I am in possession of an AB pvp31623, model 2711p-t7c22d9p-b, and I am currently attempting to activate VNC on my desktop. However, each time I try, it prompts me for a password and none of the passwords I have attempted have been successful. I have also observed that others facing this issue typically resolve it by going to desktop access and selecting "allow", but I am unable to do so as the button appears greyed out. Additionally, I am unable to toggle desktop access as it is currently stuck on disabled. How can I rectify this problem and enable desktop access? Despite attempting to reset the password and security question, the issue persists and I am unable to gain access to enable desktop access.
Performing a factory reset is essential for resetting the password on your HMI, but it will also erase all data on the device. Therefore, I suggest proceeding with caution and having the firmware version, program, and configuration settings on hand before initiating the reset.
The B Series PanelViews have encountered challenges with VNC functionality. If your firmware version is 12.102 or earlier, VNC cannot be activated. To enable VNC, upgrade to firmware version 12.105 or above. For steps on enabling VNC, refer to ID QA63564. We hope this information is helpful in resolving any issues.
Based on your description, it seems like you might not have administrator rights on your desktop. VNC and other remote management software typically need such permissions to change settings like desktop access. Try logging in as an admin or request the necessary permissions from your network administrator. If you're already the admin, ensure the panel view is in Runtime or Config mode. Also, ensure your firmware is updated. If the issue persists, reaching out to AB tech support could be helpful, they might have more targeted information or alternatives.
It sounds like you're dealing with a tough situation. Have you tried accessing the terminal and using the command "vncpasswd" to set a new password? If this doesn't fix it, it could be a more ingrained problem with user permissions or software bugs. You could also check if there are any firmware updates available for this model, as sometimes manufacturers release updates to fix common issues like this. If things still don't work, it might be worth getting in touch with customer support. Don't feel discouraged, troubleshooting tech problems can get a bit tricky, but there's usually a solution out there.
