It is important to understand how data flows between AOIs since we have been using them extensively and there are some tricky caveats that can make programming or debugging more difficult. The misleading names of “External Access” and “Local” probably explains why there is inconsistent behavior on the “External Access” Read more…
Maintaining a complete list of alarms on both the PLC and HMI can be tedious and inaccurate to such an extent that when it’s time to crunch, alarms get missed that really should be created in code and added to the HMI. This difficulty can cause “ghost” faults in the Read more…
Developed an in-browser web application that takes DWG and DXF files and converts them into files that can be imported into Allen Bradley RSLogix 5000 / Studio 5000. The generated aliases point to hardware points in the correct format for their respective modules. The resulting code will then have information Read more…
I was responsible for maintaining the library of current code to be used in new systems while developing innovative new features and programming and installing new equipment for customers. New Features Developed I personally developed many of the most innovative new features, several of which were featured in marketing communications Read more…
Created a web HMI using no proprietary software that communicates with an Allen Bradley PLC system and an Oracle database to display complex part gauging and data and relay part data between the plant database and the PLC. The HMI application was written in React JS, communicated with a Node.JS Read more…
This is a system that I programmed and installed and also recorded, edited, and narrated the video for. I programmed the PLC and HMI for this system that loads a FANUC ROBODRILL that had been previously manually tended while controlling a retrofitted spurr on an existing conveyor line. Installation required Read more…
Matrix has built a lot of unique deburr systems, so it’s important to distinguish each one. I programmed the Siemens drives, PLC, and HMI, which includes the control of the conveyor, and its RFIDs, and the robot.
This is a relatively simple system, so the video is much shorter than others. However, it’s important to show that options exist beyond just making new systems. I taught the Fanuc robot and reprogrammed the PLC in the machine to add an interface for the retrofitted automation.
This one is kind of funny. It was recorded on an iPhone 6S propped up on top of a section 4×4 wood without any consideration that it would ever be edited together. So the video is an exercise in making the most out of limited footage. I actually programmed the Read more…
I worked with another graduate student in mechanical engineering at NIU on a project to replace the controller of an old CRS robot. Each joint was controlled by an arduino, and the arduino’s were coordinated by a computer. The computer ran a python program which went joint position commands to Read more…
