MES is deeply integrated with SAP, including exchange data about orders, warehouses, and production results.
Overall Equipment Effectiveness (OEE) Monitoring System | Poland
The project centered around a complete industrial solution monitoring the effectiveness of the machines, including the overall equipment effectiveness (OEE) and other key performance indicators. It keeps track of all the machines, continuously checking the status, the number of produced details, scraps, and alarms. Processed data is then presented to plant workers as a web application.
Machine Traceability System | Poland
A system for tracing all machine parameters, such as test results, setpoints, component information, etc. It stores all historical data and provides a dashboard to analyze such data. Integration happens via the PLC network.
NESESER | Computer Network Monitoring System | Poland
NESESER is a monitoring system that helps internet-service providers manage their networks. It connects to routers, manages switches via different protocols, and checks the device's health, status, and other vital parameters. The web application presents a real-time overview of the network, charts, and a network topology map.
Distributed Quality Control and Measurement System | Poland
This project is centered around an industrial system that enables plant workers to gather all quality control-related parameters and measurements. It is connected with physical measuring devices, so all of the results are automatically captured. It is also integrated with higher levels systems like SAP to provide all of the information concerning orders, details history, and other essential pieces of data.
Vision System Client Application for Quality Control | Poland
