Modbus TCP port, configurable
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 PAC2200 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.
