Manufacturing Execution System (MES)More and more applications in the factory, indicating that the integration of information and automation of the depth of an irreversible trend. The MES is in the execution layer between the planning level and the field, which aims to optimize the management activities,emphasis on accurate real-time data。 MES, as the main management system of enterprise manufacturing informationization, especially for large and medium-sized manufacturing enterprises, is the necessary means to enhance the efficiency of enterprises. However, because the factory has a large number of production equipment, various types of equipment, communication methods, data acquisition volume, resulting in each MES project data acquisition becomes very cumbersome. However, data acquisition is the basis of material tracking, production planning, product history maintenance and other production management, so the accuracy and real-time of information become the key to realize the success of informatization. I have done a lot of different MES projects over the years, there are large enterprises, there are small businesses, the perfect solution to each MES project data acquisition problem, the solution of these problems benefited from my years engaged in embedded software development, multi-port Communication server development, large-scale PLC control system development, intelligent control terminal development, etc. So summarizes the following points about data acquisition aspects of the implementation method: First, the PLC class: using C # or C + + Direct programming access to the PLC (do not need to spend money to buy configuration software or third-party software) Mitsubishi PLC:Q series, FX series, Omron PLC:CJ1 series, CP1 series, CJ2 series, CS1 series Siemens PLC:S7-300,S7-200 PLC: A full range of PLC: A full range of Panasonic PLC: A full range of ... There are many other brands PLC two, configuration software class: OPC server, using C # or C + + OPC access such as Siemens WINCC, Rockwell Rslinx, Configuration King, easy control configuration software, force control Three, measuring equipment: using C # or C + + direct programming access such as electronic scales, voltage tester, Instrument with communication interface, such as a battery meter. Quality Collectors: Direct programming with C # or C + + access to a workshop install up to 256 self-developed wireless quality collectors in as long as 2 seconds to collect data. Such high-speed data access to the first domestic companies to do. Five, barcode scanner or RFID Reader: direct programmatic access using C # or C + + injection molding machine class: Direct programmatic access using C # or C + +
Need to add data logger
Seven, CNC equipment class: OPC server, using C # or C + + OPC way to access
Need to add data logger
Viii. Other smart devices: direct programmatic access using C # or C + + For example, Advantech's Data Collector IX, the Japanese company's Anton System or Kanban system: direct programmatic access using C # or C + + if Toyota parts factory Anton Systems X. Third-party software: using C # or C + + Direct programmatic access to a database or CSV file or text file The above is just a list of common parts, there are many equipment systems need technical transformation to carry out data collection, not listed.
