Error on connecting to Opta

Development Tools PLC IDE
1

Hi there,

I'm new op the Arduino PLC and OPTA system.
I have downloaded Arduino PLC IDE and installed it as an Administrator.
Then I run the software as an Adminitrator to and start a new project.

When the OPTA is connected, COM7 and COM8 are shown.
When I still have to connect the OPTA, they are missing and don't appear at al.
Also no after 30 minutes or so.

In OTHER I sellect COM7, all others are not working, and click DOWNLOAD.

After some minutes, the Compiling Sketch screen dissapears.

However the STATUS still shows "Please connect to the target"

Now I can Set the communication in On-Line and click OK.

After this I click Connect in the On-Line menu, the CONNECT button turns Green.

In the right corner a red ERROR shows.

According the manual, I now should see the connected OPTA.
When I disconnect and try connecting again the PLC-IDE software crashes.

What am I doing wrong?
I have tried several times and also removed and reinstalled the software.
Still no result.
Please let me know how to solve this.

Try to upload and run the Arduino IDE example STM32H747_System > QSPIFormat
and then the entire Arduino PLC IDE Process

Hi there,

After lots and lots of tests, finaly there is a connection.
I'm not sure what the solution was, I have tried many versions and tips.
However, now it seems to run.
Next step, some standard I/O tests to get used to te IDE.

The best way to investigate the connection are the serial output of arduino side.

Hello:

I'm like walbeek but I don't get out of ERROR in the lower right part.
I think it detects the port and I think it loads the firewall, but when I connect it doesn't go beyond the error and doesn't give me any more information.
I have reinstalled the software and it still gives an error
Any ideas?
Thank you

Hi everyone,

The first step in configuring Opta with the PLC IDE is to download the runtime.
If the error message mentioned by @walbeek appears in the status bar when connecting, it is recommended to implement the memory partitioning tutorial. Please ensure that the code execution is completed successfully by following the serial monitor output.

Then, you can follow the steps indicated in this tutorial to set up the board:

Note: It is necessary to activate the license after implementing memory partitioning.

Best,

Hi. Please help me out.

  1. Which version of the IDE are you using?
  2. Which version of the Opta are you using?
  3. What options did you select on the QSPI format menu?
  4. Which port/speed/parity did you use?
