HMI (Human Machine Interface) is the user interface in a manufacturing or process control system. It provides a graphics-based visualization of an industrial control and monitoring system. Previously called an "MMI" (man machine interface), an HMI typically resides in an office-based Windows computer that communicates with a specialized computer in the plant such as a programmable automation controller (PAC), programmable logic controller (PLC) or distributed control system (DCS).
Generally, data communication between This HMI and devices is using Modbus Protocol. But for ThingSpeak user, I changed this HMI program is to be requesting data from the API ThingSpeak.
If friends here want to try this application, please download the program here -> https://dl.dropboxusercontent.com/u/3351822/HMIforThingSpeak.rar
After download and extract files to your folder, run HINET.exe. You can change the channel that I use for this HMI, with the channel belongs to you by clicking the Configure button.
