OPC Client c# .Net Sample (RSLinx OPC server)

This is an example of communication with RSLinx OPC Server is the same for every OPC server).

Start by adding a reference to the OPC Foundation dlls:
- OpcNetApi.Com.dll
- OpcNetApi.dll
- OpcNetApi.Xml.dll
Then create Items that are shared for the all the form (or the project)

Then create a button to connect (or just place the code after InitializeComponent(); if you want to autoconnect when the program starts)
Set the URL (in this sample there is the one of RSLinx) then add a group, add some items with theyr connection string, set the update time and the callback for the items that you want to read, then set a group for writings.

This is the sample callback where i assign values that i read to a custom object.
Remember that the GUI and the OPC client runs on two different threads, so it's needed to use anonymous method for this (just use like is written in the sample).
With WPF and INotifyPropertyChanged it's not needed this.
You can just bind all your objects to the GUI items property, and this is really amazing and simple.

This is the way to write a single word, basically lucrate a new one, check if in the write group there is already one of them, else i add it.

This code is written on a Micrologix / SLC platform and it reads only integer values, so when i read a value it's supposed to be a 16-bit word: that's why i cast it to (short). Remember that if you read a REAL value (F8:0 for example) you sould cast it to float and if you read from Controllogix or CompactLogix, you have to convert it to (int) because they are 32-bit words.
