Importing recipe records
Requirements
Import functions are configured.
Procedure
1. Customize the import settings on the user interface of the HMI device. For example, you
can set the CSV file path.
2. Use the button or the key on the HMI device which is assigned the "Import recipe
records" function.
Result
The recipe data records are imported. If the structure of the CSV file is different from the
recipe structure, deviations are treated as follows:
•
Any additional values in the CSV file will be rejected.
•
If the CSV file contains values of the wrong data type, the configured default value is set
in the recipe record.
Example:
The CSV file contains values that show the tank contents and were input as floating point
numbers. However, the corresponding recipe tag expects an integer value. In this case,
the system discards the imported value and uses the configured default.
•
The system also applies the configured default value to the recipe data record if the CSV
file contains an insufficient number of values.
10.6.6 Reactions
to
modifications of the recipe structure
Introduction
Engineering for the purpose of machine retrofitting may also influence the recipe structure.
Previously created recipe data records can nevertheless continue to be used.
Effects
If the structure of the recipe record is different from the defined address ranges in the PLC,
deviations are handled as follows:
•
Any additional values in the recipe record will be rejected.
•
If the recipe record contains values of the incorrect data type, the default will be used in
the recipe record.
Example: The recipe record contains values that show the tank contents and were input
as floating point numbers. However, the corresponding recipe tag expects an integer
value. In this case, the transferred value is rejected and the default value is used.
