2.1

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. Now
the continuous operation is replaced by the cyclic execution of a control program. Programs consist of a

sequence of operations. For describing programs, typically text files containing program code in assembler or
high-level languages like “C” are used. This kind of representation is often not appropriate for the description
of control tasks.

Win+Drive is a graphical program generator for the Windows

control tasks. Building control programs is as easy as drawing block diagrams. Basic pieces of code are
placed on a schematic and are connected. Parts of the whole control structure can be put into compound
blocks that are inserted into schematics once or several times. From this graphical representation code is
generated that can be compiled and executed on the PC for simulation and on the target system.

operating system especially designed for

2.2 Introducing the Tools

2.2.1 The Schematic Editor

The schematic editor is the most important interactive tool of Win+Drive. It is used to create and edit the

schematics. These contain the basic blocks which represent library elements with pieces of code within them
and compound blocks which are schematics by themselves. The blocks are connected by connection lines to
make the output value of the calculation of one block the input value of another one. Texts and labels can be
inserted into the schematic as comments.

There are numerous commands to modify schematics. Schematics can be printed for documentation purposes.

22.2

While the schematic editor is an interactive tool with a lot of user commands the code generation is a batch
process that is started by only a few commands. It generates C code from the schematics and compiles it to

executable binaries. The PC itself or the target system can be selected as the platform for the code generation.

The Code Generation

2.2.3 The Simulator

The generated code can be executed on the PC. For this purpose Win+Drive includes a simulation and prob­ing shell. Probes can be set on ports of blocks to be displayed during simulation graphically or in tabular lists.
The simulation can be run for one or several cycles.

2.2.4 The library Editor

For creating and modifying the basic blocks which build the library for Win+Drive applications some tools
for creating and modifying the library are provided. This includes an editor for the graphic symbols of the

blocks and a library tool for the administration of the source code of the basic blocks.

2.3 The Development Process

GEI-100340

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.

Simulate the generated code on the PC for debugging. If errors are found go back to step 2. Change the
schematic, generate and compile once more and simulate again.

5.

Generate code for the target system and compile it.

6.

Run the compiled code on the target system.

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. If the size of the child windows is larger than the client space of the main
window scroll bars appear which can be used to move the actual visible portion of the total client area that is

used by all child windows.

The Win+Drive main window can be

minimized, resized and maximized by the standard methods of Win-

dows. In most cases it will be run in maximized mode.

Creating

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. This software
function evaluates input values which are represented by input ports and calculates output values which are
represented by output ports. If the input port of a block is connected to the output port of another then this
block will read the results of this preceding block.

There are two different types of blocks:

basic blocks

compound blocks.

Basic blocks are the atomic building parts and always represent software code. Compound blocks are repre-

sentations of schematics and are used for dividing the total project into several schematics within a hierachy.

Compound blocks will be described in detail in Chapter 7.
Basic blocks are organized in groups. Since there can be a large number of different basic blocks its easier to

select them if there is this kind of organization and ordering. Groups are normally organized in a way that
basic blocks with similar functions are grouped together (for example arithmetic blocks, logical blocks,
function generators).

For placing blocks onto the schematic two different methods are implemented:

-

placing by drag&drop from the block toolbar

-

and selecting from the insert menu.

To place a block from the Block Toolbar perform the following actions:

-

first select the appropriate group by clicking an icon of the left side of the Block Toolbar. Now the right

half of this

-

select a block from the toolbar by moving the mouse onto its icon and pressing the left mouse button. The

mouse cursor will change to a symbol representing a block

-

hold down the left mouse button and

move

the mouse to the place within the schematic the block should

be placed (Drag action)

-

At this point release the mouse button. The block will be placed at this point (Drop action).

If the mouse is positioned on a point where the block cannot be placed (outside the client area of a schematics
window) the mouse cnrsor changes to a symbol showing that no drop action is possible.

5.2 Connecting

S&ware

Blocks

Connection lines between blocks are the graphical representation that one block is evaluating the results of
another one for its own calculation. Therefore connections are always done between the output port of a block
and the input of the next one. One output can be connected to several inputs.

For drawing a connection perform the following actions:

-

place the mouse onto the port of one block

-

press together the

shall be connected. During

this movement a direct line is drawn from the starting point to the actual mouse position

-

after the mouse pointer has arrived at the port that shall be connected release the left mouse button. Now a
rectangular connection line that doesn’t overlay blocks is drawn between the two ports.

