I am new to PLC Programming.
I am looking to connect AB Micrologix 1200 on Ethernet Network for Point Discovery through Software.
Port 0 is connected to Preprogrammed HMI and operating on Modbus RTU.
I want to use 1761-NET-AIC Card for this purpose, But I am confused how I should connect PLC with this card when already HMI is connected to PLC on Port 0.
The ultimate goal is to acquire real time data and store in DB.
I plan to use Python/C# to acquire the data once I am clear on hardware connecting.
Please Guide.
