History Setup Dialog Box
Read Address It is used to set the starting address for sampling the history data.
Data Length
(Word)
It is used to set how much words the user wants to sample. The range is
within 1 ~ 13 continuous words. It indicates that max. 13 continuous words
can be sampled.
For example: If the setting value of Data Length is set to 6, it indicates that
there are 6 continuous Words can be sampled.
Cycle (ms) It is used to set the sampling cycle time for reading address (how long it is to
read address one time). If the Trigger option is PLC, this option will be
ineffective and the sampling operation should be triggered by the control
block flag. For the settings of the control block, please refer to Chapter 5.
Sample Number This option is used with the Auto Stop option. If the Auto Stop option is
selected, HMI will stop recording the data after the numbers of records have
reached the setting value of Sample Number option. If the 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. The record data will be name as “History.dat”
and the user need to use the software, Data Access which is attached in
HMI editing software, to open this file. Data Access will sort and list the
history data by record time automatically.
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.
