It is a MicroLogix 1400.
Did you actually use the address B15/240 or B3/240?

Copy the entire 'Debug' folder, not just individual files.
Verify the connection between PC#2 and the PLC.
Ensure that the .NET runtime is installed on PC#2.

Tips & Tricks / Re: A guide on how to properly read and extract data from a barcode reader.
« on: March 17, 2025, 09:41:21 AM »
If you're using an ASCII serial-to-Ethernet device like the RTA-435NBX to connect to the barcode reader, refer to this link for setup instructions.
https://www.advancedhmi.com/forum/index.php?topic=2695.0
If your RTA module is set up the Data Type as a SINT array instead of a STRING,
its length is stored in at index [[0] and the actual barcode data begins at index [2].

If you are using a PLC serial connection to communicate with the barcode reader,
First check the buffer for any available characters.
If data is present, read it into the BarcodeString.
Finally, clear the buffer to ensure it's ready for the next scan.

Barcode scanners typically store scanned data in a SINT array.
In general, the data length can varies, a direct COPY without knowing its exact length is not feasible.
To transfer the barcode data from the SINT array to a STRING and set its length correctly:
After scanning, the FSC is used to locate the position of the last char in the SINT array.
If .FD is true, the position corresponds to STRING.LEN.
If it's not found & .DN is true [ie. Full string LEN], then Position + 1 determines STRING.LEN.
Next, Extract the content of BarcodeString to SerialNumber, PartNumber, ProductCode, PartCode using a delimiter such as 'Space'.
Noted that FIND can not find a NUL character.

Support Questions / Re: Issue with Advanced HIM and Linux mint
« on: December 04, 2024, 06:56:27 PM »
Have you restarted the system to ensure the changes are applied? I’m assuming you’ve already run update and upgrade.
Since this is an older PC, what baud rate did you configure for the port? Instead of testing with AAHMI, try using a basic terminal program like minicom to test the connection. You might also want to test a different port to rule out hardware issues.
It seems the Waveshare serial adapter uses either the FTDI or CH340 chipset, so make sure the appropriate driver is installed and functioning correctly.

Your response only partially addresses my question. I’ll assume you are not running a live session from your AIO PC and have instead installed a permanent version of Linux Mint. Here are a few suggestions you can try:
Add your username to the dialout and tty groups.
Disable pwrstatd.
Remove brltty.
