19.1 Application Example
Two types of data logging functions are available: Continuous logging and trigger logging. Application examples are shown
below.
Continuous logging
Data can be collected at specified intervals and recorded. This enables facility and product data to be managed with time
stamps for use to achieve traceability.
In addition, collected data logging files can be saved in CSV file format. A CSV file can be opened as a table and expected to
be used for reports created by customers.
Trigger logging
Data can be collected at a specified timing and a specified amount of data (a quantity of records) before and after the trigger
condition is satisfied can be recorded.
For example, by specifying the device for facility error occurrence, only facility data before and after error occurrence can be
saved as a data logging file. This enables data analysis when an error occurs to be performed efficiently.
