ASComm.NET - Siemens S7 Driver for .NET Framework Developers
Automated Solutions ASComm.NET is a fully-managed .NET component that delivers communications connectivity between .NET applications and a broad range of industrial devices (PLC, PAC, Instrumentation, etc.) using popular communications protocols.
Visual Studio developers can now quickly and easily build HMI, SCADA, Historian, MES, ERP and other custom applications using ASComm.NET for the communications engine.
All supported protocol drivers are implemented in the ASComm.NET component, providing a single, consistent API regardless of the underlying protocols or hardware devices. Each driver can be licensed individually, so you only pay for the drivers that you are developing with.

Drivers available for the following brands/models
- Allen Bradley ControlLogix, CompactLogix, GuardLogix, Micro800 via Ethernet
- Allen-Bradley PLC-5, SLC 500, MicroLogix via Ethernet

Simple Code Examples
C#
// Declare using statement
using SIS7 = AutomatedSolutions.Win.Comm.SI.S7;
// This functions creates all required ASComm objects,
// sets initial properties, performs a write and read,
// then disposes the ASComm objects
void SimpleReadAndWrite()
{
// Create a Channel
// Siemens channels have no settable properties
SIS7.Net.Channel myChannel = new SIS7.Net.Channel();
// Create a device
// Preset properties to S7-1200 CPU at IP Address 192.168.0.121, rack 0, slot 2
SIS7.Device myDevice = new SIS7.Device("192.168.0.121,0,2", SIS7.Model.S7_1200);
// Create Group
// Preset properties to 500 mSec update rate and active flag set to false.
SIS7.Group myGroup = new SIS7.Group(false, 500);
// Create an item
// // Preset hardware tag name (data block) to 'DB3.DBB4', elements to 1, and data type to byte
SIS7.Item myItem = new SIS7.Item("DB3.DBB4", 1, DataType.BYTE);
// Add device to channel
myChannel.Devices.Add(myDevice);
// Add group to device
myDevice.Groups.Add(myGroup);
// Add item to group
myGroup.Items.Add(myItem);
//Write one tag
try
{
// Perform a write with value from text box
myItem.Write(textBoxItemWrite.Text);
}
catch (Exception ex)
{
// Error occurred, implement error handler
}
// Read one tag
try
{
// Perform a read, save value to text box
myItem.Read();
textBoxItemRead.Text = myItem.Values[0].ToString();
}
catch (Exception ex)
{
// Error occurred, implement error handler
}
// Dispose channel at application shutdown
myChannel.Dispose();
}
