MindConnect Element cannot onboard to MindSphere

Network connection problem:

  • Either IP address is not valid or configured IP address already exists in the network of MindConnect Nano

  • Either disabled or invalid configured Proxy

  • Proxy is offline

  • Interrupted connection

  • IP address is configured via DHCP, but there is no internet connection.

  • Firewall blocks MindConnect Elements

  • Your company’s router is damaged

Although an asset is onboarded, no time series are uploaded to Fleet Manager and Visual Analyzer.

No connection to data source

Check the connection between MindConnect Nano and data sources (Plant Network ports and cables - S7/OPC UA Server)

The address of the data point configuration can be incorrect

  • Check the connection between MindConnect Nano and data sources (Plant Network ports and cables - S7/OPC UA server)

  • Check data sources configuration.

  • Check configuration of each data point.

MindConnect Nano/IoT2040 cannot onboard to MindSphere

  • Incorrect asset configuration

  • Not accomplished asset configuration (Network Connection)

Check configuration of your asset (Network Configuration).

Firmware update error

  • Technical problems with a new version of firmware

  • Incorrect firmware type

  • Certificate problems, Authentication problems etc.

  • Make sure that you are using the correct firmware type (MindConnect Nano/IoT2040).

  • MindConnect Nano/IoT2040 will automatically restart and then firmware update will be carried out after a while.

  • If MindConnect Nano/IoT2040 does not restart automatically, then restart it manually: by switching on and off the “power button” on MindConnect Nano and by switching off/on the power supply for MindConnect IoT2040.

Onboarding failed

  • Configuration file on the USB stick is invalid

  • Internal error

  • Make sure that the data on the USB stick still is valid. (The data, which you exported to the USB stick, is still valid only for 7 days.). If it is expired, use the asset configuration to export a new valid configuration to your USB stick.

  • Check asset configuration and reconfigure, if it is required and export a new configuration to USB stick

Problems with USB stick

  • Incorrect formatting of USB stick (no FAT or FAT32)

  • USB stick is damaged

  • Write error, USB stick is write-protected or its memory is full.

  • Configuration file is invalid (damaged, illegible)

  • See also below

  • Check format and partition of the USB stick. It must be FAT or FAT32 formatted and may only contain a single partition.

  • Try a new USB stick

Although no LED lights are shown (except PC ON/WD with constant GREEN) and internet connection is OK, MindConnect Nano still cannot be onboarded to MindSphere

Problems with USB stick:

  • Configuration file in USB stick cannot be read or accepted by MindConnect Nano:

  • Problems with configuration file

  • Configuration file is located in an incorrect directory.

  • Expired configuration file on the USB stick

  • The configuration file is invalid or not copied to the USB stick

  • Remove and plug an USB stick into MindConnect Nano

  • Check the diagnosis file on the USB stick.

  • Check the name of the configuration file. It must have MindConnect Nano ID. Do not change the name of the downloaded file.

  • Check whether the directory is valid. (Configuration file must be in the root directory of the USB stick.)

  • Make sure that the data on the USB stick is still valid. (The data, which you exported to the USB stick, is still valid only for 7 days.) If it is expired, use the asset configuration to export a new valid configuration to your USB stick.
