There is a big industrial washing machine in the hotel which had a very old technology in the controlling area and there was a very small LCD display to see some features.
Objective: Our main job was to modify and renovate the controlling unit of the machine, because the old unit was not working and also the operator asked for better washing techniques. So we changed the AC Drive which was faulty with a new one and we replaced the controlling unit(Microcontroller) with a PLC (with few modifications in the logic). We also installed an HMI for better visualization, supervision and interaction. We did all the programming, calibrations and commissioning including wiring and building panels.
