MQModBus is an open-source project I started to connect with Modbus devices on an Android phone. It was derived from the original source of QModBus using the libmodbus libraries. This video was taken in the design stage between v0.1 and v0.2. It is completely functional in this state with no known bugs. The differences between v0.1 and v0.2 stages are feature and UI improvements. At the end of the video is a demonstration of a very basic HMI screen. It shows the capabilities of coding the PLC address directly into the code followed by assigning coil addresses and values directly to controls. This makes any device to which Qt has been ported capable of being a remote control for anything connected to a PLC.
