Dear Sir,

I want to fetch data from classic OPC DA Server. Can it possible by usingModbus.Net?

Thanks,

parallelbgls commented 7 years ago

Of-cause, Please download Modbus.Net and Modbus.Net.OPC at the same time. It included an OPC DA(Data access) implementation and an OPC UA implementation. The English document will be published soon I finish version 1.3.8

But remember if your OPC DA server is hosted as an administrator application, your client must be run in administrator.

Alright, I have to apologize that I have to make this project stabilize because of a huge project that need to read over 16,000 points. And I need to fix the unit test after this project. So English document would be accomplished not so soon. Opc is a little bit different from other protocols. So I have a quick way for you to understand that. Cause there is a sample da machine FBox/FBoxOpcDaMachine in Modbus.Net.OPC, and OpcTest in tests for calling. This is the quickest way for you to learn how to read OPC DA data. For Opc link address, you can download a free software called "Matrikon OPC Explorer" to get the server address.
