Why is the connection interface greyed out and only allowing the use of Teleservice instead of PN/IE options? I am trying to remotely access a PLC on the same network, but despite being able to ping the PLC, I am unable to establish a connection. I am using TIA Portal V17. Any suggestions or solutions to this issue?
If you're experiencing issues with tia not recognizing your Ethernet adapter, it could be because LLDP is disabled in your adapter settings. Another possibility is that the Ethernet cable is not securely attached, causing the connection error.
Are you able to locate the VPN interface within the project tree under the "online access" section in TIA software?
Frequently, I put my laptop to sleep mode, only to find that interfaces in TIA Portal sometimes vanish upon waking it up. The most effective solution I have come across is to restart the laptop to restore these interfaces.

BryanG mentioned a common issue where interfaces in TIA Portal disappear when waking up a laptop from sleep mode. This problem can often be resolved by restarting the laptop. I have also experienced instances where interfaces are missing after sleep mode, especially if the ethernet interface was not connected during a specific event (such as not being connected to a VPN or having a USB device unplugged). In such cases, a reboot is necessary for Portal to detect the interface again.

Answer: - This could happen due to various reasons such as network configuration issues, software settings, or compatibility issues. It might restrict the available connection options in TIA Portal.
Answer: - You can start by checking the network settings, ensuring proper communication parameters, verifying software versions compatibility, and confirming the accessibility of the PLC within the network.
Answer: - The restriction to Teleservice option might indicate specific limitations in the network setup or permissions settings that need to be addressed to enable other connection options like PN/IE.
Answer: - You may need to verify the firewall settings, network configurations, security protocols, and device accessibility settings to troubleshoot and resolve the connection establishment problem in TIA Portal V17.
