Merz s.r.o.

Basic function of the information system

• Technology control - local control systems for individual technological units implemented by means of Programable Logic Controller (PLC) SAIA PCD.
  
• Communication amongst local control systems and the central dispatch by means of S-BUS network.
  
• Vizualization - i.e. graphic display of actual values of the monitored units in technological schemes.
  
• Filling - saving the acquired data in a database.
  
• Reporting – evaluating the historical data (tables, graphs, etc.).
  
• Alarms - monitoring the specified limits and the administration of the overrun reports.
  

Assets of the information system

• Fully documented and reliable control system.
  
• Savings due to higher work efficiency.
  
• Savings due to the optimizing the consumption of electrical energy.
  
• Higher level of security in individual objects and the whole control system.
  
• Available information from the control system - simple decision making based on more and mutually related information.
  
• Transparency of individual activities.
  
• Simpler inspection of the operation and employees.
  
• Improvement of the algorithms of the technological units control.
  
• Resolving the technological sequence.
  
• Above-standard servicing works.
