Configuration Of Recipes - Siemens SIMATIC TP 270 Operating Instructions Manual

Operating recipes
10.4 Recipe application
The HMI device stores recipe data records on a storage medium such as a flash memory
device or hard disk. You can edit a recipe data record in a recipe view or recipe screen on
the HMI device display.
(1) Save: Values you change on the recipe view or recipe screen are written to the recipe
data record on the storage medium by executing the "Save" function.
(2) Load: The "Load" function is used to update the values of recipe tags shown on the
recipe screen with the values of the recipe data record on the storage medium. The function
overwrites any values changed on the recipe screen. The "Load" function is executed for the
recipe view when the data record is selected again.
(3) To PLC: if you change values in a recipe view and recipe screen, download the changes
to the PLC with the "To PLC" function.
(4) From PLC: Use the "From PLC" function to update the indicated values of the recipe view
and recipe screen with the controller values. The function overwrites any data changed on
the recipe view or screen.
(5) Synchronization with controller: In your configuration, you can decide to synchronize the
values in the recipe view with the values of the recipe tags by setting the "Synchronization
with controller" function. After this synchronization, both the recipe tags and the recipe view
contain the current updated values. When the "Variables offline" setting is disabled for the
recipe, the current values are also applied in the controller.
(6) Import, Export: A data record can be exported to an external storage medium and edited,
for example, with MS Excel. The data record is saved in *.csv format.
