Connection lost?

If you have lost the connection with the Asycube, robot, PLC or EYE+ Studio, try to check if they are correctly configured.

Note

If you have lost the connection with the camera, go directly to section Camera connection lost.

To do this, connect directly to the device with an Ethernet cable. Configure your computer to be under the same network as the connected device. Open the terminal and ping the device to the IP address on which it is supposed to be configured. For example, to ping the Asycube you must enter in your terminal the command ping 192.168.127.254.

Tip

Check General Ethernet Settings for the default configuration of the EYE+ Controller Ethernet ports.

If your device is correctly connected, the command answer should look like this:

If not, your device is not properly configured or not correctly connected, please refer to the appropriate section below.

Camera connection lost

Since the IP address of the camera cannot be changed, you have probably lost the connection with it. Reboot the camera by unplugging the cable. Wait a few seconds and reconnect the cable. After a moment, check your connection through EYE+ Studio on the HOME page. The status of the camera is directly visible on the first section.

The camera LED should start flashing green. If not, check Connection status of the camera for the corresponding status.

Asycube connection lost

Try first to reboot the Asycube by power it off and unplugging the Ethernet cable. Wait a few seconds and reconnect the cables. After a moment, check your connection through EYE+ Studio on the HOME page. The status of the Asycube is directly visible on the first section.

Table 32 Default Asycube Ethernet configuration

IP address	Subnet mask	Port
192.168.127.254	255.255.255.0	4001

If the Asycube is still not detected, your Asycube is probably no longer configured with the default IP address and port. You must change the configuration of your Asycube to match the Default Asycube Ethernet configuration.

Refer to recover IP address to set it back to its default IP address.

TCP/IP communication connection lost

If you loose the TCP/IP communication connection, check the robot or PLC configuration. You must set the configuration so that it is on the same subnet as the EYE+ Controller port where it is connected. Check the General Ethernet Settings or directly in EYE+ Studio on Communication Configuration.

You can make the necessary changes on the robot, PLC or EYE+ depending on your application and the other connected devices.

EYE+ Studio connection lost

If you lose connection to EYE+ Studio because you do not know the actual communication or config port configuration, you can use the EYE+ Locator to find your EYE+. Alternatively, you can still access EYE+ Studio using a direct connection via the Asyfill or Robot port.

Important

The Asyfill and the Robot ports are not dedicated to access EYE+ Studio, but it can be used if the communication port is not accessible anymore for any reason. Through this connection you will be able to read or edit the settings of the communication port.

Direct connection through Asyfill or Robot port

Direct connection is a direct Ethernet connection between your computer and EYE+. To do so, connect the RJ45 port of your computer to the RJ45 port of the EYE+ Asyfill or Robot port using an Ethernet cable. This port has a fixed default IP address (General Ethernet Settings).

Fig. 324 Direct connection through Asyfill or Robot port

Change the IPv4 configuration of your computer by choosing an IP address and subnet mask so that it is on the same network as the EYE+ Controller. For example, apply the configuration presented in Table 33.

Table 33 Example of IPv4 configuration (computer side)

Ethernet port	IP address	Subnet mask
Computer RJ45	192.168.0.1	255.255.255.0

Once your computer is properly configured, open your web browser and enter the IP address of the port (e.g. 192.168.0.50). The home page (Fig. 325) should appear.

Go to CONFIGURATION and click on Communication to access the Communication Configuration. From here, you can read or change the Communication port settings.

Note

If the home page does not have the same display as in Fig. 325, refer to Recommended web browsers and Interface display.
