What happened?
hello sir!
When attempting to connect my computer, the following threads are looping in retries:
14:40:00.335 [plc4x-s7ha-thread-1] INFO o.a.p.j.s.r.p.S7HPlcConnection - Creating prymary connection.

Is there an API available to terminate this connection, considering that the target is not an actual PLC but rather the IP address of my computer?

Hello, You can check the documentation [1] and examples in the repositories.
Additionally, you must document the failure including the connection URL.

sir， That means the IP in the URL must be that of the PLC. Otherwise, if the IP can be pinged but is not that of a PLC, the connection program will not stop.
The following is the log content：

I wouldn't say "not planned" I'll definitely look into this... Just not immediately
So I just tried connecting to an S7 on an IP address, that doesn't exist and the connection simply failed with "connection is not possible". So I can't confirm this loop that you are referring to. I both tried connecting to an existing IP that is not an S7 as well as a completely not existing. Both correctly report not being able to connect.
