"TCP/IP settings" parameter
Ports are communication channels which make it possible to access a Modbus-capable device
via a network.
Standard IP ports like port 502 are often tested by port scanners. If an open port is discovered
by an attacker, the device can be attacked via this port. The PAC3200T allows the Modbus
TCP ports to be configured manually. Switching from standard port 502 to a user-defined port
makes it more difficult to scan for open ports. The Modbus TCP communication port 502 is
used as the default setting.
