What technology stack was the MES system built on? Describe the architecture.

MES (Manufacturing Execution System) is a system for managing manufacturing processes at the shop floor level. The technological stack and architecture of MES systems can vary greatly, but typically include the following components:

• Technological stack:

  • Backend: often use Java, .NET, or C++ for reliability and integration with equipment.
  • Database: relational DBMS (Oracle, MS SQL, PostgreSQL) for storing production data.
  • Frontend: web interfaces on Angular, React, or specialized desktop applications.
  • Industrial protocols: OPC UA, Modbus, MQTT for communication with equipment.

• Architecture:

  • Equipment level: sensors, controllers, machines.
  • Integration level: gateways and adapters for collecting data from equipment.
  • MES level: business logic, order management, scheduling, status tracking.
  • Visualization level: user interfaces for operators and managers.

MES systems are usually built on a multi-layer architecture with clear separation of responsibilities, allowing for scaling and integration with ERP and SCADA systems.
