Reverse engineered a "black box" dust filtration PLC
controller. This malfunctioning device cut the plant's production by 40%-60% for
months due to environmental issues caused by dust emission.
Replaced it with a Siemens PLC, wrote the logic, and led the rest of the hardware
installation activities. Production rate returned to nominal.
-
Created a cloud based, semi-automatic PLC modification
approval system that digitizes records, validates user input, and makes the
approval process across departments transparent and convenient. Benchmarked across the
business unit.
-
Team leader for motor control center rehabilitation.
The project was implemented ahead of time, within budget, and without unforeseen incidents.
-
Restored the automatic functionality of a material stacking
system which had been out of order for many years. Simplified the programming
without reducing machine safety interlocks, and eliminated 3rd party consultation costs.
-
Program translator, project coordinator, and commissioning
engineer for a plantwide PLC upgrade. Understanding both the old and the new
system
ensured minimal errors in conversion.
Hands on involvement on the electrical modifications
across the plant during this project.
