• Block
Select the number of blocks when dividing the event data acquisition area into
blocks. Select from [2], [4], [8], and [16]. Select [1] if you do not wish to divide the
area into blocks. When acquiring both display data and event data, the possible
selections are [1], [2], and [4].
• Data length
Set the size (data length) of a single block of the event data acquisition area in terms of the
amount of time data is to be acquired. The selectable data length varies depending on the
sampling interval (sample rate setting) as shown in the table below. It also depends on the
block setting and the number of measurement/computation channels.

• Pre-trigger
Select the range when saving the data existing before the trigger condition is met
as event data. Select the range as a percentage of the data length from [5], [25],
[50], [75], [95], and [100]%. If you do not wish to acquire the data existing before
the trigger condition is met, select [0]%.
• Trigger
Set the trigger condition used to acquire the event data.
• Key
Select [On] if you wish to activate the trigger using key operation.
• External
Select [On] if you are applying the trigger signal through remote input.
• Alarm
Select [On] if you wish to use alarm occurrences as triggers.
Setting Memory and Trend (Setting the Channels for Saving Data)
• Meas/Math/Loop CH
Select the type of target channels from [Meas CH], [Math CH], [Int CH] (PV input of
internal control loops), [Ext CH] (PV input of external control loops),
• First-CH/Last-CH
Set the range of channels to turn [On/Off] depending on the type of target channels.
Meas CH: 01 to 20 ([01] to [10] on models with 10 measurement channels)
Math CH: 31 to 60 (selectable only on models with the computation function option (/M1)
Int CH: 101 to 118 (The maximum channel number varies depending on the
maximum control loop)
Ext CH: 201 to 248
