Hi all,
I am hunting for someone who wants an HMI (Human Machine Interface) for their turbine project. I eventually want to sell small turbine control systems but first I need a little practice and work out a few kinks. You give me the modbus and IP addresses in your adruino or other controller to enterface with and I send you the HMI. This is a "free" visual basic HMI by advancedHMI so the cost to me is my time which right now I have a lot of. AdvancedHMI runs on windows without a license so you can run it on a old spare computer or buy a $100 mini PC+ windows costs and use a monitor.
My intial effort is an HMI to control a small turbine communicating with a Domore PLC simulator.
The turbine I chose was a solar saturn 750KW unit. It only uses 3 analog signals and only had 10 alarms or "Malfunctions". I had a set of electrical drawings for this turbine and wrote the Domore code to control it.
I have worked on turbine control for decades, back to the analog computer as controller days.
See the attached files for samples of the three screens I built..
Main Screen
Includes the turbine controls and enough data for the operator to make desicions. When the Malfunction indictor in the upper right turns red the operator select the alarm screen in the lower left. If he wants to understand the turbine operation he selects the trend button. This page still need a watt reading.
Alarm Screen
The alarm logic is done in the PLC. there is a current alarm window and a historical alarm window. I might put the reset button on this page too.
Trends
If the operator needs to see how the turbine has been operating he goes to this screen.
There is also a data logging function so older trends are available through excel.
PM me if you are interested.
