4 COSIMIR Professional Like COSIMIR Educational, this software enables one to write control programs for the Mitsubishi robot and the computer testing programs. The difference between COSIMIR Professional and COSIMIR Educational is that in addition to programming Mitsubishi robots program, the robots KUKA, ABB, Fanuc and other firms, the former allows one to download the control program into the robot control device and control the real robot via computer. COSIMIR Professinoal allows one to create new applications for the robot by using some robot simultaneously. Devices/details, used to build models for 3D model applications of a new robot must not necessarily be those of COSIMIR Professional, but models created in other CAD programs can be used.
Modeling Extensions for COSIMIR Professional support the composition of robot-based workcells. Efficient modeling is provided by using component libraries, machinery contained, robots, tools, conveyor, belts, part feeders, etc. Free 3D modeling and import from CAD systems are also possible. The number of important filters has considerably increased.
4.1 Start-up Starting the program COSIMIR Professional consists of the following steps: START Programs COSIMIR Professional COSIMIR Professional (Fig. 4.1). →

4.2 Window RCI Explorer RCI Explorer gives a review of the status of a real robot. The RCI explorer enables you to upand download programs, simply by drag-and-drop. You can start programs in any slot you want and keep track of the actual state of your robot parameters, fault messages, system variables, etc.
The window RCI Explorer (Fig. 4.4) contains two main folders. The first folder is the robot folder the designation of which is the name of the robot (in Fig. 4.4 it is RV-2AJ ). This folder opens access to information in a robot control device. The second folder is the Workplace which contains information about the COSIMIR Professional project.
Fig. 4.4. RCI Explorer window
From the robot folder you can find information about data communication between the robot and the computer, information about robot type, lists of programs in the control device and positions, information about program slots, system variable data, information about the status and parameters and, fault messages of the robot. The Workplace folder finds the robot control program from COSIMIR Professional, the robot position list and other data. When the RCI Explorer window is closed, choose the command RCI Explorer…from Execute menu and the window is opening.
4.3 Data communication between the computer and the robot control device To create data communication the COM port of the computer must be connected to the RS-232 port of the robot control device. The switch MODE of the control device must be on position AUTO (Ext.). As it follows, the software COSIMIR Professional must be operating in the computer where the project of the robot control program is open. The type of the virtual robot is the same as the type of the real robot. When the types of the robots are different, choose another application or create a new. To create data communication between the computer and the robot control device, choose the command Init Connection from COSIMIR Professional menu Execute. When data communication is created, the RCI Explorer shows different data about the real robot. For example, by clicking on Programs folder which is located in RV-2AJ folder (in some other 47
project, the designation of this folder may be different) the designations of all control programs are shown (Fig. 4.5). When clicking on the Programs folder the first time, for renewing the contents of the folder occurs. During the renewing all t he programs are searched and information about these programs is given in the folder Programs. Second clicking on the Programs folder does not renew the contents of the folder, as the user does not require this.

Data communication between the computer and the robot is possible via Ethernet. For that purpose the robot control device must have the Ethernet card, make sure you know IP aadress of the card and the computer and control device must be connected to the same net. Before creation of data communication it is necessary to make adjustment of the Ethernet connection on the TCP/IP panel in the Communication Port window.

During downloading the control program and the position list into the robot control device, the messages may appear. The reasons are: 50
1. A designation of the downloading program is confirmed with the designation of the program in the robot control device. 2. An empty program or the position list is downloaded into the control device. 3. Deleting the old program in the control device has failed. In the case of the first fault, the program and the position list must be renamed or overwritten and in the case of the second, fault downloading must be aborted. When the third fault appears, then the program in the control device must be deleted manually. For that purpose choose the designation of the program which you want to delete in RCI Explorer window from RV-2AJ Programs folder by the help of the right button of the mouse. Then choose Delete (Fig. 4.12) from drop-down menu.

4.6 Program testing on the real robot It is very important to test the control program before commissioning it on the real robot to find all programming errors. During the control program testing make sure that no one has been near the robot (robot operating area). It must be ensured that the programmed coordinates of the robot position are out of the real robot operating area. It means that the robot may move to a wrong position and injure the personnel. To start program testing, choose the designation of the program in RCI Explorer window from RV-2AJ Programs folder by the help of the right button of the mouse. Choose the command →

On program testing always determine the row wherefrom the program testing starts or continues. For that purpose choose the required program row in the Debugger window and click on the Set active line icon. The green arrow marks the active row. There are different methods for program testing. The first method is program testing by a row. By clicking on Single step icon the command on the active row is executed and then the next row is changing active. To execute the command on the new active row, click on Single step icon once again. By using Single step backward icon the command on the active row is executed but after execution this command the previous row will turn active. In another program testing method, the stop-points which are stopping the test are used. These stop-points are determined by the help of the double click on the row where t he program must be stopped. To start the test, click on the Start breakpoint debugging icon where the execution of every program row is shown. When the testing reaches the row where the stop-points are located, 53
testing is aborted. It is possible to delete superfluous stop-points by the help of double click on the row where stop-points are. To delete all stop-points Clear all breakpoints icon is established. The third program testing method is the whole program testing without stops. For that purpose click on the Start icon. Click on the Stop icon to stop program testing. It makes it possible to stop the program test started by using Start breakpoint debugging icon until the program test does not arrive to the row signed with stop-points. To follow the program test, the text near the button ON of Online section must be grey. When the text is not grey, click on this text to look at the program execution. By clicking on the Close icon the Debugger window is closing. It is reasonable to close the window at the end of program testing.
4.7 Start-up and stopping the program in the robot control device To start the robot control program in the robot control device choose the designation of the Programs folder by the help of the right program in the RCI Explorer window from RV-2AJ button of the mouse. You may choose two starting commands from drop-down menu (Fig. 4.17). The first command is Start (CYC), which starts the program and executes it at once. The second command is Start (REP), which starts the program and executes it from the beginning to the end until the program is stopped by the user. →
