"Program" operating area 6.1 Program types
6.1 Program types
6.1.1 Part program
A part program consists of a sequence of instructions to the NC control. In its entirety, this sequence affects the production of a specific workpiece or a particular machining process on a given blank.
6.1.2 Subprogram
A subprogram is a sequence of instructions in a part program which can be called repeatedly with different defining parameters. Cycles are a type of subprogram.
6.1.3 Workpiece
- A workpiece is a part to be produced or machined by the machine tool or from the HMI perspective is to be produced or machined.In the HMI, a workpiece is a directory in which programs and other data for machining a particular workpiece are stored.
6.1.4 Cycles
Cycles are subprograms for the execution of a recurring machining process on the workpiece.
6.1.5 Storing programs
Programs can be saved in the NC memory or on hard disk. The currently available memory space is displayed in the user response line. Cycles can also be stored in the NC Flash File System.
6 "Program" operating area 6.1 Program types 01/2008 6
6.1.6 Templates
Templates are objects that can be used for creating new workpieces, part programs, subprograms, job lists, work offsets, etc. and can be edited and customized to suit the task at hand. With HMI Advanced, templates for job lists are stored in the file system by default. Specific user templates must first be created in template directories. This allows you to access them when creating new objects. Templates can be designed in different languages and named to allow easy language-specific access to them. If you create a template with a wildcard in the name, the current workpiece name will be inserted into the name when the template is activated.
There is no difference between creating templates and creating workpieces, part programs, subprograms, job lists, work offsets, etc. You can use the administration functions and naming conventions to enter objects you want to use as templates in the template directory. Templates can be created from the Services operating area directly in the required directories. Existing templates are offered for selection when you create new objects.
Naming conventions for templates
TEMPL If this string is assigned as part of the template name, it is replaced by the workpiece name when the template is activated. The template is not copied if the name exceeds 24 characters after replacement.
_XX If the template name terminates in _XX (XX stands for the language code, e.g., _GR for German), only the objects are offered from the template directory where the current language matches the language code in the template name. Templates for different languages can therefore be stored together in the template directory.
1_1 If the template name starts with 1_1, the template is proposed for standard configuration.
M_N If the template name starts with M_N, the template is proposed for M:N system configurations (netnames.ini is configured). 1_1 or M_N can be combined with _XX.
6 01/2008 "Program" operating area 6.1 Program types 6
Additional information
Language-specific templates are given priority over non-language-specific templates with the same core name component. Therefore, you can create a template which can be used for all languages for which no language-specific variants are available.
Directories for templates
The Services operating area contains the following subdirectories under Templates: Users Empty when shipped Vendor Empty when shipped Siemens Standard job lists provided when shipped
Templates Empty when shipped
If the Templates subdirectory for this data type is not empty when creating a new data type, you can enter "No template" to access the templates in the user, manufacturer and Siemens directories.
User, manufacturer and Siemens templates are available for individual file types under: Commissioning \rightarrow HMI \rightarrow System settings \rightarrow Templates The activation differs according to: – Job lists – Initialization programs – Part programs/subprograms –
In the Templates directory, you can store:
- Individual templates for various data types and
- Complete workpieces as templates in a subdirectory. The full workpiece templates are offered for selection when data type WPD is newly created. If selected, all components belonging to the template are copied to the new workpiece in accordance with the above naming conventions. With other data types only the selected template is used.
Create templates
In the Services operating area select the directory for which you are authorized. Templates/Users /Manufacturer /Siemens /Templates
Define the name, data type and - if required - template. Confirm with OK. Use the editor to process the created template.
6 "Program" operating area 01/2008 6 6.2 Main screen program
Save templates You can use the administration functions to copy and paste template objects to the directories and use the above mentioned naming conventions to rename the templates e.g., for specific languages or workpiece names.
You can save existing templates under Services "Data out" or read saved templates back in with "Data in".

