This guide shows you how to load the Master-Control program and configuration files to a MELFA robot, and set up the Master-Control communication between the robot and the Mech-Mind Vision System.

TIP:

Preparation

Set up the Network Connection

Connect the Hardware

Use the Ethernet cable to connect the network ports of the IPC and the robot controller.

Set the IP Address on the IPC

The default IP address of the MELFA robot is 192.168.0.20. Therefore, set the IPC’s IP address to one on the subnet 192.168.0.0/255.255.255.0.

The IP addresses of the IPC and the robot should on the same subnet, but do not set the same IP addresses.

Create and Configure the Project

In this guide, the Master-Control program is loaded into the robot via the software RT ToolBox3. Therefore, before loading the program, you need to install RT ToolBox3.

  1. Install the software RT ToolBox3 onto the IPC.

    You may contact the robot manufacturer to obtain the software RT ToolBox3.

  2. Open RT ToolBox3. Click New on the menu bar, enter the workspace name and then click OK.

    If the connection fails, please double-check the robot IP address.

Move the Robot

  1. In the toolbar of Mech-Viz, change the “Vel.” (velocity) and “Acc.” (acceleration) parameters to 5%.
