Formula Management in the PLC

Disables the following options: “Save Formula,” “Load Formula” and “Overwrite Existing Formula on Download.”

A POU (Programming Organization Unit) is created in the runtime system for formula management.

2

Save Formula

Automatically Save Formula Changes to the Formula Files

Does not automatically save changes.

Automatically saves formulas to a file after a change.

3

Load Formula

Only Load If Variable List Matches Exactly

Loads a formula file only if it contains all the variables from the list of variables of an application’s formula definition.

Load Variables with Matching Names

All matching variable names are loaded from the formula file.

Note:
No notification is given if there are differences between the formula file and the formula definition of an application.

4

Overwrite Existing Formulas on Download

Existing formulas are not overwritten when a new application is initialized.

Existing formulas may be overwritten when a new application is initialized.

5

Write Formula

Limit Variable to Min/Max
If Formula Outside Range

If the formula contains a value outside the value range entered in the definition, the specified minimum or maximum value is written to the PLC variable instead of this value.

Do Not Write Variable If Formula Outside Min/Max Range

If the formula contains a value that is outside the value range entered in the definition, no value is written to the PLC variable. It retains its current value.

6

Check Formula for Changes

Formula is saved without additional checks.

Generates additional code to save a formula only if it is changed by using “ReadAndSaveRecipe.”
