Subject: Assistance Needed for Multiple Device Errors Hello everyone, I’m reaching out for help with a few issues I'm facing. Here are the problems I'm encountering: 1. The display shows a black screen after the boot process. 2. I receive an error stating "unable to open communications port". 3. There’s another error indicating "the device does not contain an uploadable image". 4. Despite verifying that the settings in the attached image (picture 4) are correct, I still encounter the errors mentioned in points 2 and 3. I found a similar thread on PLC Talk (www.plctalk.net/qanda/showthread.php?t=94038), but unfortunately, I’m still unable to download or upload successfully. I appreciate any guidance or support you can provide. Thank you!
Are you observing any display during the boot process? If not, your device might be experiencing issues with the backlight. Does your unit emit a beep when powered on? Additionally, it's important to confirm whether your PC network settings are correctly aligned with the Human-Machine Interface (HMI). If the HMI lacks an installed application, connect it using a USB cable to perform an update, ensuring that you have the appropriate file ready to facilitate TCP downloads. For further assistance, please compress your CD3 file and attach it so we can analyze the specifics more thoroughly.
OkiePC inquired: Are you able to see anything during the boot process? If not, it’s possible that the unit has a faulty backlight display. Does it emit any beeping sounds upon startup? Are you certain that your PC’s network configurations align properly with those of the HMI? If there’s no application installed on the HMI, try connecting it with a USB cable to perform an update, and make sure you have the correct file ready for a TCP download. Additionally, if you can compress and attach your cd3 file, we can delve into the specifics further. Click to expand... Can you clarify what you mean by "beep"? Is the power-on process functioning normally? I am confident the network settings are correct. I will try using a USB cable. The image shows the screen before it turned black; after that, it went black, but the power remains on.
It appears that the backlight is not the issue. Could you please compress and send your CD3 file? I've encountered problems in the past when creating a startup program that involved inaccessible device tags or ran into circular reference errors. Reviewing the CD3 file would provide valuable insights.
OkiePC replied: "It appears the issue isn't related to the backlight. Could you please zip your CD3 file and attach it? I've encountered challenges in the past when launching a startup program due to inaccessible device tags or circular reference errors. Reviewing the CD3 file would be beneficial. Additionally, I attempted to use a USB drive, but the same problem persists, and I'm unable to download or extract files. How can I effectively download and upload files from the HMI? I followed the guidance provided in this thread: http://www.plctalk.net/qanda/showthread.php?t=94038, but unfortunately, I still can't download the file."
It sounds really frustrating to deal with all those errors at once! For the black screen issue, have you tried booting in safe mode or checking if there's a hardware connection that's come loose? As for the communication port error, double-check that the drivers are up-to-date and match your operating system. Sometimes, simply restarting the device can reset those ports if they're stuck. Lastly, for the uploadable image error, ensure that the correct firmware version is being used, as that can often cause compatibility issues. Good luck, and I hope you get it sorted soon!
