History Setup Dialog Box
Stamp Time and
Date
Use this option to determine if the time and date are also recorded during
sampling operation.
Auto Stop Use this option to determine if HMI stop recording when the max. number of
record data is reached.
Non-Volatile Using this option can enable HMI to save sampling data in SRAM. The
capacity for saving history data of DOP-AS series is 120Kbytes, DOP-A
series is 240KBytes and DOP-AE series is 360KBytes. (In some HMI
models, the user can save data in USB flash drive or SMC card and the
capacity for saving history data depends on the capacity of USB flash drive
or SMC card.)
Export CSV File The data can be exported to a CSV file for the user to read and edit more
easily in the Windows@ Excel or other text editing tool. It allows the user to
read max. 65536 rows and 256 columns of data in the Windows@ Excel
environment. If the sample number of the sampling data exceeds 65536,
when the user uses Windows@ Excel to open the CSV file, an error
message will display. At this time, the user can use Notepad or other text
editing tool to open the CSV file.
If Auto Stop option is selected also, HMI will stop recording the data after the
numbers of records have reached the setting value of Sample Number
option. If Auto Stop option is not selected, when record number of data
exceeds the setting value of Sample Number option, it will delete the
records from the first record and insert the new record again. But, the data
of the exported CSV file will not be sorted and listed by the record time.
Trigger There are Timer and PLC two options. It means that the sampling action is
controlled by the Timer of the HMI or the external controller, i.e. PLC. When
PLC option is selected, it indicates that the trigger bit designated by the
register for sampling history buffer in the control block control the sampling
action. Regarding the settings of the control block, please refer to Chapter 5.
