Allen-Bradley, Siemens S7, GE, & Modbus Communication Drivers for .NET Developers

Product Summary

Automated Solutions ASComm.NET is a fully-managed .NET component that delivers communications connectivity between .NET applications and a broad range of industrial devices using industrial communications protocols.

All supported protocol drivers are implemented in the ASComm.NET component, providing a single, consistent API regardless of the underlying protocols or hardware devices. Development licenses for each driver can be licensed individually, so you only pay for the drivers that you are developing with.

Use Visual Basic, C#, C++, and ASP.NET to create HMI, SCADA, data logging, and IIoT applications targeting Win Forms, WPF, Web, console, service, and Linux.

Powerful pre-built example applications with VB and C# source code included in development package.

Runtime-free for qualified applications

License Types

Full Development License

Allows for application development on a single PC and runtime deployment to multiple PCs.

Runtime license is embedded into executable, so no licensing steps are performed on runtime PCs.

Who should purchase

  • End users that require runtime-free deployment within their organization.
  • Equipment OEMs, machine builders, and system integrators building applications that qualify for runtime-free distribution per license agreement.
  • Developers building applications that qualify for runtime-free distribution per license agreement.

Team Edition pricing is available for teams starting at two developers.

Commercial developers, please contact our to inquire about commercial licensing.


Single Machine License

Allows for application development and runtime on a single PC.

Cannot be used to build deployable applications (with embedded runtime license).

Who should purchase

  • Developers that will be developing and running their application on a single PC.
  • Developers building applications for customers where application source code is included.
  • Developers building applications that do not qualify for runtime-free distribution per license agreement.
