Most shops still move programs the hard way: a USB stick walked out to the machine, a laptop with a serial cable, or a shared folder nobody trusts. Older controls have no network stack at all — the serial port is the only way in — so every transfer is a manual errand and nobody can say which revision is actually loaded on which machine.
Upload a program once; send it to any machine from the browser. A small agent sits beside each control, holds an outbound connection to the cloud, and delivers programs over RS232. The machine itself needs nothing new — no network card, no control upgrade, no changes on the shop-floor firewall beyond ordinary outbound traffic.
Every transfer is logged, so the question “what is running on that machine?” has an answer.
In development. If serial-port program transfer is a daily chore in your shop, we would like to hear how you do it today.
