OVERVIEW

1.2 Processing Overview

The high speed data logger module logs (records/saves) device data sampled from a
programmable controller CPU as files on a CompactFlash card.
Files which can be created are data logging files, event logging files, and report files.
In the data logging file, all the sampled data in the specified period can be saved. In this
way, sampled data can be analyzed in depth. ( Chapter 7)
In the event logging file, only the specified data correspond to the event condition can be
saved. In this way, only necessary data can be identified. ( Chapter 8)
In the report file, data can be saved as an Excel file. In this way, by only configuring the
settings in advance, a report with desired graphs and layouts can be created
automatically. ( Chapter 9)
The overview up to creating a file is shown in the figure below.
