plc.Struct()...

Variable does not update its state if it changes twice a cycle tick.

Vars without network connection like Local

With Structures http://infosys.beckhoff.com/content/1033/tcsample_net/html/twincat.ads.sample09.htm

IAdsTransport or something similar

[???(AmsNetId:"5.2.2.2.1.1", DefaultPort:801)] public class RemoteDataSource{ ... }

List, add, remove...

Through the Windows registry x64: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Beckhoff\TwinCAT\Remote x32: HKEY_LOCAL_MACHINE\SOFTWARE\Beckhoff\TwinCAT\Remote

Something like this: new PLC("5.1.1.1.1.1", DefaultPort: 801);

We don't know when the variable has an actual value.
