Tutorial 5 Robot Studio – IO Signals

1. IO Board and IO Signal Creation 1.1 I/O boards

• Robot generally has one or more I/O board(s).

• Each of the boards has several digital and/or analog channels that must be connect to logical signals before they can be used.

• A physical channel can be connected to several logical names, but can also have no logical connections.

I/O BOARD

OUT16

OUT2OUT1

Physical Channel

IN16

IN2IN1

feeder2

do16

gripper

do2

Logical Signal

feederdo1

1.2 Input and output signals • Robot can be equipped with a number of digital and analog user signals that can be read and changed

from within the program.

• The signal names are defined in the system parameters, and the signals can be read from the program by using these names.

• The value of a n analog signal of a group of digital signals is specified as a numeric value.

1.3 Teach pendant

1. Teach Pendant simulates the robot controller teach pendant, and let your work with the Virtual Controller exactly the same way as with the real Controller.

2. Teach Pendant starts accompanied by

• Control Panel, and

• Joystick windows

1.4 Create I/O signals with Teach Pendant 1. Set Control Panel in Manual Mode (<250)

2. Create I/O unit (board)

Misc. window System Parameters Add key in parameter information

3. Create I/O signals

Types menu User Signals Add Key in parameter information (DO or DI)

4. Restart Robot Studio to enable the newly created IO unit.

1.5 IO Simulator The IO Simulator displays the current state of digital input and output signals during program execution. It allows you to set and reset both digital inputs and outputs. This feature is useful for testing robot programs that may set outputs or wait on certain input states before continuing.

In Robot Station, click on Robot under Components directory in Object browser.

Mechanism menu IO Simulation…

The IO Simulator automatically configures itself with the IO boards and signals in use by the Virtual Controller. A yellow light indicates the input or output is on, while a black light indicates it is off. A panel is light gray if the input or output is defined, while a dark gray panel indicates it is undefined.

1.6 Event Table With the event table actions can be simulated when a specified event occurs. For instance, you can attach an object to a gripper when the gripper reaches the object, or when an I/O signal is set.

In Robot Station, Simulation menu Event Table…

2. Tutorials In this tutorial, you will learn how to

• Create an IO unit with Teach Pendant

• Define User Signals with Teach Pendant

• Use Event Table to attach, move, and detach objects

2.1 Prepare the station 1. Create a New Station.

2. Import Library…: (robot) Irb640_M98-M2000.rlb

3. Import Library…: (tool) \Library\Tools\Gripper_PBT.rlb, and attach it onto the robot.

4. Import Library…: (tool) two pallets: \Library\Equipment\Euro_pallet\euro_pallet.rlb. Reposition them to (500, 750, 0, 0, 0, 0) and (500, -1550, 0, 0, 0, 0) respectively.

5. Create Part: A box with length=1000, width=500, height=500.

6. Rename the part as Box.

7. Reposition the Box to (600, -1400, 145, 0, 0, 0)

8. Setup Controller by Create copy from IRB640_M2000, and Rename the copy to IRB640_tut5_*(your ID).

9. Start Controller.

10. Save the station as Event_tut5_*(your ID) to your folder.

2.2 Create target and path 1. Create target

Target1:1 Rename to Pick_1:1 (1100, -1150, 1000, 0, 180, 0)

Target2:1 Rename to Pick_2:1 (1100, -1150, 645, 0, 180, 0)

Target3:1 Rename to Midway:1 (2000, 0, 1300, 0, 180, 0)

Target4:1 Rename to Drop_1:1 (1100, 1150, 1000, 0, 180, 0)

Target5:1 Rename to Drop_2:1 (1100, 1150, 645, 0, 180, 0)

2. Create path (Path1): drag the targets to Path1, and the sequence will be:

Pick_1:1 Pick_2:1 Pick_1:1 Midway:1 Drop_1:1 Drop_2:1 Drop_1:1

3. Change the Motion Type of ‘Pick_2:1’, and the following ‘Pick_1:1’, ‘Drop_2:1’ and the following ‘Drop_1:1’ to ‘MoveL’.

4. In Program Browser, under Program Modules, Insert module, and the Insert main procedure under Module1.

5. In Object Browser, Right-click Path1, and Sync to VirtualController.

6. In Program Browser, drag Path1 and drop it to main.

7. In Object Browser, Right-click Path1, and Move Along Path. Look at the movement of the robot.

8. Make the robot Move to Home, by holding ‘Ctrl’ key and press on ‘Home’ key on the Key Board.
