Sections

Within the target areas (NC data, SINAMICS data, display data), the structured data is
addressed via specifying a section. Set sections act local to a script until another section is
set or the script (task) ends.
For details, see section Data accesses (Page 333).
Set section - [B?_S?_PS?], [SL], [C?], CHANDATA(?)
For data with the same name, which occur in various areas, before assigning a value, a
specifying section must be specified. This section is effective as long as no other section is
specified. Data accesses between areas are unaffected by this.
When no channel is specified for NC data, then channel 1 is assumed.
The following section data is permissible depending on the target area:
