Generating virtual com-port in accesed device

How I can generate virtual com port in a device which is accesed on zerotier network.
For example I have my plc on site which I can ping from my office. I got the plc’s ping via a gateway device with zerotier configuration on site.Now , how can I take my plc online on rs232 communication after generating virtual com port in it.

welcome to the forum. I’m not sure I 100% understand, but it sounds like it’d be specific to your PLC.

One common similar solution is to have a device that runs zerotier and plug its serial port, or usb-to-serial, into the PLC. Then ssh into the zerotier device.
