Montor Interval
Sets the measurement interval, monitor update interval, and alarm detection interval.
However, if the specified monitor interval is short, the data monitor update interval may
be slower depending on the PC environment.
If the monitor interval is set greater than or equal to two minutes, the Integration Monitor
acquires data from the MX100 at the specified interval, but the measurement interval and
alarm detection interval on the MX100 are one minute.
The input modules can be divided into three interval groups, and different monitor
intervals can be specified for each interval group.
Note
The shortest interval that you can specify for the monitor interval is the longest 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.
When saving backup data to the CF card, for monitor intervals of up to one minute, the data
is saved at the monitor interval, and for monitor intervals of two minutes or more, the data is
saved at one-minute intervals.
Record Interval of Measurement Channels
The record interval is the interval at which the data of measurement channels is saved to
a PC hard disk. It is set as an integer multiple of the monitor interval (up to ×128).
Montor Interval and Record Interval of Computaton Channels
The monitor interval of computation channels is the minimum monitor interval of the
interval group or 100 ms, whichever is greater. The record interval is set as an integer
multiple of the monitor interval (up to ×128).
Note
Computation channels are not saved to the CF card.
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 Record button on the Monitor screen is clicked
or Record is chosen from the Acquisition menu.
• Fxed Tme
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.
• Math
Starts recording when the StartRec() event function (see “Event Function” under
“Explanation” in section 2.5) is executed on a computation channel. This is valid when
you click the Record button on the Monitor screen (see section 2.7) and the word
“Waiting” is displayed.
