Introduction
CMCS which is call Central Monitoring and Control System. It is a system that allows operators to check the operational status and control the system or individual device manually by predefined program. It can be placed in any places which just only need to have the network covered. Operators can then just stay at a place to check and control the whole system.

Technology
CMCS includes Sensors and Electromechanical Devices, Remote Terminal Units (RTUs), Communication Links, and Central Computers. Sensors and electromechanical devices are connected to RTUs to provide various operational and status data inputs. RTUs also are the role to control the equipments or devices. Central computers are responsible for monitoring the data or status which reported from RTUs. It is also able to send control commands to be executed by the RTUs. Communication links between RTUs, and between central computers and RTUs, provide data linkage to allow the components talk to each other. The links can be wired lines or wireless communication.

Features

• Graphical interface
  CMCS provides user-friendly graphical interface for displaying the dynamic/static graphs, data, curves, flow diagrams, configuration graph of detected points.
  

• System Management
  Operator can manage the whole system easily. Different parameter settings, schedules or operation configuration can be assigned from central computer. Diagnostic of whole system also provides operators to easy understanding the health status of system.
  

• Data Logging and Reporting
  CMCS can also do the data logging to record critical data for reporting and analysis. It can associate with printer, email, pager, etc., to provide real time reporting monitored parameters or alarms.
  

• Alarm Handling
  Any alarm or fault can be displayed graphics or text through monitoring display or mobile devices. It can provide detail information of alarm, such as types, locations, time, etc., for operator taking action to solve problem or clear the alarms.
  

• Wide Range Remote Operation
  Operator can remotely control field devices through CMCS. The remote operation can be done wherever which the communication network covered. It reduces time and manpower to go the field area for controlling the devices.
