ITW HARTNESS (Controls Intern)

My main project for this summer (summer of 2021) was to create the standard template HMI and Logic for an accumulator with siemens controllers. The responsibilities I had with this assignment were to forge a functioning TIA portal project and make it looks as identical to their current Rockwell standard as “Siemen” -ly possible. That meant starting from scratch to create said project for the current machine bit by bit, button by button.

By the time I left, I had created a dynamically changing HMI dependent on configuration options, and Derived Logic that incorporates Siemens PackML (LPML) and Event Handler Standards (TR88). I was also able to test my code on the FC280 Danfoss VFDs to assure proper communication, scaling, monitoring, and overall functionality. It is safe to say there is a clear indication that what I created is a direct descendant of the current Rockwell logic and HMI standard used on the majority of ITW`s domestic accumulation products.

I would like to note there are existing projects from previous siemens machines that could be used but they are not consistent. It takes an extended period for the controls engineer to adjust project to project because of the different software/look, and the difficulty to troubleshoot due to lack of readability/adjustment periods. You can code the microcontroller in a toaster a million different ways so if you can create a standard structure and naming convention across platforms the easier it will be for all controls engineers to get the product out the door bug-free.

Moreover, I can not emphasize enough how much I valued this internship…. I was able to get proficient skills in HMI Design in TIA portal, Countless hours of controls programming experience (I essentially programmed an entire industrial machine, I can not think of a better way to learn). Witnessed an established standard in controls, experienced 80/20. I even got the validity I hoped for when I turned down to return to GM so I can experience a brand new industry/work environment. In addition to my main project, I got to work on some Auto CAD electrical/mechanical schematics and technical drawings which strengthened my CAD skills even further (Those examples can not be shown for obvious reasons). Lastly, I must note that I found out South Carolina is a beautiful place with terrible drivers.

Here are some depictions of my work:
