Setup of Robot Programming in MachineLogic for Universal Robots e-Series

Overview

Vention now offers Universal Robot Programming directly in MachineLogic alongside Vention actuators directly in Vention’s pendant. With a few extra steps, you can deploy your robot enabled program in minutes.

This document describes the steps necessary to get up and running with Robot Programming in MachineLogic for Universal Robots e-Series, which enables the seamless integration of a UR six-axis robot arm alongside Vention motion components, all while staying in Vention’s no-code environment. Applications like range extenders, cobot palletizers and other custom robot cells, are now possible within the Vention platform.

1. Connect your system

In order to program your UR e-Series Robot in MachineLogic, a Vention MachineMotion 2 Pendant V2 (CE-TP-004-0001__2) and a Vention Robot Safety Module (CE-SA-009-0000) is required, in addition to a MachineMotion v2 (CE-CL-010-0004 or CE-CL-010-0001) running firmware version v2.7.0 or later.

1.1 Physically connecting the UR and MachineMotion controllers using the Robot Safety Module

This section discusses connecting a MachineMotion V2 to a Universal Robot controller by way of the Robot Safety Module, in order to program the robot through MachineLogic. The Robot Safety Module acts a 3-port Ethernet switch to enable seamless communication between the MachineMotion, the pendant, and the robot controller (see Figure 1). For more information, refer to the Robot Safety Module User Manual.

The steps below outline the required connections seen in Figure 1 and Figure 2.

1. Connect the Robot Safety Module to the MachineMotion 2 Pendant (CE-TP-004-0001) or any other Vention safety module using the MachineMotion 2 Safety Extension Cable – 5m (CE-CA-102-5001) through the SAFETY IN connector. In case the MachineMotion 2 Pendant or any other Vention safety module are used, the included yellow jumper must be inserted.
2. Connect the Robot Safety Module to the MachineMotion V2 Controller using MachineMotion 2 Safety Extension Cable – 5m (CE-CA-102-5001) through the SAFETY OUT connector.
3. Connect the Robot Safety Module to the robot controller using the Robot Safety Module “TO ROBOT” Cable (CE-SA-111-0001) through the TO ROBOT connector. The other ends of the cable, connect as follows:
   • Robot Safety Input Channel 1 Contact 1 (white wire) connects to the first contact of the emergency stop input in the robot controller
   • Robot Safety Input Channel 1 Contact 2 (green wire) connects to the second contact of the emergency stop input in the robot controller
   • Robot Safety Input Channel 2 Contact 1 (pink wire) connects to the third contact of the emergency stop input in the robot controller
   • Robot Safety Input Channel 2 Contact 2 (yellow wire) connects to the fourth contact of the emergency stop input in the robot controller
   • Robot Input Reset Contact 1 (black wire) connects to 24V output in the robot controller
   • Robot Input Reset Contact 2 (grey wire) connects to a configurable input in the robot controller. This input should be configured as “Reset” in the robot’s interface
   • The RJ45 connector connects to the Ethernet port in the robot controller
4. Connect the Robot Safety Module to the robot controller using the Robot Safety Module “FROM ROBOT” Cable (CE-SA-112-0001) through the FROM ROBOT connector. The other end of the cable, connect as follows:
   • Robot Safety Output 0V Contact 1 (brown wire) connects to a 0V output in the robot controller
   • Robot Safety Output 24V Contact 1 (black wire) connects to a configurable output in the robot controller. This output should be configured as Emergency Stop output in the robot’s interface.
   • Robot Safety Output 0V Contact 2 (blue wire) connects to another 0V output in the robot controller
   • Robot Safety Output 24V Contact 2 (white wire) connects to a configurable output in the robot controller. This output should be configured as Emergency Stop output in the robot’s interface.

NOTE: If your system has more than one controller set up in a Multi-Controller configuration, the safety chain which includes the Robot Safety Module and the Pendant must be connected to the parent controller.

1.2 Configuring up the UR controller’s Network

On the UR teach pendant home screen, select Menu > Settings > System > Network. Select Static Address as your network method & change the IP address to 192.168.5.3, Subnet mask to 255.255.255.0, and Default Gateway to 0.0.0.0 (see Figure 3a & 3b). Select Apply when done.

