Because its a simple and cheap way to control unmanned installations

I mean here on the UK Fens there are many many sluice gates and pumps 
that should operate automatically on float sensors, but I suspect are 
also monitored and controlled centrally.

No one ever thought anyone would have any interest in  hacking them.

Siemens are a pretty shoddy firm anyway.

One would have thought they had some some form of authentication and 
encryption and indeed firewalling going on. There is no need to expose 
such devices to the whole Internet...