If an output shall be connected to several inputs, first draw the connection from this output to one input. Then
start a new connection from a point of this existing connection line to the next input. The starting point will
get the junction of the two connection lines.

Connection lines can also be created between blocks (instead of the ports of blocks). This is used for changing
the execution order (see chapter 8). Creating these lines is done by pressing the left mouse button within the
block center of the block that should be executed first. After holding down the mouse button and moving the
mouse to the block that has to be executed after the first one, the button is released. Now a connection line
between the two blocks is drawn. A virtual output and virtual input are created for this purpose.

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

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.

5.4.1 Opening the Ports Editor Dialog

The ports dialog for a block is opened by double-clicking a block or by selecting a block, pressing the right
mouse button to open the context sensitive menu and selecting

Ports..

from this menu. The ports dialog is

used for changing properties of all ports of one block

Figure

5.4.1.1: Ports

Editor Dialog

Within the Ports Editor dialog there are two lists that include all input and output ports. After selecting one of
the ports its properties can be changed by the control elements in the middle of the dialog window. The port
that is selected immediately after opening this dialog is determined by the mouse position at the time the

block was double-clicked or the right mouse button was pressed. Thus the user can determine the initial

selection by double-clicking a port of the block.

5.42 Setting the

Putt

Connection

For each port the type of connection can be changed by selecting an item of the drop down list box. The
following selections are available:

-

None: the port has no connections. Output ports can be left open (if the result is not used). Input ports
have always to be connected to something.

-

Variable: a variable is used for connecting the schematic to the embedding program of the target system.
Variables are described in detail in Chapter 6.

-

Tag: a tag is a connection that is done by setting the same tag on different ports within one schematic.
Tags are useful for connections to many ports. All ports that share the same tag string are connected.

-

Connection line: this choice is selected if a connection line was drawn. Setting the combo box to this
value will cause an error after closing the dialog.

-

Constant: the input of a block will be set to a constant value. Setting an output port to a constant will

cause an error message after closing this dialog.

20

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. Especially basic blocks for arithmetic
operations provide a wide choice of data types. During code generation it is checked if the selected data types
fit together.

5.5

Editing Block Parameters

Some basic blocks not only have ports but also parameters to determine their behavior. These parameters can
be considered as internal constants of the block that can be set to fixed values by the user while creating the
schematic. The parameters are changed by opening the parameter dialog. First a block has to be selected, then
the context-sensitive menu has to be opened by pressing the right mouse button and finally the

Parameter..

item has to be selected from this menu.

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.

5.6.1

Positioning the View

The actual position of the view is changed primarily by using the scrollbars on the left and lower side of the
window. There are some key combinations that have similar effects:

-

pressing the cursor keys moves the view into the corresponding direction

-

pressing the cursor keys together with the

CTRL

key moves the view by larger portions in the correspond-

ing direction

-

pressing

-

pressing the

PAGE-UP

HOME

or

PAGE-DOWN

has the same effect as pressing

CTRL+UP

or

cm+~om

key moves the view to the upper left comer of the schematic.

All these key operations can be used to move the view freely over the whole schematic.

5.6.2

Changing the Zoom factor

To be able to see more details or larger portions of the schematic within one window the magnification factor

(also called the zoom factor) can be changed by using menu items from the View menu. Most of these menu
items are also available by key combinations. The following operations are provided:

-

zooming into the schematic (increasing the magnification)

-

zooming out of the schematic (decreasing the magnification)

-

zooming to original size

-

zooming to a magnification that the whole schematic fits onto the window

(ALT+~)

(ALT++)

(ALT+-)

(AL.T+~)

If the zoom factor has a small value texts are no longer displayed. They are only visible if the magnification is
high enough.

5.6.3 Displaying additional Information on the Window

Within the view menu there are items that can be checked to make additional information available:

-

if the

Execution Order

item is checked the order of execution is displayed for each block after code

generation has been executed.

-

if

the

Quick Info

item is checked the name of each port and block is displayed within a small info box
above the cursor position. This box is displayed immediately after the cursor moves over the port of
block.

-

if the Quick value

item is checked the actual value of a port is displayed during simulation after the

mouse moves over it.

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. The

selected item will be surrounded by a red rectangle.

To select several blocks or junction press the

SHIET

key and select the next item.

