I have devoted considerable time to resolving an issue, but have yet to find a solution. Recently, I successfully accessed the 1500 on the PanelView through the serial drive connections. However, when attempting to run my program while connected to the PLC, I encountered the error message "Can't autoconfigure to COM2". Despite selecting COM2 on both the PanelView and in FactoryTalk, this issue persists. Any insights on why this error is occurring would be greatly appreciated. Thank you for your assistance!
I am utilizing a serial to USB adapter for this task.
From my experience, this could be due to a conflict with another device also using COM2. Try to identify if any other devices connected to your computer are assigned to COM2. You can either reassign the port for the conflicting device or change the COM port in PanelView and FactoryTalk. Additionally, ensure your drivers are updated, as this could cause communication glitches. If the issue persists, a full re-install of the FactoryTalk software could be a possible, albeit time-consuming solution.
It sounds like your program might be attempting to connect to COM2 while it's already being used by another device or application. Make sure that COM2 is not being used elsewhere, and if the problem persists, try connecting on another COM channel, if available. Also, make sure that the communication settings (like baud rate, parity, and stop bits) are identical both on PanelView and your FactoryTalk setup. If all that doesn't work, consider testing with a different cable or check the device drivers - sometimes the issue could be as simple as a faulty cable or outdated drivers!
It sounds like your issue may be due to a conflict with another device that's also trying to use COM2. This can happen if you have multiple devices connected to your computer, each requiring a COM port. If you haven't already, I'd suggest trying to manually assign a different COM port to your PanelView in the device manager. Once done, correspondingly change the settings on FactoryTalk. It's a fairly common problem and hopefully, this approach resolves your issue.
It sounds like you're really diving deep into the troubleshooting! The "Can't autoconfigure to COM2" error could stem from a few things—have you verified that the serial settings (baud rate, parity, etc.) on both the PanelView and PLC match? Sometimes a mismatch there can cause communication issues. Also, double-check the physical connections; it's easy to overlook a loose cable or connection. It might be worth trying to reboot both devices after adjusting the settings just to ensure they’re on the same page. Hope this helps!
