Siemens SINUMERIK 840D sl Operating Manual page 301

The step configuration is configured for each step individually, either via the context menu or
via the settings of the property field.
Note
Step activation
The step activation can also be configured direct in the step tree and becomes effective
immediately.
Execute step(s) - Up.$Step[id].Processing
Using the system variable Up.$Step[id].Processing, the execution status for package
execution is defined in the step tree.
System variable Up.$Step[id].Processing supplies the value "true" for all steps whose step
symbol (option button or checkbox) has already been activated and are displayed in green.
The selected step in green and all of its higher-level steps are performed during package
execution. Activated substeps are marked in green and are thus executed if the higher-level
step is activated. The step in the first level is always assigned the execution status during
activation.
The value "false" is returned for all other step symbols with a white background.
