1-3-10 Data Blocks
Data blocks (recipes) enable reading/writing numeric values and character strings from/to memory ar-
eas, such as those in a PLC. Data blocks can be used to easily change the arrangement of the system.
Create the data in CSV files and store them in the PT beforehand. The created data can be used to
make changes while operating the PT.
Examples: Setting the width (numeric value), height (numeric values), and color (character string) in
the PLC (Refer to the figure shown below.)
Set width: 150, height: 54, and color: blue for product B.
Just by selecting product B, these three items can be set for the PLC. If product A is selected, a width
of 100, height setting of 52, and a color setting of red will be set for the PLC.

Using data block, the user does not need to save the data in the PLC beforehand, so that memory of
the PLC can be saved and ladder program can be reduced. Data blocks also have the following fea-
tures.
Data in CSV format can be edited and managed on a personal computer. •

Data can be edited on the PT.
Data can be written to a Memory Card.
Data can be read from a Memory Card.
Processes values and character strings can be handled.
Maximum number of rows: 1,000. Maximum number of columns: 500. Data blocks with both 1,000
rows and 500 columns, however, cannot be set.
Refer to 2-16 Data Blocks - Restrictions for Data Blocks in the Programming Manual for details.