<< When you branch to a workpiece, the "<<" softkey automatically appears to allow you to return to the main menu.
6.3 Edit programs iin the standard ASCII Editor
Function
The default editor for creating and editing part programs or other text files is the standard ASCII editor. This allows users to edit part programs using individual instructions: G codes, keywords, etc.
The version with two windows displaying two sets of program instructions side-by-side is referred to as the "Dual ASCII editor" (dual editor).
- The standard ASCII editor displays the characters that can be entered via the keys on the operator panel.
- A part program opened by the editor cannot be simultaneously started in the NC (enable is canceled); an alarm (14011) is indicated in this case. If the control is switched off while the editor is open, the enable might have to be set manually.
- When you exit the editor after editing cycles in the NC and if these cycles are also stored in the Flash File System, then an activity symbol (fan symbol) is displayed while the data is being copied into the Flash File System.

6.3.1 Undo and redo in the standard ASCII editor
Function
Edit When editing a part program or a text file, you can undo complete blocks in the editor:
- Press "Ctrl" and "Z" for "Undo" (reset)
- Press "Ctrl" and "Y" for "Redo" (reactivate)
Once you undo a series of blocks, you can redo the same number of blocks. Both functions only apply to programs that are not loaded.
Sequence of operations
"Ctrl" + "Z" Press the key combination "Ctrl" + "Z". All changes in the entire block are undone. Repeat the key combination to undo the previous change. The "CR" symbol at the end of the block is also considered. This procedure can be repeated until the last change or the set number of changes has been reached.
"Ctrl" + "Y" Press the key combination "Ctrl" + "Y". The last changes undone in the editor are redone. This procedure can be repeated until the last change is redone or the set number of maximum changes has been reached.
The default number is 10 steps; this setting can be changed. Setting the number to zero deactivates the function.

6 01/2008 "Program" operating area
6.3 Edit programs iin the standard ASCII Editor
6.3.2 Additional optional editors
Step editor display (option) As an option, the single step sequence display can be used with extended functions. These extended functions allow you to process technology-oriented program steps which are stored and displayed with special icons in the editor for each step type to enable easier recognition. The steps must be defined in the SEDITOR.INI file:
- Groups of individual instructions: G codes, keywords, etc.
- Synchronization instructions (e.g. WAITM)
- Cycles
- Contour definitions
Advantages:
- Improved readability of programs
- Operations based on steps (copy, insert, delete etc.)
- Recompilation from step to DIN code, contour definition and cycle display available
- Step sequence displays form the basis for the multi-channel step sequence programming
See Section 6.7 Structured display in the step editor (option)
Multi-channel step sequence programming (option) Multi-channel step sequence programming is available as an option and offers the following features:
- Simultaneous display of several programs for a workpiece in multiple channels
- Optional fixed step lengths or time proportional display of step lengths in the channels
- Display of processing duration for steps and waiting time at synchronization points
See Section 6.8 Multi-channel step sequence programming (option)
6.3.3 Selective program protection RO
Function
In programs written with program templates or when using the programming support functions, certain machine-specific code lines may be protected against changes.
A read-only identifier (";RO") is tagged onto the code program blocks as a comment.
6 "Program" operating area
6.3 Edit programs iin the standard ASCII Editor
The user can always identify protected program sections by the "Read Only" identifier (";RO"). Any attempt to change a program part protected by the read-only identifier is denied with the message "Block cannot be written".
Example The ASCII editor recognizes these blocks, hides them or displays them in the read-only text color (gray), and prevents changes to these blocks.
Reserved character strings Reserved character strings occur in part program code lines which are generated by calling cycles and programming contour definitions. They can be viewed by setting "Display hidden lines" in the editor.
The following character strings must not be used in part program lines that are directly input: ;# ;#END ;NCG ;RO ;HD
Additional information When creating a program template, remember to position the "Read Only" identifier directly at the end of the block.
6 01/2008 "Program" operating area
6.4 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.
Advantages:
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.
Structure
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.
