Programming
2.1 Getting started
Start softkeys
One or more softkeys (start softkeys), which are used to initiate your own operating
sequences, are defined in one of the specified configuration files.
The loading of a dedicated dialog is associated with a softkey definition or another softkey
menu. These are then used to perform the subsequent actions.
Pressing the start softkey loads the assigned dialog. This will also activate the softkeys
associated with the dialog. Variables will be output to the standard positions unless specific
positions have been configured.
Reverting to the standard application
You can exit the newly created user interfaces and return to the standard application.
You can use the <RECALL> key to close new user interfaces if you have not configured this
key for any other task.
Calling your own dialogs from PLC
Dialogs can be selected via the PLC as well as via softkeys. An interface (in DB19) is
available for signal exchange between the PLC and HMI.

2.1.2 Configuration and start files
Overview
Every application uses permanent (HMI Embedded sl, ShopMill, and ShopTurn on NCU) or
preset (HMI Advanced) start softkeys, which can be be used to access newly generated
dialogs. Additional start softkeys can be configured with HMI Advanced.
Other files:
In the event of "Load a screen form" (LM) or a "Load softkey menu" (LS) call in a
configuration file, a new file name containing the object called can be specified. This makes
it possible to structure the configuration, e.g., all functions in one operation mode in a
separate configuration file.
