*1: Use as a reference for processing time. Processing time changes according to the settings and
external factors such as access from GX LogViewer. ( Section 17.1 Processing Time)
*2: The maximum time before/after the trigger where data can be retained and output to a file when the
trigger occurs.
*3: The time required to output 100 lines (records) of data before/after the trigger.
