Process Control System ME 8012
Increased reliability of electricity distribution supply networks is primarily achieved by improving the performance of the automation systems used in such installations. Emphasis is put not only on the quality of the automation functions but also on the efficiency of operator control facilities that ensure fast and direct operator access to the plant. Such high demands can only be met by an automation system of distributed architecture.
The ME 8012 process control system has all the features and facilities to fulfil this specification. The ME 8012 process control system is used at all levels of automation within a supply utility plant:
- System control level
- Data transmission level
- Subordinate control levels
- Terminal control level
- Field control level
Distributed Architecture
The decentralized design of the ME 8012 station control system allows the automation facilities to be optimally matched to the process requirements. The system is of modular structure and can be applied in a centralized or distributed arrangement. The system’s intelligence is divided into independent hardware and function components, i.e. the ME 8012 subscribers. Subscribers communicate with each other through the redundant SUB-NET serial system bus.
Each subscriber processes a self-contained function within the overall automation task. Each subscriber is adapted to its part of the process by means of binary, analog and serial input and output modules, and by means of multiprocessor modules. Functionality is determined by the function macros defined during project design. The process information and the computed results are sent to other subscribers through the SUB-NET system bus. This distributed architecture of the ME 8012 control system offers significant benefits in comparison to conventional automation equipment.
