PLC stands for Programmable Logic Controller which is a manufacturing term
for computer controlled machine.  This is sorta like a robot but not
exactly the same.  Anyway, from what I know PLCs talk to computers over
dedicated async serial lines and download code with a simple send
block/ack type of protocol.  At least that is how they worked a few years
ago.
