Look at AdvancedHMI. It is an HMI/SCADA Visual Studio toolkit with AB drivers. You can do most HMI stuff without writing code, but you can also use VB or C# for advanced tasks.

  • thank you for reply. Advanced HMI is company. I think, I can not use it on professional application in industry without pay. I did a scada in C# for siemens s7-1500. it is good. I think, same is possible for rockwell AB PLC. I dont use opc or any other interface between plc and pc. direct ethernet ip communication was used. I hope same thing is possible for AB. – ahmetnoktacom Feb 07 '18 at 05:27

Look at EEIP Library. They have a C# and Java library for Ethernet/IP communication. They even offer some videos on YouTube on how to use it. But be aware, that some of this free libraries have some rough edges or bugs with them. Personally, I would use Modbus or another PLC before using Ethernet/IP along with a PC.

There is an open-source project called libplctag which has a few .NET wrappers, some of which are on nuget: https://www.nuget.org/packages/libplctag/, https://www.nuget.org/packages/PlcTag.Net/

Full disclosure: I'm one of the authors of the first wrapper.
