USB To RS485 PLC Programming Cable – USB-PPI Adapter For Siemens S7-200 Controller

Hey there, automation nerds and DIY machine builders!

If you're still messing around with old serial ports to program your Siemens S7-200 PLC, it's time to join the 21st century.

This little cable is exactly what you need.

It's a USB to RS485 adapter, specifically made for the PPI protocol that the S7-200 speaks.

Just plug the USB end into your laptop, connect the other side to your PLC, and you're ready to upload your ladder logic.

No drivers?

Probably plug-and-play.

It's a generic, unbranded cable, but for something like this, it either works or it doesn't.

And this one works.

It's brand new, still in the bag.

Keep it in your toolkit as a spare or use it as your main programmer.