2. Pre-connection Setup on UR controller

2.1 Installation of the External Control URCap on the UR controller

Step 1: Insert the USB drive

Vention’s Robot Programming in MachineLogic for Universal Robots e-Series software is distributed on a USB flash drive and must be installed on the UR teach pendant before continuing onto working in the Vention pendant. To install the URCap, insert the USB drive into the UR teach pendant’s USB port.

Step 2: Add the External Control URCap to the UR environment

On the teach pendant home screen, select Menu > Settings (see Figure 4a).

Select System > URCaps, then click the + icon at the bottom of the screen to add a new URCap to the UR teach pendant (see Figure 4b).

Select the .urcap file and click Open to install the URCap extension (see Figure 4c).

Step 3: Restart the UR controller

When prompted to do so, restart the UR controller to complete the installation (see Figure 5).

2.2 Configuring the External Control URCap

Step 1: Navigate to URCaps Installation Page

On the teach pendant, select Installation > URCaps (see Figure 6).

Step 2: Set Host IP and Custom Port

Change the Host IP to 192.168.5.1 and the Custom Port to 50002 (see Figure 7). You may use any Host name desirable.

2.3 Enabling Remote Control

On the teach pendant home screen, select Menu > Settings (see Figure 8a).

Select System > Remote Control, then click the Enable (see Figure 8b).

2.4 Verify Tool Center Point (TCP) is Zeroed

The Tool Center Point, or TCP, defines the coordinate system found at the end of the tool mounted to the robot. For Robot Programming in MachineLogic, the TCP, wether an end-of-arm tool is mounted or not, is located directly at the robot’s flange, also known as position 0, 0, 0.

On the teach pendant, select Installation > General > TCP, and verify that all values associated to X, Y, and Z, as well as RX, RY, and RZ, are set to zero (0) (see Figure 9). If not, make the necessary changes.

2.5 Create and Run an External Control program

Step 1: Create a new program

On the navigation bar of the teach pendant, select New… > Programs (see Figure 10).

Step 2: Add the External URCap to the program

On the left-hand side navigation tree, select URCaps > External Control (see Figure 11). You should see Control by Host name** appear under the program tree view. Verify that the information found on the right-hand side (Host IP and Custom port) match what was set in section 2.2 - Step 2. The program can be saved for future use by selecting Save… > Save Program As….

Step 3: Change from Local to Remote Control

NOTE: This step is important and often forgotten. The robot controller must be in Remote Control mode for MachineLogic to properly connect.

At the right of the navigation bar of the teach pendant, select Local > Remote Control (see Figure 12).

3. Connecting to the Robot Controller from MachineMotion

With the Universal Robot controller now configured to be externally controlled, Vention’s MachineMotion v2 controller can now configure the robot directly in the Control Center, similialrly to any other Vention actuator.

3.1 Configuring a Robot

Step 1: Navigating to the Configuration page

On the Conrol Center main menu, select Machine Configuration (see Figure 13). You may also select Configuration if not on the main menu page.

Step 2: Adding a Robot

On the Configuration page, select Add Robot. A Robot configuration card should appear (see Figure 14).

Step 3: Applying the Configuration

Select the robot type from the Robot Model dropdown (see Figure 15a). The UR3e, UR5e, UR10e, and UR16e models are all currently supported. A friendly name can be given to the robot by typing in the Robot Name field. Once complete, select Apply All Configurations.

The robot may take a moment to connect. If everything above was properly done above, the robot configuration card will show a successful connection status (see Figure 15b).

You are now ready to program your Universal Robot directly in MachineLogic alongside other Vention components!

3.2 Troubleshooting

If the robot connection fails (see Figure 16), there could be a few reasons that are the root cause:

• The robot controller is still in Local mode, and not in Remote Control - See 2.5 - Step 3 to enable Remote Control.
• The Universal Robot Program (.urp) is not playing on the robot controller - Make sure everything is properly connected, as the program should play immediately.
• The IP addresses set in 1.2 and 2.2 - Step 2 are incorrectly set. Verify that the correct IP address was entered for both the network and URCap host.
• The Robot Safety Module is not properly wired, not allowing proper communication. Verify your system wiring per section 1.1.

If a robot has been previously configured and connected, and any of the above occurs, simply delete the configuration card. Follow from 3.1 - Step 2 onward to re-configure the robot.
