Encountering a problem with TIA Portal V18 where the online icon is greyed out, but PLC communication is necessary as the blocks are being displayed and there is no offline copy stored on the laptop.
User Rs5212 reported a problem with TIA Portal v18, where the online icon is greyed out despite PLC communication being established. The blocks are visible, and there is no offline copy on the laptop. Can you provide a screenshot for clarification? Your message is not clear.
If you see blocks without a project in the Online Access tool while accessing your CPU online, you are already connected over the network. The glasses icon represents Monitoring, but this feature is not accessible through the Online Access tool, from what I have seen.
I'm attempting to connect online with a project I've already set up, but I don't have a copy of the PLC program on my laptop. Could this be why I'm unable to go online, even though I can still access PLC details?
Consider sharing a screenshot of your current view to help us better understand the situation. This can provide clarity and assist in resolving any issues more effectively.

It sounds like you might be dealing with a connectivity issue. I had a similar issue before and resolved it by checking the active network connection in the Control Panel. If the PLC is on a different subnet, make sure your laptop is set appropriately. Additionally, you can try opening the "Accessible Nodes" window in TIA Portal to verify the PLC connection. If the PLC is not visible, it might be an indication of a network issue.
It sounds like you're having quite a challenging situation. In my experience, communication issues like that could be due to several factors. One common cause is the proper drivers not being installed on your laptop. You might want to check that first. Alternatively, an incorrect network setting could also cause problems in PLC communication. I would suggest reviewing your network configurations to ensure everything is set up correctly. Lastly, ensure TIA Portal and your PLC firmware are updated to their latest versions, as this can oftentimes resolve the issue.
It sounds like you're experiencing connection issues between the TIA Portal and your PLC. Have you checked the network settings between your PLC and computer? A common issue might be a mismatch in IP addresses or an unstable connection. Additionally, try restarting both your computer and the PLC itself. If none of these solutions work, it may be a good idea to reinstall TIA Portal or update it to the latest version, and remember to always keep a backup offline copy to avoid such inconveniences.
It sounds like a frustrating situation! If the online icon is greyed out, first make sure your PLC is powered on and properly connected to your laptop via Ethernet. Sometimes simply restarting the connection or the TIA Portal software can resolve communication issues. If that doesn’t work, check your project settings to ensure the correct device is selected and that the right network configuration is in place. You might also want to look into any firewall settings that could be blocking the connection. If all else fails, temporarily downloading a backup of your project from the PLC could help you create an offline copy for future reference. Good luck!
I’ve run into that issue before; it can be really frustrating! Sometimes, the greyed-out online icon means there’s a communication issue between the TIA Portal and the PLC. Double-check your project settings to ensure you’re pointing to the correct PLC and that the right drivers are installed. Also, try disconnecting and reconnecting the USB or Ethernet cable if you haven't yet—it can often resolve these connectivity hiccups. If everything seems fine, a quick restart of TIA Portal might help jog it back to life!
I’ve run into that issue before; the greyed-out online icon can be frustrating! First, check your USB or Ethernet connection to the PLC, as it may not be recognized properly. Also, ensure that your project is set to the correct device type and that you're using the right runtime version on the PLC. Sometimes, a simple restart of the TIA Portal or re-establishing the connection can do the trick. If that doesn’t work, consider checking for any pending updates or patches for TIA Portal that might resolve communication issues. Good luck!
