    We have two energy meters supplying Modbus data. We want to capture the data from 6 data points : date, time, flow, temperature in, temperature out and electricity used and then provide a real time dashboard of information and energy calculations from the data. I would like this dashboard to be on a windows application but also allow the information to be supplied to a company wide Scada system. The information should have a feature to allow us to select the data from different time periods. eg daily, monthly annually as well as the real time information. The calculations will be simple formulas to allow the data analysis to be presented on the desktop. Outputs required on desktop: Time period Total flow Weighted average temperature in Maximum temperature out Temperature delta KW of en...

As it is an industrial setup, we need keypads that will ensure rugged usage. None of these panels will be connected to any of the machines in the industry. We just need this for data tracking of our products. So the user will just input the production data and that data needs to be saved some format.

    An automatic Braking system is an intelligent mechatronic system includes an Ultrasonic wave emitter provided on the front portion of a car producing and emitting Ultrasonic waves. An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

Maybe this can be done with modbus or something.
