How to Troubleshoot Failed Standard Interface Communications?

Problem

Some robot brands may provide two Ethernet ports such as port 1 and port 2 on their CPU motherboard. The Ethernet cable is plugged into port 1, but an IP address that matches port 2 is specified.

Solution

Open the controller and ensure that the port into which the Ethernet cable is plugged matches the specified IP address.

Problem

Some IPC brands may provide two Ethernet ports such as port 1 and port 2 on their CPU motherboard. The Ethernet cable is plugged into port 1, but an IP address that matches port 2 is specified.

Solution

Repeatedly plug and unplug the IPC’s Ethernet cable while observing the network adapter panel to monitor the connection status. This way, the correspondence between ports and IP addresses can be determined.

Problem

The firewall of the IPC determines that the connection between the vision system and the robot is malicious and then closes the connection.

Solution

Disable all firewall settings or configure proper firewall rules. For more information, see How to Troubleshooting Failed Communications Caused by Firewalls?

Problem

When the settings of the router are improper, the communication cannot be established.

Solution

Disable the router and then test the direct communication between the vision system and the robot. If the direct communication between the vision system and the robot can be established, test the communication of the two sides using a router. If the communication of the two sides using a router fails, see the router manual to check the router settings.

Problem

The IP address or subnet mask settings of the IPC or the robot are improper, causing them to be on different subnets and preventing communication.

Solution

Check the IP address and subnet mask settings of the IPC and the robot to make sure that the two IP addresses reside in the same subnet, and then test whether the communication can be established by using the two IP addresses. If the communication can be established, the two IP addresses are valid.

Problem

The communication cannot be established because the robot communication was improperly configured.

Solution

Make sure that the specified protocol, IP address, and port number are correct. For more information, see How to Configure IP Address and Port Number?

Problem

The robot communication configuration (i.e. the standard interface service) is not enabled in the toolbar of Mech-Vision. As a result, the communication cannot be established.

Solution

Make sure that the switch shown in the above figure is turned on.

Problem

When a Standard Interface program file is being loaded to a robot that contains the same program, the loading will fail because the same program is being used.

Solution

On the teach pendant interface, disable the foreground or background program for the robot.

Problem

When the incorrect Standard Interface program file is loaded, the communication will fail.

Solution

On the teach pendant interface, make sure that the correct Standard Interface program file is loaded to the robot system.

Problem

After you loaded the Standard Interface program, you did not change the IP address and port number in the program file or you specified incorrect IP address and port number.

Solution

On the teach pendant, make sure that the IP address in the Standard Interface program file is the actual IPC IP address and the port number in the file is the port number set in the communication configuration of Mech-Vision.
