Yes, thank you, I solved the previous issue. I added the passwords I had set for Communicator and WebStation to the Users section and granted all of them Administrator privileges.

However, I have another question. Right now, I am unable to upload because I changed the Username and Password in the Agent connection. I have also added these new Username and Password values to the Users section, but I still cannot upload. Could you please guide me?

Thank you for your response.
I’m absolutely sure that no other software is using the COM port.
I’ve created a new project many times. At the beginning, when I set up the serial port, I can see the data flow working correctly on the administrator application.
However, as soon as I configure the Channels and upload the code, I notice that COM3 is closed, but it does not reopen again.

I’m sharing the log and text record from Communicator here.
This part is after I uploaded the software.
Even so, in the Line State and Line Log tabs, nothing changes or new entries appear after the upload.
The message saying that the COM port is closed always remains as the last message.

This is SCADACOMM.log

I am using Windows 10 Pro on my computer. For the physical interface, I am using a classic USB-RS485 converter.
