No connection to Raspberry Pi from the development environment

This article gives you some clues how to proceed when it is not possible to connect to the →Raspberry Pi from within logi.CAD 3.

Symptoms:


Possible causes

Solutions

  • The SD card inserted into the Raspberry Pi does not meet the requirements.

  • The required additional equipment (e.g. the →PiFace) is not connected correctly to the Raspberry Pi.

  • The Raspberry Pi is not connected to the network.

  • The Raspberry Pi is not connected to the power supply.

  1. Make sure that the SD card meets the requirements as listed under "Hardware and software required for Raspberry Pi tutorial".

  2. Assemble the Raspberry Pi as described under "Assembling Raspberry Pi and detecting IP-address".
    Mind to first plug the network cable in and only then the power cable.

  3. Configure the Raspberry Pi as described under "Configuring Raspberry Pi".

  • logi.RTS is not installed and started on the Raspberry Pi.

  • logi.RTS is installed and started on the Raspberry Pi, but the installed version differs from the one required by logi.CAD 3.

Install and start logi.RTS on the Raspberry Pi as described under "Installing and starting logi.RTS on Raspberry Pi" but the version that is required by logi.CAD 3. The article "Release notes for version" contains information on the required version of logi.RTS.

No license for logi.RTS has been installed on the Raspberry Pi.

Install a license on the Raspberry Pi as described under "Installing and starting logi.RTS on Raspberry Pi".

Alternative: Start the Raspberry Pi again so that logi.RTS is re-started. This makes it possible to operate logi.RTS as demo version – as a full version for 3 hours after starting logi.RTS. Instructions how to start the Raspberry Pi are specified under "Installing and starting logi.RTS on Raspberry Pi".

A wrong IP-address has been entered for the Raspberry Pi within the PLC-object.

Enter the correct IP-address of the Raspberry Pi within the PLC-object as described under "Loading application onto Raspberry Pi".

You might have to load the application onto the Raspberry Pi after the above listed solutions: In the Instances view, select the item for the Raspberry Pi. If necessary, first click images/download/attachments/405733746/ConnectToPLC-version-1-modificationdate-1529910447299-api-v2.png and then images/download/attachments/405733741/LoadProgram-version-1-modificationdate-1529910412582-api-v2.png .

images/s/b2ic8e/9012/1ca6q62/_/images/icons/emoticons/information.svg logi.cals recommends to install and use the most current versions of logi.CAD 3 and the runtime system so that the latest features and problem fixes according to the release notes are provided in the used version.
