Settng the Measurement Channels and Computaton Channels to Be Recorded
1. Click Channel. The Channel setup screen appears.
2. Click the Meas. Channel tab to set measurement channels to be recorded; click the
Math Channel tab to set the computation channels to be recorded.
3. Select the Record check boxes of the channels whose measurement/computation
data you wish to record.
Click here.
Click the channel of the measured data you wish to record (the same for Math Channel)

Measurement Groups and Montor Intervals
A data measurement (monitor) interval is assigned to each of the three measurement
groups. The monitor update interval of the data and alarm detection interval follow the
monitor interval. However, if the specified monitor interval is short, the monitor update
interval of the data may be slower depending on the PC environment. If Monitor Interval
is set greater than or equal to 2 min, the Logger acquires data from the MX100 at the
specified monitor interval, but the measurement interval and alarm detection interval on
the MX100 are 1 minute.
Note
The shortest interval that you can specify for the monitor interval is the longest measurement
interval of the shortest measurement intervals of all the input modules assigned to the same
measurement group. For example, if an input module with the shortest measurement interval of
10 ms and an input module with 100 ms are assigned, 100 ms is the shortest interval that can
be specified for the group.
Record Step of Measurement Channels
The record interval is the interval at which the data of measurement channels is saved
to a storage medium such as a hard disk. It is set as an integer multiple of the monitor
interval (up to ×128).
Montor Interval and Record Step of Computaton Channels
The monitor interval of computation channels (computation interval) is the shortest
monitor interval of the measurement group or 100 ms, whichever is greater. The record
step set as an integer multiple of the monitor interval (up to ×128).
Record Start Condton
Select the start condition for saving the data of measurement/computation channels from
the following.
• On Record
Immediately starts recording when the Start Recording button is clicked or Start
Recording is chosen from the Acquisition menu.
• Fixed Time
Starts recording at the specified date/time. Set the date/time as “year/month/day
hours:minutes:seconds” If the specified time has already been passed, the operation
is the same as On Record.
• Interval
Starts recording at the specified time every day or the specified day. Set the time as
“hours:minutes:seconds”
