Thus, some devices used in the system are easily...
BAS (Building Automatic System) network structure in subway station directly determines the performance of their communications, and thereby affects the performance of workstation, OCC (Operation Control Centre), TCC (Traffic Control Centre) and other multi-monitor clients. Cyber Series software and CSC800-type PLC are adopted in this paper to structure the station BAS network structure. The network...
A PLC can communicate through its inputs and output signals with the plant. The capabilities of PLCs have developed over the years, with reliability, performance, and operational. Developing monitoring in Automation Control System is a major industrial concern since those systems are more and more complex and involved in many safety critical application fields. The Automation system is being widely...
Water treatment plants have to provide good water quality and at the same time low operational costs. Owing to various physical, chemical and biological interactions water treatment processes are often difficult to handle and reliable predictions for the course of processes are difficult to obtain. Developing monitoring in Automation Control System is a major industrial concern since those systems...
A control system for path-configurable transporting and multi-site processing line for large cargos was developed. The system can maintain the information of the cargos synchronizing with the cargos which were transported in different paths. Generic PC/PLC-based two-layered hardware architecture was adopted. Pipe and filter model was employed in the PLC control software as its architecture. Pipe and...
