10.7.5 Reading a recipe data record from the PLC
Introduction
The values of recipe elements are exchanged with the PLC via tags.
In the current project, the values which are also stored in the recipes in the HMI device can
be changed directly in the plant. This is the case, for example, if a valve was opened further
directly at the plant than is stored in the recipe. The values of the tags on the HMI device
possibly no longer match the values in the PLC.
To synchronize the recipe values, read the values from the PLC and display them in the
recipe view.
Requirements
A screen with a simple recipe view is displayed.
Procedure
Proceed as follows:
1. If the recipe list contains several recipes: Select the recipe which contains
the desired recipe data record.
2. Select the element list of the recipe data record to which you want to apply
the values from the PLC.
3. Open the menu.
4. Select the menu command "2 from PLC".
The values are read from the PLC.
5. If you want to save the display values in the HMI device, select the menu
command "0 Save".
Result
The values were read from the PLC, displayed on the HMI device and saved to
the selected recipe data record.
