Scaling
Set sampled device values to execute linear function transformation.
Operating procedure
1.
Click the [...] button for "Scaling" in the [Data] tab on the "Data logging setting" screen.
2.
Set "Operand 1", "Value 1", "Operand 2", and "Value 2" on the "Scaling" screen and click the [OK] button.
• When the data which is specified for scaling is used in other settings, the value after performing the scaling
conversion is applied to the data.
• For operation processing specified in the scaling, all values are calculated as double precision floating point
numbers.
The result is output with the specified output format.
• When the calculation result is over the maximum value or under the minimum value for the specified output
format range, the data to be output differs.

Precautions
• When outputting data to a folder name or a file name
If Word [Signed], Double Word [Signed] is specified to the data type, the negative values may get output to the file name or
the folder name depending on the device value of the CPU module.
If a negative value is output, "-" will be added to the number of digits of zero padding even when the number of total digits is
specified in "zero-padding."
When fixing the file or folder name length, specify Word [Unsigned]/Bit String [16-bit], Double Word [Unsigned]/Bit String [32-
bit] and not Word [Signed] or Double Word [Signed] for the data type, and specify the number of digits of zero padding.
Count condition
Specify the condition to count output values.
Operating procedure
1.
Click the [...] button for "Count condition" in the [Data] tab on the "Data logging setting" screen.
2.
Specify the "Count condition" and "Count value" on the "Count condition" screen and click the [OK] button.
String type data/string constants are compared by the following character code.
Unicode text files, binary files: UTF-16 (little endian)
CSV files: ASCII
