Loading the Project Sources from the PLC’s SD Card into the PC

  1. Insert the SD Card into the CPU (if not already inserted).

  2. Start the Control Builder PS501 (CoDeSys.exe).

  3. Select “File” => “Open”.

  4. Click “PLC”.

  5. Select the required CPU type (target), for example PM581.

    f40975c4e38c28ca0a33139000473a6a_baeeb48ee38c27730a33139000eba54e

  6. Select the communication channel, for example an Ethernet channel.

    f40975c4e38c28ca0a33139000473a6a_e954e4e7e38c24d40a33139000eba54e

    ⇒

    The project sources are loaded block-wise.

    ../_images/86f5f2c8e38c27c10a33139000eba54e

    Once the last block has been loaded, the project is decompressed by the software automatically. Now all project files are available.

    ../_images/9d07c22de38c27150a33139000eba54e

You can use this project to directly login to the CPU (no build required).

Note

If you want to change the project, save it under a new name, change and build the source code and then download the changed and built code (user program) to the CPU. Reload the boot project and the project sources.
