Add Sensor/Device to Network Dialog

The Add Sensor/Device to Network dialog allows you to configure In-Sight Ethernet devices. You can use this dialog to:

• Configure In-Sight devices for communication on a TCP/IP subnet or for a direct connection to a PC.

• Configure In-Sight devices with invalid network settings. These devices are automatically detected and displayed in the list. If an In-Sight device is power-cycled while the dialog is open, it is also added to the list.

  Tip: If the device does not automatically appear in the list, select the Show All radio button to display all In-Sight devices detected on the subnet.
• Reset the Admin password.
• Reset the In-Sight device to the factory default settings.

Add Sensor/Device to Network Dialog Controls

To display the Active Cells Limit dialog, click Add Sensor/Device to Network from the System menu. The fields in the dialog remain disabled until a device is selected in the list.

• Filter textbox: Filters all displayed columns. For example, if you type “2000-130C”, only the rows with the text (2000-130C) will display.

• Host Name: Specifies the name of the networked In-Sight device. Each device has its host name set automatically the first time it boots. You can change the host name by entering a new name into the field. Host names can contain a maximum of 63 characters. Valid characters for the host name are A–Z (upper and lowercase), 0 - 9, hyphen ('-'), colon (:), period ('.') and underscore ('_').
• Obtain IP Address Automatically (DHCP): Specifies that the network settings of the In-Sight device will be configured dynamically by the DHCP Server on startup. For more information, see Dynamic IP Address or Dynamic Host Configuration Protocol (DHCP) Server
• Use the Following Network Settings: Specifies that the In-Sight device will be configured according to the network settings configured below.

  • IP Address: Specifies a unique identifier for each In-Sight device on the network, which must be consistent with the IP address-numbering scheme of the local network.

    Note: If the vision system/sensor is assigned an IP address by a PLC over ProfiNET and the vision system/sensor is power-cycled, ProfiNET assigns an IP address of "0.0.0.0". You can configure the vision system/sensor to use a valid IP address in the Add Sensor/Device to Network dialog. When power-cycled, the new IP address is properly retained.

  • Subnet Mask: Defines which part of the IP address refers to the network and which part refers to the host. The network part of the IP address is the same for all hosts on the same subnet, and the remainder is unique to each host. 

    There are three classes of subnet masks. The class of a particular subnet on a network is defined by the number of bits used to represent the network and host address portions in the IP address, as in the table below:

    Class	Subnet Mask	Network Address	Host Address
    A	255.0.0.0	8 bit	24 bit
    B	255.255.0.0	16 bit	16 bit
    C	255.255.255.0	24 bit	8 bit

    For example, consider a networked In-Sight host system with the IP address 192.168.0.1. If the first three numbers (192.168.0) identify the 24-bit network address, and the last number (1) is the 8-bit address for the In-Sight host on the network, then the subnet mask for this host is 255.255.255.0.

  • Default Gateway: Specifies the IP address of the gateway host, if available on the network. The gateway host is responsible for relaying data between hosts on different networks. If an In-Sight device needs to communicate with a device on a different subnet, enter the address of the gateway device in the Default Gateway field. Otherwise, leave the field blank.
  • DNS Server: Specifies the IP address of the host on the network providing DNS resolution, if available. For more information, see Domain Name Service (DNS) Server.

  • Domain Name: Specifies the network domain for the host network. Domain names can contain a maximum of 63 characters. For more information, see About Domains.

• Copy PC Network Settings: When enabled, specifies that all the network settings for the In-Sight device (except for the host portion of the IP address) will be configured according to those of the local computer.
• Reset Admin Password: When enabled, resets the admin password for the In-Sight vision system to the factory defaults (blank). For more information, see User Access Settings Dialog.

• Reset Sensor Settings to Factory Defaults: When enabled, resets all the settings for the In-Sight vision system (except for the network settings in this dialog) to the factory defaults. For example, user list, discrete I/O, date/time, host list, serial and FTP settings will all be reset. For more information, see PROC.SET

  Note:

  • This option is disabled for the CIO-MICRO and CIO-MICRO-CC I/O modules.
  • The In-Sight emulator can be reset to the factory defaults using the Emulation option on the Restore Defaults dialog accessible from the Options dialog. For more information, see Restore Defaults.
• Flash Lights: Causes the LEDs on the In-Sight device to flash, to help you visually locate it. This button toggles to the Stop Flashing button, and the LEDs continue flashing until you do one of the following: click Stop Flashing, close the Add Sensor/Device to Network dialog or select another device in the list.
• Refresh: Refreshes the list of In-Sight devices.
• Show All: Displays all In-Sight devices detected on the subnet.
• Show New (default): Displays In-Sight devices with invalid network settings on the subnet. An In-Sight device that is power-cycled on the subnet while the dialog is open is also added to the list.

Reconfigure Invalid Network Settings

1. Verify that your device is physically connected to the network.

2. Open the Add Sensor/Device to Network dialog and select the device from the list. If the device does not appear in the list, select the Show All button or power-cycle the device.

   Note: When cycling power on the In-Sight 70xx - 74xx series vision system, Cognex recommends that the power be disconnected for at least 5 seconds.
3. Verify that the host name is correct.

4. Use either a dynamic or a static IP address for the device.

   For a dynamic IP address:

   1. Select Obtain IP Address Automatically (DHCP), which enables the DHCP server to dynamically configure the device on startup.

   For a static IP address:

   1. Select Use the Following Network Settings.
   2. Enter an IP address.
   3. Do one of the following:
   • Select Copy PC Network Settings, which automatically assigns the local computer's subnet mask, default gateway, DNS server and domain name to the device.
   • Contact your network administrator for the subnet mask, default gateway, DNS server and domain name and enter them manually.

5. Click Apply.

   Note:

   If the selected vision system is running firmware 3.4.x or earlier:

   • A dialog will appear, indicating that the vision system settings will automatically be reset to the factory defaults.
   • A progress bar will appear, prompting you to cycle power on the vision system (as a result of the power cycling, the dialogs mentioned in steps 8 and 9 will not appear).
8. In the confirmation dialog that appears, click OK.
9. In the verification dialog that appears, click OK.

Reset In-Sight Vision System Settings to the Factory Defaults

Selecting this option will reset all the settings for the In-Sight vision system (except for the network settings in this dialog) to the factory defaults. For example, user list, discrete I/O, date/time, host list, serial and FTP settings will all be reset. One possible application is if you have forgotten the password to a vision system and want to revert to the default, which is <blank>.

1. Verify that your device is physically connected to the network.

2. Open the Add Sensor/Device to Network dialog and select the device from the list. If the device does not appear in the list, select the Show All button or power-cycle the device.

   Note: When cycling power on the In-Sight 70xx - 74xx series vision system, Cognex recommends that the power be disconnected for at least 5 seconds.
3. Select Reset Sensor Settings to Factory Defaults.
4. Click Apply.
5. In the confirmation dialog that appears, click OK.
6. A progress bar appears; cycle power on the vision system, as prompted, so the configuration changes take effect.
7. Note: When cycling power on the In-Sight 70xx - 74xx series vision system, Cognex recommends that the power be disconnected for at least 5 seconds.
8. In the verification dialog that appears, click OK.
