat. No. W607) for details on the High-speed Analog Inspection Library of Sysmac Library.
