I have not posted in quite a while. I am about to wrap up a project that uses remote, wireless-communicating control panels to control the levels of six retention ponds in a municipality in Kentucky. I am in the process of testing and putting the finishing touches on the HMI. Here’s a screenshot of the overview screen:
This project was a challenge because I have not used Modbus in the last decade and I have not used AutoCAD to design a control panel in almost as long. Everything came together pretty well, except for the Scope Creep part. I have had long delays throughout the project getting information from the rep. Now that everything is done, the rate of communication has suddenly hastened and I have been given requests for new “features”. I have added the ability to enter a percentage limit for the gate valves, but features that require additional wiring have to be declined. I hope to have the six panels shipped on Friday.
