Problem with the online connection to Power Panel 65

Hi,

if you ping the IP address, do you get a sucessful ping response?

If no, please first again check the IP settings of the notebook and the cableing / LEDs of the ethernet ports (at least one LED, the LINK LED, should be on).
You could also check out the following post.to check if anything is communicating on the network:

If yes, maybe the port settings of the PLC differ from default. To check what ports are open, you could use a port scanner like Zenmap to scan the IP address, maybe this helps for further investigation.
A list of the PLCs default ports can be found here.

Best regards!
