01 1 PLC/device port mapping
PLC/devices support multi client communication. For the security of the device, it cannot be directly connected to the external network. A network device needs to be physically isolated before it can be connected online.
02 Mapping multiple devices with the same port to multiple ports
There are multiple PLCs within the device LAN, and each PLC uses a small number of ports to communicate with the upper computer/server. Map the same port of the device to different ports externally, and distinguish devices based on ports.
