Additional Information
In this example, fluctuations are significantly suppressed using only the Ch1 Moving Average
Filter 1. If you cannot suppress frequency fluctuations from a noise component only with the
Ch1 Moving Average Filter 1, use the Ch1 Moving Average Filter 2 together to suppress the
fluctuations. At this time, design the Ch1 Moving Average Filter 2 with the same design proce-
dure and same requirements as the Ch1 Moving Average Filter 1 after you design the Ch1
Moving Average Filter 1.
A-4-3 Programming Example
This section shows programming examples that use the following libraries in the High-speed Analog
Inspection Library of Sysmac Library.
• DeviceVariableToArray_100 (Join Device Output Data)
• DataRecorder (Data Recorder)
• LogDataToCSV (Write Log Data to CSV File)
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.
In the following programming examples, you collect analog input values of Ch1 and then export the
collected data to a CSV file.
Unit Operation Settings
The following table shows the Unit operation settings for the High-speed Analog Input Unit that you set
in the program. Use the default values for settings that are not given in the table.
