# s7netplus
|
|
#### A .NET Library for Siemens S7 Connectivity
|
|
|
|
## Overview
|
|
|
|
S7.Net Plus is a continuation of the work done on the [S7.Net](http://s7net.codeplex.com/) project by [Juergen1969](http://www.codeplex.com/site/users/view/juergen1969).
|
|
I found the library simple and effective, but the project has languished unchanged since late 2009.
|
|
|
|
I was doing some automation work already and saw a few places where the code base could be improved. Because Juergen did not respond
|
|
to my request for committing code, I decided to pick up where he left off here on GitHub.
|
|
|
|
## Requirements
|
|
|
|
+ Compatible S7 PLC (S7-200, S7-300, S7-400, S7-1200)
|
|
+ .NET Framework 3.5 or higher
|
|
|
|
## Nuget
|
|
|
|
PM> Install-Package S7netplus
|
|
|
|
## Basic Usage
|
|
|
|
```C#
|
|
//Basic connection properties
|
|
string deviceIpAddress = "172.25.116.87";
|
|
int rackNumber = 0;
|
|
int slotNumber = 2;
|
|
|
|
//Connection to device
|
|
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!");
|
|
}
|
|
}
|
|
```
|
|
|
|
## Running the tests
|
|
|
|
Unit tests use Snap7 server, so port 102 must be not in use.
|
|
If you have Siemens Step7 installed, the service s7oiehsx64 is stopped when running unit tests.
|
|
You have to restart the service manually if you need it.
