ECO System



What is ECO?

ECO is short for Expert Control Operator and is the new name of the SIT control system. Expert Control (System) is a type of intelligent control system which can emulate the reasoning procedures of a human expert in order to generate the necessary control action. Expert control systems seek to incorporate knowledge about control system design, practical operations, and abnormal system recovery plans to automate tasks normally performed by experienced control engineers. SIT's ECO is the operator of this superior control system. On top of this nominal meaning, ECO also contains another meaning;
ECO is pronounced the same way as 'echo,' the sound due to reflection or imitation of another. One of the greatest design features of SIT's control system is the redundancy on all key elements on the target system. This strict redundancy design policy provides the superior stability on all FA (Factory Automation) systems where stability is the top priority. Echo exists when there is a companion, and the primary and secondary units are the partners responding to each other's request with echoing. SIT's ECO system contains the meaning and belief that the most stable control system realizes when the primary and secondary units are working in perfect harmony.

ECO System

SIT's ECO System is a set of Microsoft Windows Version 2000 (or above) applications including the operator interfaces developed on top of the FactoryLink FA ( Factory Automation) platform and other technology by SIT Engineering Co., Ltd. (http://sithome.com) ECO consists of three major components: ECO Server, ECO Client, and ECO Viewer applications.
  • ECO Server is the HMI server application which contains all the functions and drivers controlling the PLC (Programmable Logic Controller) and other instruments connected.
  • ECO Client contains the intuitive GUI (Graphic User Interface) and allows the operator to monitor and interact with the local instruments through ECO server.
  • ECO Viewer applications are dedicated data viewer applications providing operator in depth perspectives on the historical log andreal-time data.
With ECO, operator can communicate with multiple networked PLC processors and collect and display data using different strategies in real-time. By adapting Oracle database on the system for storing present (sensor) values and operation history, ECO ensures a robust and efficient data collection and analysis processes.

ECO provides the following features and services:
  • One-stop FA control system panel for servers and terminals,
  • Simple and unified UI encapsulating the complexity of operating the sophisticated control system while providing all possible controls for system fine-tuning,
  • The event data logging feature for tracking operation history,
  • The interface letting an operator to control system in real-time,
  • A robust periodic reporting system,
  • Dedicated viewer applications for specialized log data analysis,
  • Data acquisition from the factory floor through the communication network,
  • Maximizes the efficiency of the FA system operation,
  • Analyzes raw data into readable engineering data by scaling, and
  • Checks the alarm status by comparing presetting limit values for each alarm level
