+ Compatible S7 PLC (S7-200, S7-300, S7-400, S7-1200)
+ .NET Framework 3.5 or higher
## Basic Usage
```C#
string deviceIpAddress = "172.25.116.87";
int rackNumber = 0;
int slotNumber = 2;
using (var plc = new PLC(CPU_Type.S7300, deviceIpAddress, rackNumber, slotNumber))
{
//Ensure IP is responding
if (plc.IsAvailable)
{
ErrorCode connectionResult = plc.Open();
//Verify that connection was successful
if (connectionResult.Equals(ErrorCode.NoError))
{
//Get data
object data = plc.Read("MB59");
Console.WriteLine("SUCCESS: Read result of MB59 is {0}", data);
}
else
{
Console.WriteLine("ERROR: Device is available but connection was unsuccessful!");
}
}
else
{
Console.WriteLine("ERROR: Device is not available!");
}
}
```
