TCP communication record

Started by tingxing, 11 Oct 2022

tcp

1 post in this topic

Posted 11 Oct 2022

Hello,

My PLC is connected to PC using ethernet port,

and the PC is requesting data (DMs) from PLC to do data logging.

I want to know if it is possible to check the latest TCP communication request's time stamp.

As a kind of something like handshake, so I can be sure the PC is still working.

Does Mitsubishi's PLC keep this kind of data anywhere?

Thanks in advance.

Ting
