MES system, or Manufacturing Execution System, is a management information system for the shop floor, which aims to optimize the management of the whole process from order placement to product completion through information transmission.
MES can provide enterprises with management modules including manufacturing data management, planning and scheduling management, production scheduling management, inventory management, quality management, human resource management, work center/equipment management, tool and tooling management, procurement management, cost management, project kanban management, production process control, underlying data integration analysis, and upper-level data integration and decomposition, so as to create a solid, reliable, comprehensive and feasible manufacturing collaborative management platform for enterprises.
Many medium and large manufacturers are using MES systems, after using MES systems, is it still necessary to use SCADA systems? What's the point of using it? This article will introduce you to it.
SCADA in the factory automation system, located between PLC and MES, SCADA can collect the underlying data, analyze, process, display, store, transmit, etc., its interfaces are numerous, fast, and the collected data can be transmitted to the MES system.
There are three main ways for enterprises to organize and manage the e-system, including MRPII/ERP, SCADA/HMI and MES. MRPII/ERP is to use material requirements planning or resource planning for production management, SCADA/HMI is to monitor production management, MES is to connect automation equipment, and integrate the information of each mining point for data analysis and management, among which SCADA because of the high degree of professionalism, plus MES also has data capture function, most enterprises have not included this in the e-planning in the past, but consider ERP and MES two architectures.
However, comparing SCADA and MES two systems, SCADA in data acquisition and monitoring of the powerful efficiency, after all, not MES can be fully replaced, and in terms of functional orientation, the main role of MES is still in management, in the data flow of the automation platform, SCADA is the data provider, and MES is the recipient, SCADA will capture the data from the PLC, and send it to MES, MES and then together with other information, analyze the meaning of the data, and provide it to the manager.
Therefore, SCADA system is very necessary in the automated production line, in the automated production line, various equipment, sensors, PLC, interfaces are numerous, many equipment can not transmit data to the MES system, SCADA system has played its professional skills, and its further analysis, screening, visualization of data has also provided assistance for the staff.
In addition, many small and medium-sized enterprises do not use the MES system, and at this time, they can also use the SCADA system to carry out automated and intelligent industrial upgrading, providing assistance for the overall management of the production line.
