Preliminary Remarks

Notes for the reader: The SINUMERIK documentation is organized in 4 parts:

• General Documentation

• User Documentation

• Manufacturer Documentation and

• Service Documentation

This manual is intended for OEM customers and manufacturers of machine tools who use the SINUMERIK 840C OEM Version for Windows.

The software of the integrated MMC of the SINUMERIK 840C OEM Version for Windows includes the operating systems:

• MS-DOS 6.22

• MS-Windows for Workgroups 3.11 (WfW 3.11)

• FlexOS

The control can be started up both under Windows for Workgroups

3.11 and FlexOS. If FlexOS is booted, the control is functionally identical with the SINUMERIK 840C/CE (basic version).

Booting under WfW 3.11 provides the OEM customer or machine manufacturer with a way of integrating his own technological expertise into the control under a widely used operating system platform. Moreover, with MS Windows it is possible to make use of the wide range of inexpensive software for technical and industrial applications on the control.

This manual describes the method of operation and parameter options of the internal software modules of the integrated MMC and provides the user with the information required to develop and integrate his own applications into the software system.

This manual is intended to be introductory, so the reader does not need any special knowledge except for experience of NC technology and a basic knowledge of how to program the MS Windows operating system.

For the acquisition or improvement of knowledge of these subjects, we recommend the training courses provided by SIEMENS. Please consult your local SIEMENS branch office or national company for further information.

09.01

The Manufacturer Documentation for the 840C control is subdivided into the following parts:

• Function Macros

• Planning Guides

- Package 0: Basic Functions

- Package 1: Tool Management

1 Introduction

More and more often machine tool manufacturers are faced with the task not only of developing standardized machine tools but also special solutions for manufacturing technology. In particular, higher and higher demands are being placed on the functionality of a CNC control. The demands are often machine-specific and cannot be fully covered by standard products.

On the other hand, there is a desire to use the freedom afforded by the control to give it its own appearance and/or include technological know-how. Previous man-machine interfaces (MMC) were mostly based on control-specific software systems and demanded special knowledge of the solution in question. A further disadvantage of such systems is their "closed" character which often means that function expansions can only be included with great effort.

Today, there is a demand for "open-ended" control systems. This applies not only to the user interfaces and the operating system but also to the entire computer hardware. To meet this demand, SIEMENS has developed the SINUMERIK 840C OEM Version for Windows, an AT compatible MMC that is based on the "open" operating systems MS-DOS 6.22 and MS Windows for Workgroups 3.11.

The MMC variation permits the use of numerous commercially available hardware modules in conjunction with the AT box and therefore the integration of existing hardware solutions directly into the control. The applications of such solutions include:

• Remote diagnostics

• Measuring data acquisition for quality assurance and process control

• MDA/PDA systems (machine and production data acquisition)

• DNC systems (program management and transmission)

Moreover, it is possible to benefit directly from the advantages of the broad range of industrial and commercial software available. This means that the same programming workstation software with the same user-friendliness can be used both on an external PC during work preparation and directly on the control.

For customer developments, Windows for Workgroups 3.11 provides a reliable and stable platform and a minimization of compatibility problems in the future. Moreover, this operating system ensures great flexibility and cost-effective network-capability for the entire control system. With the pr ogramming tools available on the market, the machine-tool manufacturer has the option of developing his own applications and integrating them into the control.

With Visual Basic for Windows, Microsoft has developed a programming tool that cleverly combines the advantages of Windows with the programming language Basic. There is scarcely another programming system with which it is so easy to write Windows programs. Using predefined "Custom Controls", even a beginner can develop professional Windows user interfaces in a simple way. Windows and menus can be opened and closed with simple program commands and the input and output of the program user can be managed and visualized.

However, anyone aiming at professional development cannot do without Visual C++. C++ is currently the first choice when it comes to solving complex programming problems in a simple way. With visual C it is possible not only to write programs for Windows but also under Windows, and that faster and more easily then ever before. Integrated tools such as AppWizard and ClassWizard save the programmer a lot of time-consuming and error-prone administration work, allowing him to concentrate on the actual problem to be solved.

1 Introduction

09.01

Windows applications can exchange data with the NCK, PLC and 611D via the DDE interface defined by Microsoft (Dynamic Data Exchange). Via the DDE server, which is also part of the OEM package, data are transferred from the applications and from and to the NCK, PLC and 611D. The methods "POKE" (write data), "REQUEST" (read data) and "EXECUTE" (commands for file transfer) are implemented. Towards the PLC the "ADVISE" method is also implemented. The data that can be accessed via the DDE server include machine data, setting data, PLC data blocks, part programs etc.

Simply by entering applications in an initialization file, they are integrated into the area switchover and can be started either automatically when the control is booted or by the user by means of softkey or PLC command. Examples of such customer applications include:

• Tool management and visualization

• Pallet management

• Job management

• Machine diagnosis

With the OEM package, the machine-tool manufacturer obtains not only the DDE server and a few library routines but also a complete simulation and test environment for an external PC. With a commercially available programming tool (e.g. Visual Basic, Visual C++, etc.) the machine-tool manufacturer can develop and test his own applications on an external PC.

The following section of this documentation deals with the requirements for and the installation of the OEM test environment and the OEMFORM alarm tool.

Chapter 3 provides a system description of SINUMERIK 840C OEM Version for Windows. This description includes both the hardware architecture of the control and the method of operation and parameterization of the Siemens basic modules.

The alarm concept described in previous editions in Chapter 4 has been taken out to form a separate documentation from the current software version on.

The next section contains a brief introduction to the method of operation of the Windows DDE and a detailed discussion of the various communications options of OEM applications with the NCK and PLC.

The DDE section is completed with a description of some sample programs that show the reader how to integrate his own applications and serve as a guide for the development of custom applications.

2.3 Additional notes on the OEM t est environment

• When you copy the keyboard drivers you might find that Windows is currently using one of

these drivers. You can acknowledge the message that appears on the screen with the button "IGNORE".

• The font in the editor "WEdit" might differ slightly from the font on the control. An

equivalent font is not loaded in the test environment.

• The OEM test environment has been developed for a VGA resolution of (640×480 pixels).

If you use a higher resolution, the OEM test environment uses an equivalent portion of the full screen. The OEM test environment is, however, still fully functional.

• The softkey bar that displays the menu list for the application currently active can be

hidden by calling the softkey manager SOFTMAN.EXE again in directory C:\MMCWIN\PC.

• The appearance of several applications can be altered in the installation file SIN840C.INI

(see Section 3.5) in directory C:\MMCWIN\PC. The window size and foreground/ background behavior of applications can be altered with the following options:

- Window always on top: topmost=on/off

- Window size: position[ ... ]

• In the MACHINE basic display of the test environment, the 1st softkey on the NC control

panel corresponds to function key F2. In all other applications, the 1st softkey corresponds to function key F3.

2.4 Directory structure of the OEM test environment

When you have installed the OEM test environment you will find the following directory structure on drive C: of your hard disk:

mmcwin — — PC

englis

The OEM test environment contains the following subdirectories:

• Directory "local". This directory contains the workpieces that have been created

(subdirectories) together with all the files (mpf...,spf..., toa, etc.) required for machining a workpiece. This directory is also part of the system software of the contr ol. After installation, only the workpiece with the name "standard" exists.

• Directory "md" usually contains the machine data of the control. As no real NCK or PLC exist

in the OEM test environment, the associated subdirectories are "empty", i.e. they only contain the obligatory "dummy" files. Both the workpieces and the directory with the machine data can be selected and edited under the data management of the OEM test environment.

• Directory "mmcsrc" contains a number of sample programs including all the source and

resource files. These sample programs are intended to provide you with help in developing your own applications.

The sample programs have either been developed with Microsoft Windows 3.1 SDK or MFC 2.0 (C:\MMCSRC\MSC) or with Microsoft Visual Basic 3.0 (C:\MMCSRC\VB). They are available either as executable *.EXE files or as entire projects with resources, source code, libraries and header files. The sample programs VSASER.EXE, ADVTEST.EXE and TACHO.EXE are already linked into the OEM test environment and can be started directly from it. You will find a description of the sample programs in Chapter 6.

• Directory C:\MMCWIN\PCMCIA contains 3 com driver floppy disks, XIRCO M driver floppies

and PC-CARD HD Patch.

• Directory C:\MMCWIN\PC contains all the basic modules of 840C OEM Version for Windows.

This directory exists both in the OEM test environment as well as in the contr ol. In addition to the basic components such as area switchover, data management, the editor "WEdit" etc., this directory contains the actual DDE server (DDESRV.EXE) for linking Windows applications to the NCK, PLC and 611D. This directory also contains a multiport RAM simulator (MPRSIM.EXE) for PC use. You will find a description of the basic modules in Section 3.3.

• Directory \mmcwin\pc\bild contains the machine displays that are displayed in the OEM test

environment when a machine area is called.

3.1 Overview

The product SINUMERIK 840C OEM Version for Windows provides the machine-tool manufacturer with a sophisticated and modern control which is used as a basis for integrating additional function expansions and customer-specific solutions.

3.1.1 Hardware concept

The following hardware configuration was chosen to meet the demands for "open architecture" and adaptability.

NCK PLC

A T-compatib le PC

Fig. 3.1: Functional st ructure of SINUMERIK 840C OEM Version for Windows

The CNC 840C control can be divided into the following three components: MMC=PC: With this integrated AT-compatible PC with the operating system Windows for

Workgroups 3.11, the machine-tool manufacturer can make individual adaptations and develop his own solutions on all levels of the user interface (MMC=Man Machine Communication) including communication with the NCK and the PLC. The AT box of central controller 3 also provides the user with open architecture hardware.

NCK: The actual NC kernel works with a 32-bit word size and an NC memory of 1 MB.

Up to 6 spindles can be operated from its 15 servo loops. Several programs can be executed simultaneously due to its channel structure. Data can be exchanged with the MMC and the PLC via the DDE interface and the VDI interface. Using program package WS800 A, machine displays can be configured in the NCK and customized machining cycles created and the control therefore adapted to the individual tasks of the machine tool.

PLC: The PLC section of the SINUMERIK 840C is responsible for the entire machine

control and always contained the essential know-how of the machine-tool manufacturer. 1024 inputs and outputs, a 256-KB user memory and a processing speed of less than 1 ms per 1000 instructions are the salient features of the freely programmable PLC.

3.1.2 Software structure of the integrated PC

The system software of the CNC control 840C OEM Version for Windows comprises the 840C system software basic version (FlexOS) which has been expanded by a Windows MMC. The OEM test environment essentially consists of modified MMC Windows software installed on the hard disk which enables simulation of the Windows SINUMERIK 840C interface on an external PC. The diagram below shows the distribution of the entire control software on the hard disk.

Fig. 3.2: Main divisi on of the software on the hard disk of the 840C OEM Version for Windows

1. The installation functions (MD dialog, drive/servo installation) in the Diagnosis area can only be executed under MMC FlexOS. The operating system FlexOS can be selected in the backup/restore menu.

Common software includes DOS, Valitek and NCK, PLC and drive software. This software r uns

with the Windows MMC without any restrictions.

The Windows MMC consists of the operating system Windows for Workgroups 3.11 and a

3. Windows basic system (basic modules) which, like the basic version (FlexOS), is responsible for the basic functions of the Windows control panel and operation. The user can also install the software in the five standard languages (English, German, French, Italian and Spanish) and switch between the individual languages.

The DDE server (Dynamic Data Exchange) is the data interface to the NCK, PLC and 611D. The

DDE server is both part of the OEM package and the control software. However, it can only be executed with the library MEMBER.DLL supplied with the OEM package.

The user area can be used both by the machine-tool manufacturer and the end user. The OEM

5. can use the part of the hard disk that is not used by Siemens which is paid for when the MMC Windows licence is purchased. A memory size of at least 40 MB is guaranteed. As it is possible to integrate OEM software under Windows, space on the hard disk is provided for customized programs that can be developed using commercially available tools.

The user area can also be used for end user data such as part pr ograms, measurement data,

order data, MDA/PDA data etc.

The individual operating system components, as well as the Siemens basic modules and the OEM applications can interact as shown below and exchange information with the NCK/PLC and the 611- D. Fig. 3.3. clearly shows the interaction between the Windows system software and the basic modules and OEM applications.

1. The machine displays created in the NC kernel with WS800 A are passed directly to the user interface via a graphics converter (NCK task), i.e. the operator receives the information directly from the NCK/PLC and 611-D. Conversely, (nearly) all the entries made via the keyboard on the control panel or the MF2 keyboard are passed onto the NCK.

In addition to the NCK task, other Siemens basic modules carry out numerous functions in the

MMC area. The area switchover is therefore used to start additional applications and the data management to manage the files on the hard disk and to transfer data between the MMC and the NCK or peripheral device.

The OEM applications like the Siemens applications (e.g. machine operation, parameters, etc.)

are initiated via the area switchover. Some of the basic modules also contain special function calls (e.g. workpiece transfer via serial interface) which can also be used by OEM applications. The OEM applications can be operated in the usual way via the operator panel or keyboard.

Data on NCK, PLC, 611D is accessed using the DDE server via the DDE interface defined by

4. Microsoft. This interface is supported by nearly all Windows programs (EXCEL, WORD, etc.) and development tools (MS-Visual Basic, Visual C++, etc.) and guarantees a high degree of development safety and stability due to its fixed definition and widespread use.

OEM applications can also directly access services in the DOS/Windows oper ating system. File

manager, printer, Windows API (Windows Application Programmers Interface), etc. calls can be used in the usual way.

3.1.3 Basic modules

The MMC Windows basic system together with the operating system are r esponsible for operation of the integrated PC. The MMC Windows basic modules and the OEM test environment are largely identical. All the standard modules have a compatible structure and a uniform appearance which can be modified by making entries in the initialization files. Basic modules that run in the background (e.g. multiport RAM driver, keyboard driver, DDE server etc.) are configured in such a way that they do not appear in the task list. This ensures that the user only accesses applications that he can see in the task list.

The following diagram provides an overview of the most important modules in the basic system

• Individual applications can be started by the operator via softkey with the area switchover (REGIE.EXE) which replaces the Windows program manager. It is activated via the data area key. As far as the area switchover is concerned, the Siemens areas, "Machine", "Par ameter", ..., are ordinary applications.

The menu line and the entries in the associated pull-down menus including the application to be initiated (*.EXE files) can be freely defined in the initialization file (REGIE.INI). Applications can also be protected with a password, keyswitch position and cycle disable. The area switchover is preconfigured by Siemens and can be changed as necessary (e.g. removing the Machine area and adding OEM applications). It can be operated either via the control panel keys, softkeys or mouse.

• NCK task (NCKTASK.EXE) groups together the entire control of the NCK. Th is includes both the display of graphic information that is processed in the NCK area as well as the transfer of keyboard entries to the NCK. NCK task is also responsible for managing the current menus of the various data areas of the NCK. In the OEM test environment where ther e is no link to an NCK, NCK task visualizes machine displays that are stored on the hard disk.

• The data manager (DATENMAN.EXE) contains a user interface for transferring files between the MMC, NCK, diskette drive and serial interface. A workpiece manager and an editor "WEdit" (WEDIT.EXE) with which part programs can be edited directly in the NCK memory are also provided.

With the workpiece manager it is possible to integrate network drives, making transparent selection of workpieces that are stored on a remote computer possible. "Part program execution from the hard disk or network" is also implemented. Files can also be edited directly in the NCK memory with the editor.

• With the Parameterization V24 module (PAR_V24.EXE), serial interfaces can be par ameterized for the transmission of data in tape format. Up to 10 interface settings can also be managed.

• The alarm module (ALARM.EXE) accepts alarms and messages from the NCK/PLC/drive, visualizes them in the alarm or message line and lists the current alarms and messages in the alarm window. The position at which the alarm is displayed on the screen is defined in the alarm text database. An OEM application can obtain the current active alarms and messages via the Windows DDE mechanism (Dynamic Data Exchange) and initiate its own.

• The NCK/PLC communication essentially consists of the DDE server (DDESRV.EXE) and the MPR server (SERVER.EXE) which allow the modules described above and the OEM applications to exchange data with the NCK/PLC and the 611D. In the OEM test environment, the multiport RAM server is replaced by an MPR server simulator (MPRSSIM.EXE).

• The softkey manager (SOFTMAN.EXE) displays the menu line of Windows applications and the buttons of non-system modal dialog boxes on the horizontal softkey bar. It is thus also possible to operate any Windows application via softkey.

• The keyboard driver (KYRU.EXE) converts signals coming from the 840C operator panel into codes which can be evaluated by Windows or DOS. This same thing happens when a full MF2 keyboard is connected to the operator panel. A keyboard can only be connected to the central controller for OEM servicing because of the lack of EMC of the keyboard connection.

The user can also freely assign various keys on the NC operator panel.

• Data can be saved and read back in via the Valitek streamer or via PC link as on the 840C Basic Version. The streamer is connected to the parallel interface of the MMC CPU module. You must close Windows and return to the MS DOS level to operate the streamer.

3.1.4 NCK / PLC / SIMODRIVE 611-D interface

Data/files of the NCK/PLC/611D are accessed via the DDE interface (Dynamic Data Exchange) defined by Microsoft for Windows applications. The DDE server collects the data and makes them available to the applications. The functions "POKE" (write data), "REQUEST" (read data) and "EXECUTE" (commands for file transfer) are implemented. The function "ADVISE" is also implemented for the PLC.

Data exchange with standard Windows programs such as Excel, Visual Basic, etc. is possible via this interface. The DDE server can access, for example, machine data, setting data, PLC data blocks, part programs and current values.

Fig. 3.5: Data exchange via DDE server

The DDE server converts the data request into an I code protocol and passes it on to the NCK. There, a software module sends the requested data to the DDE server.

Two function blocks exist in the PLC, FX74 (read data from DDE server and write to a data block) and FX73 (read data from a data block and write to the DDE server). The user can fr eely select the for mats and the protocols. For this, he must write a function block that reads out the data with the help of FX74, interprets them and writes back the requested data with FX73.

Service and drive data can be accessed for the SIMODRIVE 611-D. The DDE server is only used for data exchange and is not a control interface.

You will find a detailed description of the DDE server and the I code interface with its various features in Chapter 5 and Appendix A1.

The PC integrated in the 840C OEM Version for Windows provides all the functions of an AT motherboard. The entire set of chips of an AT is integrated on one printed circuit board, which gives rise to the name SBC (single board computer). The SBC is an industry-standard and noise-fr ee ver sion of an integrated industrial PC. It is linked to the internal SINUMERIK bus via a dual-por t RAM and via this link is able to exchange data with the NCK, PLC and SIMODRIVE 611-D.

An MMC interface module can be slotted into the central rack directly next to the MMC CPU module via the AT96 bus. This module has two additional serial interfaces, two PCMCIA slots (type II) and a floppy bus extension for connecting diskette drive FD-E2.

Central controller 3 also contains an AT box whose ISA bus is linked to the AT96 bus. A maximum of 3 standard 16-bit PC cards can be slotted into this AT box, providing the user with many options for connecting peripherals (networking via standard PC modules) or integrating existing external solutions directly to the control (measuring computer for quality assurance).

In contrast to a standard PC, however, the integrated SBS of the SINUMERIK 840C does not have a loudspeaker.
