The Element Window

Program elements are icons that, when selected, access instruction sets in the ROBO Pro software to perform the operations identified by the icons. They are located on the left hand side of the

screen

The Flow Chart

When Program Elements are placed on the screen and connected, a Flow Chart is created.

This Flow Chart is the program that runs the instruction sets

Programming

The Motor Outputs can be set to run an electromagnet, lamp, or motor.

Motor Output

Motor Outputs

Start & End

The Start and Stop Function Blocks begin and end a program.

The program to control two output devices might look like this…

Start Program

M1 Output On

M2 Output On

End Program

Outputs

The Time Delay is used to introduce a delay in a program.

Time Delay

A time step can be set for seconds, minutes or hours

Digital InputsInputs

The “Input” function block queries the state of a digital input I1-I8 on the interface. They many be a Pushbutton switch, Photo-transistor, or a Reed contact.

A digital input can only have one of two states, 0 or 1.

Examples: Pushbutton switch Pushed or not pushedPhoto-transistor Light or DarkReed Contact Switched or not switched

Digital Inputs

Phototransistor(light sensor)

Switch (pressure sensor)

Reed Contact(magnetic sensor)

The Digital Inputs can be set as a variety of switch mechanisms including Pushbutton Switch, Photo-transistor, or Reed Contact.

Digital Inputs

Digital Inputs connect to I1-I8 on the interface

Text

The Text tool is used to display

information on the program page.

Wait for Input

Waits for the input to change in a particular way

Wait for Input

Wait for Input is simpler and easier than using the Digital Input icon for some applications.

Counter Loop

With the Counter loop you can execute a specific part of the program several times.

Counter Loop

This counter loopallows a light toflash on for 2 seconds,then off for 2 seconds, 10 times before stoppingthe program.

Analog Branch

With the Analog Branch you can comparethe value of an analoginput with a fixednumber and, accordingto the result, branch tothe Yes (Y) or No (N)exit.

Set the condition and enterThe comparison value

Analog Branch

This Analog Branchuses a photocellsensor to determineif the reading (value of AX) is greater than 800. When it is, the light is turned off and the program ends.

Going Farther

There are times when more options are needed in a program.By selecting Level 4 more programming options become available in addition to the basic elements.

Variables

Variables are accessed from the element window.

Variables

Variables hold values to allow the program to make decisions.

The variable can be named anything.

Commands

Commands are used to change the value of variables.

Branch and Wait

Decisions are made on variables using commands from the Branch and Wait section.

Variables A Variable can be used to

count as in this example. The variable Dogs is increased by one each time through the loop until its value is greater than 3. The program then ends. The Variable blocks are named the same eliminating the direct connection.

Inputs and Outputs

Inputs and outputs are used to affect variables and to display their value.

Variables A variable can be

used to store a value. In this example the value of a CdS photocell is stored (input) as a variable and used to determine which way a motor will turn.

Operators

Operators allow us to combine or compare two variables using mathematics or logic

Panel Elements

Panel Elements are use to build a display or control board to interact with a Fischertechnik model.

DisplaysThere are times when the value should be displayed on the screen.

Setting up a display

Text Displays can be customized

Displays

Panel displays are used to assign the output device

Sub-ProgramsSubroutines are used to create pieces of a program that can be used many times in different places.

Subprogram utilizing the Entry and Exit commands

SubprogramsOnce saved the subprogram is ready to be used from the loaded programs.
