Conditions for Collecting Data
In the Logging Group properties, set the condition for collecting data.
| [Value Change] | Use these options to collect data whenever there is a change
in the variable value.
[Execution Condition]
|
||||||
| [Periodic] | Use this option to collect data at regular time intervals.
Set the frequency and unit in the [Frequency] and [Units] fields.
You can stop collecting data by turning ON the variable set as the [Interlock]. |
||||||
| [Script] | Use this option to collect data based on the condition set
in a script. In the script editor, set the script to start and
stop collecting data.
Data Logging |
- The display unit reads values stored
in device addresses of associated external variables at the interval set
in the scan rate. For example, if the
data logging collection cycle is shorter than the scan rate, the same
values keep getting collected until the next scan by external variables
for device address values.
For information about scan rate, refer to the following.
Setting the Interval for Reading External Variable Values (Scan Rate) - Even if the [Condition Type] is set to [Value Change] or [Periodic], if
there is a script that collects data in a [Data Logging] operation, data
will be collected when the script is triggered. Note that when data is
collected by the script, data is also collected at the [Periodic] or [Value
Change] timing.
Data Logging
Example: Script is triggered while data is collected every 5 seconds
: Data collected every 5 seconds
: Data collected by the [Data Logging] operation
Maximum Number of Records for Logging Data
As the number of records increase, collecting data at the set timing may not be possible and drawing trend graphs may take more time.
When setting the [Max Record], refer to Guideline for Maximum Number of Records, and verify operations at run time.
- Plotting many channels and data in trend graphs will reduce
performance of the display, even if the number of records is below
the guideline.
About Display Performance of Trend Graphs
- When there are a large number of records, erase logging data
to improve run-time performance.
