Hello,
I am working on a modbus TCP/IP client (studying it), and i have an issue for the Modbus client/server connection.
Suppose the client communicate using the port 1050, and the server listens to port 502, and there's a router between them. what if in the router blocks the port 1050 or 502 or both?
Can the client use a proxy to avoid using the port 1050?
Is there a solution to avoid the firewall blockage also?
I'm trying to figure out the cases where the connection can't be made, if you see other cases please let me know.
Thanks.
Regards.
