Remote administration of control systems

Abstract

This contribution describes a possibility of implementation of external I/O units for real time control of laboratory models. DataLab I/O is used as external I/O unit. This unit includes digital and analog input/output. Control Web 5 components (pid_controler, boolean_controler) are used for control algorithm. These algorithms are applied at the first control layer in industrial PC DataLab PC/LCD. This application communicates with superior level using RS 485 bus. Second and third control level of control are realized by Control Web 2000 system. Access from the Internet is top level of control of this laboratory task.
