I made a poc for a company that wanted to replace the way they programmed their pick and place robots that were powered by… Excel.
( the excel made an connection to the plc and wrote the data. It took 30+ minutes, while the poc took less than 3s xD )
Sadly, it was just a proof of concept, writing random bits the size of the actual data to the plc. We swore it would result with the project being assigned to our company, but the other company’s project manager quit soon after and we lost all contact with the company… :(
