Structured step sequence display (option)

Function
You can either edit a part program in the ASCII editor (standard
display) or in step sequence display ("Sequence" softkey).
Configuring the SEDITOR.INI file enables NC programs to be
displayed in a structured manner without changing the program. In
addition, the "SEFORM()" instruction can be inserted for a structured
step display.
The step view improves the readability of the NC program.
Step sequence display has the following advantages:
• Quicker sequence detection
• Quicker navigation
• Easier sequence editing (block functions at step level: e.g.,
modifying the sequence)
• Single keystroke (Recompile or Input) to access the standard
ASCII editor environment (ASCII or dialog with support functions
such as cycle screens, contour calculator).
If you have created your own user cycles, which you use regularly in
several programs and want to display clear steps, please contact your
machine supplier so that a user-specific SEDITOR.INI can be placed
in the user area for you.
Specific keywords stored in the configuration file are searched for in
the ASCII program of the loaded program. These are then assigned to
the primary level or secondary level to create a structure for the step
sequence display. As a result, a structured display can be achieved in
so-called step sequences without changing the ASCII program. The
special display of control structures such as IF, THEN, ELSE, GOTO,
CASE, FOR, WHILE, etc., has not been considered here. Using the
SEFORM instruction it is possible to achieve additional structures in
the program, if required. Pressing the keys CTRL + I will insert a
predefined SEFORM instruction in the SEDITOR.INI.
The configuration file stores the following information:
• Which single or multi line sequence is recognized as a step (e.g.,
cycle call, contour element, WAITM call)
• Which step identifier and which symbol is displayed instead of
the recognized sequence
• To which level (0-Primary level/1-Secondary level) a symbol and
to which step identifier the recognized sequence should be
assigned.
