Case studies

A Raspberry PLC reads propulsion data over Modbus, listens to NMEA 2000 and sends it to shore over MQTT, with no write path to the propulsion control.

The PDF is the content of the page in four pages. Interactive version: Naval propulsion data gateway case study online.

A certified safety controller stops the AGV and an ESP32 PLC runs lights, load sensors, charging and the battery link: signals, split and FAQ.

The PDF is the content of the page in four pages. Interactive version: AGV auxiliary I/O and safety status case study online.

AHU controller for OEMs: an M-Duino 58 runs supply air, fans, coils and dampers of every unit in a series and gives the BMS a Modbus TCP map.

The PDF is the content of the page in four pages. Interactive version: HVAC air handling unit controller case study online.

An ESP32 PLC per tracker row and a Raspberry PLC per block send every tracker to the plant SCADA over Modbus TCP, stow on wind and buffer offline.

The PDF is the content of the page in four pages. Interactive version: Solar tracker data gateway case study online.

A PLC in the pivot panel waters by sector, sets the depth with the percent timer, stops on low pressure and reports to the phone over 4G and MQTT.

The PDF is the content of the page in four pages. Interactive version: Center pivot irrigation case study online.

At Bodegas Care, an ESP32 PLC rejects uncapped bottles at 3,000 bottles an hour, tracks lots, serves a web page and sends every lot to Google Sheets.

The PDF is the content of the page in four pages. Interactive version: Bodegas Care bottling line success story online.

Case study of an automated warehouse for a company that sells beauty and personal care products online. An ESP32 PLC looks up the location of each product in the inventory and sends the orders to the mobile robots that pick them. Packing uses barcode scanners, and an ERP prints the labels, requests the collection and sends the tracking to the customer.

The PDF is the content of the page in four pages. Interactive version: e-commerce pick and pack case study online.

Success story of SI-WINE, a wine fermentation control solution by SIRA, a technology company from Andorra and a technology partner in robotics, PLCs and artificial intelligence. The software is from SIRA, and the control unit runs on Industrial Shields hardware: an M-Duino PLC that acts on the cooling and a 7-inch TouchBerry Pi panel PC. Wireless probes in each tank, limits per tank, jacket valves and alerts.

The PDF is the content of the page in four pages. Interactive version: SI-WINE wine fermentation success story online.

Success story of a research project on the grain angle of wood. A laser shows the grain, and an M-Duino 58 PLC turns the sample on a platform in steps of 3.6 degrees inside a dark chamber, takes orders from the team own image capture software and fills a data set of 9,000 images per species for 60 commercial timber species from Malaysia.

The PDF covers the challenge, the three jobs (step the platform, talk to the software, fill the data set), the system architecture and the hardware used. Interactive version: wood grain angle laser research story online.

Case study of a knitting plant with many machines from different makers on one factory WiFi. One ESP32 PLC per knitting machine reads the machine contacts through coupling relays, the speed and the shaft turns on interrupt inputs, and a three-phase power meter. It publishes the state, the alarms and the energy over MQTT, and a concentrator in each production area keeps the data until the server confirms it.

The PDF covers the challenge, the three stages (state, energy, delivery), the system architecture with the signal table and the hardware used. Interactive version: knitting machine energy monitoring case study online.

Implementation of a meat selection line controlled by an Industrial Shields arduino based PLC. It has several advantages like no personnel handling, total hygiene, high degree of accuracy in selection and perfect climatic conditions for meat.

Temperature and humidity of a warehouse must be controlled automatically and sensors will be installed throughout the area to ensure that the measurements are reliable.
