19 DATA LOGGING FUNCTION
19.5 Details of Specifications
Data collection conditions
This section describes the timing when data is collected and the conditions under which data is collected.
Each scanning cycle
Collects data during the END processing of each scan.
Precautions
When specifying each scanning cycle, make only one data logging setting.
Time specification
Allows the user to specify the collection time interval.
The CPU module starts collecting data at the time of the following END process after the specified time has elapsed. Ensure
that the "Scan time" is less than "Time specification". If the scan time is longer than the specified time and the collection
interval or the collection timing occurs more than once during the same scan, data is collected only once during the END
processing. Data collection is performed on a scan by scan basis, which is the same operation as when "Each scanning
cycle" is used.
Ex.
When the time interval is set to 10 milliseconds
Data collection conditions Description
Each scanning cycle Collects data during the END processing of each scan.
