(4) Saving the DBs
After the tabular values have been completely entered, the DB can be
saved under "File Save".
The tabular values are then located in the DB for transfer.
4.7.3.3.2 Importing tabular values
The tabular values, provided in the DB, can also be imported from an
external source, e.g. an MS Excel table. However, the following points
should be observed for error-free import:
The source file of the table must have a specific format
The source file must be linked-in as external source file under STEP7
A new DB is generated from the external source file
The necessary points and steps, required for the import operation, will
now be explained.
In order to import an existing table (e.g. generated using Excel) into the
DB, it must be compliant with a specific format syntax:
The table must contain a header, which contains information about
the name of the DB and the version.
Information about the structure and the data type of the tabular values
should then be specified.
The tabular values are then specified (as initial values).
It should be observed that X and Y values must always be specified,
alternating.
The table should be saved with the *.AWL extension.
The table can then be used as external source file.
HINWEIS
The initial value is any value which can be defined for each tabular
value. It is only used if an actual value is not specified for the
associated tabular value.
The tabular values are exclusively defined as initial values. Actual
values are not used.
This significantly reduces the file size and in turn, the required memory.
An example of a table with four X and four Y values, data type REAL is
shown in the following diagram:
