WintDrive 1. lntruduction Win+Drive is a graphic programming tool for the Windows TM operating system. Programs can be built by the graphic assembly of blocks which represent pieces of program code. Win+Drive is especially useful for designing the software of control systems. The tool generates C code that can be compiled and run on different target platforms including the PC itself. I.1 About this Manual This manual decribes how to install and to use Win+Drive.
GEL100340 12 Document Conventions Within this document the following visual orientation help are used: 1.3 Font Function Bold Names of menus, commands and register cards. Italic Items to input (i.e. filenames). SMALL CAF’ITALS Key codes. Fixed Code examples, contents of text files. spacing Installation of Win+Drive The Win+Drive environment is composed of three elements : is the base software of the graphic editor and contains the New Project tool to - WlN+Drive create a project.
WintDrive 2 D e v e l o p i n g a Win+Drive A p p l i c a t i o n 2.1 What is Win+Dfive? The control of systems by electronics was traditionally done by analog circuits. These analog circuits operate continuously. Their structure can be described by block diagrams based on general blocks like PI controllers, adders etc. Using digital software control by microcontrollers for the same control tasks is possible in many cases.
GEI-100340 2.3 The Development Process Figure 23.1: Design Flow The total process for developing a Win+Drive application consists of the following steps: 1. Create a new project. 2 . Create the schematics by placing basic blocks and connecting them. This is done using the schematic editor. If complex projects have to be created you can create compound blocks to insert hierachy into your project. 3 . Generate code from the schematics and compile them for the PC as the target system. 4 .

It contains the following items: m starting Win+Drive - starting the Image editor - opening the Win-tDrive help - uninstalling W&Drive Files with the extension. WDR will be associated with the Win+Drive application. 4.1.
WintDrive 4.4 The Win+Drive Screen Layout The Win+Drive screen layout closely resembles the layout of Windows MD1 applications (Multiple Document Interface) like Microsoft Word or Excel. The main window includes a menu bar, a toolbar and a block selection bar at the top and a statusbar at the bottom. Between these bars there is the client area where one or more child windows can appear.
GEL100340 4.4.3 Block Selection Bar The block selection bar provides quick access to the building blocks of the schematics. It is divided into two parts: the left part is used for selecting a group. The members of the selected group are displayed on the right half of the bar. Placing of a block is done by dragging and dropping a block into the schematic. The block selection bar can be made hidden or visible by the menu item Block Toolbar of the View menu. ;J CtB fTJ Zag CM GasB&y c&j ah emwmf! Figure 4.4.

Alternatively a dialog for searching help on a specific topic can be opened. Another menu item is provided for getting help on how to use help. Context-sensitive help is implemented in Win+Drive. Key ~1 can be used to open a help topic that corresponds to the actual situation of the user.
WindI rive 5. C r e a t i n g Software Schematics Building programs using Win+Drive is very similar to creating electrical circuit descriptions. It consists mainly of two actions: - selecting and placing blocks of code onto the schematic - and connecting these blocks. 5.1 Placing Software Blocks Figure 5.1: Block A block is always the representation of a specific function that is performed by a piece of code.
GEI-100340 5 1.2 Placing Blocks using the lnserf Menu To select a block from the Insert menu act as follows: - first open the Insert Menu and select the appropriate group. Now a submenu is opened showing the members of this group. - select one of them by clicking the menu item. The cursor changes to a symbol representing a basic block. - move the mouse to the place the block shall be inserted - then click the left mouse key.
WintDrive 5.3 Placing Text and labels In order to have comments on a schematic for explanation texts and labels can be placed. Both have no function for the code generation and are provided only for readability. Texts and labels are nearly identical; the only difference is that labels are linked to blocks while texts are not. 53.1 Placing a Text For placing a text perform the following actions: - select the menu item Text from the Insert menu. The cursor changes to four arrows pointing to the middle.
GEL100340 5.4 Editing the Ports of Blocks Section 5.2 above explained that the ports of blocks represent input and output variables of the underlying piece of code and that these ports can be connected together. Drawing a connection line is the most common operation on the ports of blocks. Other operations are available by opening the ports dialog. 5.4.
Win&rive 5.4.3 Setting the Port Attributes The port attributes consist of two properties: - the name of the port - the data type of the port. The name cannot be changed for basic blocks, only for compound blocks. The data type can be set to the standard types of the C language: - char - short - int - long - Uchar (unsigned char) - Ushort (unsigned short) - Uint (unsigned int) - Ulong (unsigned long) The selections available depend on the definition of the basic block.
GEI-100340 5.6 Changing the View of the Schematic Schematics can get larger than the window displaying it. Therefore the window shows only a small view on the entire schematic. This view can be changed in several ways: - the position of the view can be changed by the scroll bars and key combinations - the magnification ratio can be changed by menu items from the View menu and by key combinations. 5.6.
Wirdrive 5.7 Modifying Schematics A schematic is normally not entered one time but entered and changed several times. Modifying a schematic is done by performing two steps: - select one or more items to modify, - then perform the modification. Modifications can be done in several ways: - moving items, - duplicating items, - deleting items. 5.71 I Selecting Mocks and lines A block, junction, connection line, text or label is selected by clicking on it with the left mouse button.
GEL100340 5.7.4 Resizing items Basic blocks can be resized. This is done by the following steps: - Select the block. It will be surrounded by a red rectangle. - Move the mouse to one of the border lines or corners of the red rectangle. The cursor will change to a double arrow. - Hold down the left mouse key and move the mouse to the new size. - Release the left mouse key after the required size was achieved. If the block is getting too small to display texts they will not be displayed.
Wintllrive 5.8 Printing Schematics For documentation purposes Win+Drive schematics can be printed. Printing is started by the Print command from the File menu. A dialog appears that is used for setting the print options. There are two modes for printing schematics: - window print mode - page print mode The window print mode is used for draft printouts, while the page print mode delivers document ready prints. Both modes are started from the Print item of the File menu. Figure 5.8.
GEL100340 Figure 5.8.1.1: Page Print Mode Dialog 5.82 Printing in Page Mode For printing a scheme in page mode select Print from the File menu and then Page Mode from the tab riders of the dialog. The page mode dialog appears. Within this dialog you can change the following settings for the printing: - the margins of the printing at all four borders in inches. These margins will not be printed. They should be bigger than the printer margins.
WintDrive 5.8.3 Page Setup fur Printing For setting up the page for printing select Page setup from the File menu or Setup from the Print dialog. The Page Setup dialog will appear. Figure 5.8.3.1: Page Setup Dialog 1 (page setup) Figure 5.8.3.2: Page Setup Dialog 2 (stamp setup) Figure 5.8.3.
GEL100340 Within this dialog the following options can be set: the orientation and size of the paper, - the position and definition of the stamp (title block), - thegrid. There are checkmarks that determine if the stamp and grid are displayed and/or printed. Also the text inside the stamp can be shown or hidden. 58.4 Seffing Stamp Variables Stamps can include variables (for example for the name of the author, the company, the project etc.).
WintDrive 200 27 m Date : @date@ ,, 8 0 @Courier New 0 42 w Window : @winname@ ,, 8 0 @Courier New [Variable] Author=Mr. Black [Bitmap] ‘l:\wpd\smpl.ogo.bmp" 321 31 The file consists of sections which are introduced by the name of the section in square brackets. After the section heading one or more lines with information follow. All lines starting with //are comment lines and only for explanation.
GEI-100340 6. Connection to External Variables Programs generated using Win+Drive normally have connections to the environment outside. For example, set and measured quantities for control have to be read and output values have to passed to servos. For creating these connections between internal values of Win+Drive generated programs and external ones variables have to be defined and ports of blocks have to be connected to them.
WintDrive The storage class defines where the variable is declared and visible. The following values are available: - external variables are declared in the external program and can be used in the generated program. They get the attribute extem in the generated program. - global variables are declared in the generated program and can be used by the external program. They get no attribute in the generated program.
GEL100340 - the groups are defined in the target.ini files. They are used to put the index of the logical variable into a predefined range of the total variable (that normally is an array). “*” marks the default group that has no index checking. - the value is provided for setting an initial value. This value is used for initialization of the variable within the generated program. - a comment can be used to describe the logical.
Wintilrive 7. W o r k i n g w i t h Hierachy a n d C o m p o u n d B l o c k s Complex projects get soon so complex that it is not possible or useful to have all blocks in one schematic. For splitting a project into several schematics compound blocks are provided. Compound blocks contain basic blocks and other compound blocks. Compound blocks are inserted into schematics similar to basic blocks.
GEL100340 Z 1.3 R e n a m i n g a C o m p o u n d B l o c k The name of compound blocks can be changed by selecting item Rename from the Compound menu. A dialog appears that lists all compound blocks of the project. Selecting one allows typing a new name in the upper text box. This dialog can be used to change the names of all available compound blocks without leaving thedialog. Figure 7.1.3.1: Rename Compound Dialog If the name of a compound block is changed all instances get this new name.
WintDrive z7.3 Updating and Closing a Compound Block As long as a compound block is edited its instances in other schematics are not updated. To reflect all editing changes to these instances the compound block must be saved. This is done by the Update Instances item of the Compound menu. Windows displaying compound blocks are closed by the Close item of the Compound menu. If the compound block was changed and not saved a message box appears asking if it should be saved.
GEI-100340 7.6 Using Cbmpound BIocks Using compound blocks in schematics is equivalent to using basic blocks. Placing is done from the Insert menu or by Drag&Drop operations as described in paragraph 5.1.1. All available compound blocks are treated as a group of blocks. In the Insert menu the bottom item Compound opens a submenu with all available compound blocks.
Win+Drive 7.7.2 Import of Compound Blocks The import ofa compound block into a project is started by choosing Import Compound from the File menu. First the standard windows dialog for entering the filename will anuear. After selection of the file, the import process wilt start. First it is checked if groups, logical variables, variables and compound blocks (as part of the compound block to be imported) with the same name are used within the compound to be imported and the existing project.
GEL100340 For each compound block within the list the import action can be chosen. Selecting Accept and Replace will replace an existing block with the one being imported. Not Accept will not import the selected compound block and keep the already existing one. After finishing the editing of logicals and variables the block can be imported by pressing Import All. Now it is available for editing and insertion within the project. Abort All stops the import process.
Win+Drive 8. Generating Programs After the schematics of a program have been created they should be converted to programs that can be executed either on the PC or on the target system. The total code generation is split into two parts: - generating the C program from the schematics - compiling the C program to binaries. Generating the Program from the Schematic To generate the C program from the schematic select Generate C-Code from the Tools menu. This will start the code generation.
GEI-100340 Figure 8.2.2: Changing the execution order A block that is connected from its block output to the block input of another by this execution order connection line will always be executed before. Within the example shown this is done by putting this block into the execution chain before. 8.3 Compiling the Program After the code is generated without errors it can be compiled. Selecting the item Compile + Link from the Tools menu will start this process.
Wintllrive 9. Simulating Programs on the PC Win+Drive includes a simulation environment for the code that was generated for the PC simulation. The generated program is put into a DLL that is called from Win+Drive. To display output data of the simulation, probes can be set. The values of these probes can be displayed graphically in monitor windows (looking like oscilloscopes) and in a tabular form in trace windows.
GEI-100340 Figure 9.1.2.1: Set Debug Window Dialog Using radio buttons it can be selected if the probe shall be displayed in a monitor or trace window. The two lists at the bottom of the dialog are used to select the windows in which the probe will be displayed. Select the appropriate windows from the right list and move them by the left arrow button to the left list. A probe can be displayed in several windows. OK ends the probe setting while Cancel leaves everything unchanged. 9.
WintDrive 9.3. I Monitor Configuration Dialog This dialog is used for setting the display configuration of the monitor window: - the Y range can be set automatically or manually by entering the minimum and maximum values, - X and Y axis can be displayed or hidden, - Cross lines at the actual position of the mouse pointer together with a display of the x and y values can be displayed, - the x axis range can be set by a scrollbar. OK will apply these changes while Cancel leaves everything unchanged. 9.3.
GEL100340 9.5 Running fhe Model The simulation of the model is controlled by items from the Debug menu. - Go restarts the simulation and sets the variables to its initial values. - Step simulates the model once (one loop) - Continue simulates the model a number of loops that is setup by the Change run steps dialog - Stop terminates the simulation and returns to the edit mode of the schematic. -if the model has crashed Unload DLL can be used to remove it from memory.
WintDrive 10. C h a n g i n g S e t t i n g s of Win+Drive The configuration of the actual project and Wm+Drive can be changed by dialogs that are opened from the Options menu. IO. I Scheme Settings The scheme settings dialog is opened by selecting Scheme Settings from the Options menu. Figure 10.1.1: Set Scheme Dialog The two lists include all schematics of the project. Each schematic will be either in the list of compound blocks (left list) or of schemes (right list).
GEI-100340 10.2 General Settings Within this dialog the following settings can be done: showing or hiding the block toolbar (see paragraph 10.1) showing or hiding the quick info or quick value text boxes (see paragraph 10.
WintDrive 10.4 Setting up External Tools Table 10.4.1 lists the tool functions integrated into Win+Drive. Note that these tools may require the installation of programs and/or compiler(s) not supplied with Win+Drive. The Tools menu can be extended. This is useful for running other programs without leaving Win+Drive. The Tools item of the Options menu will open the tools dialog. Figure 10.4.1: Tools Dialog This dialog can be used for adding and deleting items of the Tools menu.

Witdrive Appendix A A. I Block library for DGFC The following Help Topics are available: Introduction Block Blocks in alphabetical order Note: This Appendix was current at time of printing. For the latest information, always refer to the on-line help. A.2 Introduction Win+Drive is a graphic editor that permits the development of schemes for any type of target that can be programmed in C language. A specific library of basic blocks can exist for any target. This manual presents the blocks for DGFC. A .
GEI-100340 Group It is used to group the different types of blocks in an homogeneous way, for instance arithmetical, logical etc. This grouping facilitates the search of blocks when compiling a scheme. ln the present version the defined groups are the following: I/O Mathematic Logical Timer Delay Function Control Arithmetic Variable Generator //O Group This group is composed of blocks that permit the control of I/O devices of the target.
WintDrive Logical Group This group contains all those blocks performing logical operations. Only integer data (id) can be treated by these blocks. There are two operator sub-groups: Control of data as a unique logical variable (logic), that means: TRUE if equal to zero if different from zero FALSE Control of data as a group of 16 logical variables, one for each bit that forms the data itself (bitwise).
GEL100340 Function Group This group contains special functions: Operator Diameter and thickness observer Speed observer Function name diamobs speedobs icon diamobs speedobs Vii015 Operator UP/DOWN counter Block for int data name icon icnt cnt Block for float data name icon fcnt cnt wQ316 Control Group This group contains all those blocks performing operations that will condition the execution of a scheme.
WintDrive Arithmetic Group This group contains all those blocks performing arithmetical operations. There are two operator sub-groups: Controls integer data (id) Controls floating point data (float) l l Variahh G r o u p This group is composed of blocks that permit the handling of variables and the conversion of types of data. Operator Generator Group This group is composed of blocks that permit the generation of wave-forms.
GEL100340 Input port Represents the element from which the block receives information in the scheme A block may have only one Input port, multiple Input ports or no Input ports. An Input port can be connected to the following elements: AVariable AConstant The Output port of another block through a connecting line The Input port of a Compound through a connecting line In any of the above mentioned cases, the connection can be performed only if the type of the elements comply with each other.

Wint Drive and Description This block carries out a bit wise “and” operation of the integer data read by input ports a and b. It shows the result of the operation in output port o.
GEI-100340 cfix il *l i2 fix B 42 co3 trim r [411 Description It performs a master DeviceNet communication (LocalBus). This block gets the input words (il, i2 and i3) and sends them to the appropriate slave, retrieves the words received from the slave and writes them to output words (01,02 and 03). It also manages the timeout signaling(to r output) when the communication does not occur for 1 cycle or for tmo cycles.

It is used to estimate rewinder or unwinder diameter with or without dancer. GearRt [>l] is gear-box ratio of winder.
WintDrive Control 0 1 otherwise 1 Description Functionalities are all enabled: diameter and thickness are estimated from line speed (LineSpd) and winder motor speed (WMotSpd) Diameter and thickness estimation are disabled, but diameter is updated according to actual thickness. This is used during speed match and when torret is rotating. In this case material path is changing so diameter estimation has to be disabled, however , diameter is increasing (or decreasing if unwind) of actual thickness.
GEI-100340 With two digital encoders with a resolution of 1000 counts/rev each and a sample time of 10 msec, WMotThrl and WMotThr2 should be larger than 10 rpm and 100 rpm respectively. Minimum diameter (MinDiam), maximum diameter (MaxDiam), maximum thickness (MaxThick) inputs are provided to limit possible error estimations. Zero is minimum thickness. User can initialize diameter and thickness using Initialize input.