It is also possible to select all blocks and junctions within one rectangular area:

-

Press the left mouse button outside an item,

-

Move the mouse with the left mouse button pressed down. A rectangular box is shown.

-

Release the mouse button. Now all blocks and junctions within this area will be selected.

It is not possible to select more than one connection line segment or more than one text or label at a time.
Multiple selections are only possible with blocks, junctions, inputs and outputs.

If all items within one schematic shall be selected the menu item
Deselection is done by pressing the

ESC

key. All selections disappear

Select All

from the

Edit

menu can be used.

5.7.2

Moving selected items

Selected items can be moved by the following actions:

-

Move the mouse into one of the selected areas (red surrounded).

-

Hold down the left mouse button.

-

Move the mouse with the button held down to the new position. The selected items will be moved to­gether with the mouse.

-

Release the left mouse button at the fmal position.

If blocks are moved the connections are modified in a way that its relative position to the blocks are kept.
Also labels are moved together with blocks so that their relative position to the blocks are kept. If segments of
connections lines are moved the junctions are adapted to the new position.

5.713 Copying and Moving via the Clipboard

Portions of a schematic can be moved or copied within one schematic or between different schematics within
one project by using the clipboard

If blocks are cut from the schematic all connection lines to not-selected blocks are deleted. The connection
lines between the selected blocks are kept in the clipboard. Pasting after cutting within the same schematic
doesn’t restore the position and connections of the selected blocks.

If blocks are copied to the clipboard all connections between these blocks are kept and all connections to not
selected blocks are not put into the clipboard.

Pasting from the clipboard is always done to a fixed position in the middle of the active window. After pasting
the items they have to be moved to their final position.

23

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. Resizing is always done in grid
units. There is a minimum size that is defined by the number of ports.

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. The connections are managed

not directly by the variables but by aliases called logicals.

6.1 Variables and

Logicals

There are two kinds of objects for connecting internal ports to the outside world:

-

variables are used in the generated program and provide the names that are used by external programs,

-

logicals are used in the schematics and are connected to ports. They are mapped to variables.

Variables are initially defined by the file

Target.ini that is read during startup of Win+Drive. During the

execution they can be edited by the variables dialog.

Figure 6.2.1: Variable Editor Dialog

The dialog lists all available variables in a multi column list:

-

Nbr is used for numbering the list,

-

Variable name contains the name. If a variable consists of an array the size is appended after the name in

square brackets (i.e.

-

Data type shows the type.

-

Storage class shows where the variable is defined and available.

FVAR[lUi.I]

is an array of 100 elements).

Pressing the New button will insert a new line into the list with a new variable. Its initial name and attributes
can be edited.

Delete

removes a variable from the list. Variables that are described as read-only in the file

target.ini cannot

be deleted from the list.
To edit a variable the corresponding line must be selected by clicking with the mouse. The name can directly

be edited in the list while the type and storage class are changed by selecting other entries in the appropriate

lists.
The data types are the standard C data types and correspond to the data types of the ports described in para-

graph 54.3.

30

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.

-

static variables are declared in the generated program and cannot be accessed by the external program.
They get the attribute static.

-

local variables are declared in the generated program, but within the blocks that use these variables (not in
the global scope as compared to static variables).

All changes to the variables are saved by pressing OK. They are stored in the project file. To change the
initial settings the file

target&i

must be edited.

6.3

The Logicals Dialog

While variable names are included into the generated program and are used by external programs, the logicals

are used within Win+Drive to connect ports to these variables. The connection is done by the port dialog that

is described in paragraph 5.4.1. Within this dialog a logical can be selected if the connection type is set to

variable.
The logicals available and their mapping to variables is edited by the

Logicals

item from the

Edit

menu.

Choosing this item will open the Logical Variable Editor dialog.

Figure 6.3.1: Logical Variable Editor Dialog

Within this dialog a list is used for all logicals available. The different columns display the attributes of each
logical. At the bottom of the dialog there are some lists that can be used to change a value of a column of the
selected logical. The columns are used for these attributes:

-

the Nbr is a used for numbering

-

Logical shows the name of the logical,

-

Variable shows the name of the corresponding variable the logical is mapped to. This can be an array. In
this case an index must be entered or the Fixed field can be set to “No”. Toggling between “Yes” and
“No” is done by double-clicking the Fixed field.

-

the data type and storage type of the variable are shown. For variables that are not read-only these at­tributes can be changed within this list.

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.

New entries are inserted by the New button, while selected items are deleted by the Delete button.
If an entry

Working with

Hierachy

and Compound Blocks

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.
The inputs and outputs of compound blocks represent their connection to the upper level of hierarchy and
build the ports of inserted compound blocks.

The port dialog is similar to the one for basic blocks (see paragraph 54.1) except that now the names of the
ports can be changed.

Renaming the port of a compound block results in deleting the connection lines to this port at every instance
of this compound block.

The input and output port symbols can be resized. This is done by the following steps:

-

Select the port The port 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 is achieved.

If the port is getting too small to display the name this will not be displayed.

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. In the block selection toolbar there is also one icon in the left part (“CB”) that will display
all compound blocks in the right part of the toolbar.

Double-clicking the instance of a compound block will create a new window where the block can be edited.
This is an easy and fast way to change the contents of a compound block from its instance.

1.7

Export and lmporf of Compound Blocks

Compound blocks often describe structures that are not only useful for one project, but can be used also in
other projects. Compound blocks used within one project are stored in the project file with extension.

WDR.

To move them to other projects they can be exported from one project and imported into another. Doing this
the contents of the compound block will be stored in a file with extension.

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.

8.1

To generate the C program from the schematic select

Generating the Program from the Schematic

Generate C-Code

from the

Tools

menu. This will start

the code generation. Output messages and error messages are placed into the output window.
If errors occured there will be error messages in the output window. Double-clicking these lines will open the

schematic where this error is located and will put the cursor position at the appropriate block or port. The item
that caused the error will be blinking. This can be used to go very quickly to the source of the error.

8.2

Execution

Order

After generating the code the execution order is displayed if the appropriate option was selected within the

View

menu. The order is shown in the left upper corner of each basic block and consists of two numbers. The
first gives the number of the chain of basic blocks in the order they are calculated. Win+Drive always places
blocks whose output values are only used by one other block or variables into a chain. The second number is
the order within this chain. This order is on a stack basis: a block with a lower number will call the block with

the number above. This block will thus be calculated before. Therefor the order of the second number is from

back to front within one chain.

. .

Figure 8.2.1: Execution order

To change the execution order, basic blocks can be connected. These connnections are created similar to the
connections of ports of blocks, but now the body of the blocks is selected. A connection line will appear that
extends from one block to another.

A block that is connected from its block output to the block input of another by this execution order connec-

tion line will always be executed before. Within the example shown this is done by putting this block into the

execution chain before.

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.

To run a simulation the following steps must be performed:

-

the project must be successfully generated and compiled for the PC simulation.

-

probes must be set for all variables that shall be displayed in monitor or trace windows.

-

the monitor and trace windows have to be defined.

-

the simulation will be started for one or more steps. After each simulation step the actual values of the
ports can be examined using the quick value function of the schematics.

-

now the simulation output can be watched using the monitor and trace windows.

As long as the simulation is running the schematics cannot be changed. The simulation has to be stopped
before making any changes.

91

Setting Prubes

Probes are set on ports of blocks. Only the values of ports where probes are set are traced during the simula­tion, For setting probes two methods can be used:

Diamobs is a algorithm with two time constants:

Taul [set] and Tau2

[set]. These inputs determine time that

observer takes to estimate diameter and thickness.

The simplest case is when user needs to estimate only diameter: Tau2 must be set to

le9 [set]. Taul [set]

is

diameter estimation time constant. It represents the same concept of time constant in electronic analog circuits

and it is equivalent to the product of Resitance and Capacitance. It is the time that estimated value takes to

reach 63% of its steady state value. After four times time constant reaches steady state value (98%).
More complex case is when user needs to estimate both variables: diameter and thickness. This is the case

when material is very thick.

If for example user wants to estimate diameter with a time constant of 2 [set] and thickness with a time
constant of 10

and

Tau2 [set]

to 10 [set]

(Tau2 [set]

to 2 [set] and

and Tau2 is the time constant of diameter estimation while the

largest value is the time constant of thickness estimation.
Diamobs can estimate diameter and thickness with accuracy depending on winder motor speed

(WMotSpd):

the higer winder motor speed, the more accuracy estimation will be. When winder motor speed is close to
zero, estimations have to stop. For this purpose two winder motor speed thresholds are provided
and
