Note
If data are written using TRIG, the saving operation is also required to start using the START
key or through the event/action function.
Selection of Writing Data (WRITE DATA)
Select the data to be written from the following:
• All : All measured/computed data are written.
• Alarm : Measured/computed data in all channels are written only when an alarm is
generated.
Setting of File Name (WRITE NAME)
Select the specifying method of a file name from the following:
• Set :
Freely set by the user (up to 5 characters). Characters that can be used for
file names are only those that can be selected from the display; no blanks
allowed. All letters will automatically be capitalized.
• Date : Automatically set based on the date.
Writing Period
• The period in which data are written can be selected from the following:
• INTVL : The same as the measuring period. Measured/computed data are saved
without thinning-out.
• 1, 2, 3, 4, 5 , 6, 10, 12, 15 , 20 , 30 seconds, or, 1, 2, 3, 4, 5, 10, 30, or 60 minutes :
Writing is done with the set period.
However, only those values which are multiples of the measuring period can be
selected.
• LOGIC : Only effective if event/action is set to action DATA_WR. Every time an event
is generated, the data item for 1 scan (1 for each channel) is written.
• When the measuring period is changed, the writing period will not equal the measuring
period or its integral multiples, and is subsequently adjusted to equate with the
measuring period.
Built-in RAM Disk Usage (WRITE MEMORY)
• Select the built-in RAM disk usage from the following:
• LENGTH : Determines file capacity by specifying the number of data items per ch.
• DIV2, DIV4, DIV8, or DIV16 : Use the RAM disk by dividing the disk area into 2, 4, 8
or 16 parts. If the memory capacity is 4 MB, 2 cannot
be used.
• If a file is saved in the built-in RAM disk, the usage of the built-in RAM disk cannot be
changed. For this purpose, initialize the RAM disk or change the setting after deleting
all the files. In that case, necessary files must be saved on a floppy disk.
Writing Data Length (WRITE LENGTH)
• If WRITE MEMORY is set to LENGTH, set the number of data items to be written per
channel, selecting from the following: 10, 20, 30, 40, 50, 100, 200, 300, 400, 500, 1k,
2k, 3k, 4k, 5k, 10k, 20k, 30k, 40k, 50k, or 100k
• However, a data length exceeding a file size of 1 MB cannot be selected depending
on the number of channels.
Note
When using the computation channel, do not write measured/computed data in an application
where the measurement interval is shorter than 0.5 sec, the writing interval is set to INTVL, or
the data length is shorter than 50, if:
• the writing action is in the REPEAT mode.
• writing starts using the event/action mode.
