7.8.3 Setting items in Component setting
(a) Set a character string length when [String] is selected for [Data type].
(b) When [String] is selected, data are stored as follows:
1) When the value length is shorter than the character string length
NULL codes (00h) are stored after the stored values.
Example: "ABCD" is stored in the device of the tag component, whose
character length is 8.
A B C D
41h 42h 43h 44h 00h 00h 00h 00h
2) When the value length is longer than the character string length
The values whose quantity is equal to the character string length are stored.
Example: "ABCD" is attempted to be stored in the device of the tag
component, whose character length is 2.
"AB" is stored.
(a) Set whether to perform statistical processing or not.
Up to 64 components that have [Perform statistical processing] setting can be set
in all projects. (The number of the set points can be checked on the status bar of
[Device tag settings].)
When the [Perform statistical processing] box is checked, statistical processing is
performed for tag component values.
Statistically processed values can be used by specifying the tag component
values, for which [Perform statistical processing] is selected, in [Job settings].
Note that this setting is not available when:
• [Do not sample] is selected in [Sampling settings].
• [Enhance sampling efficiency] is selected in [Sampling settings].
• The data type of the tag component is [Bit] or [String].
• [Array setting] is set.
(b) When [Perform statistical processing] is selected, set the following items.
