Networking of Industrial Controllers- Engineering Lab Training Systems

Technical Description  One of the aims of process automation is to monitor and control plant or plant components centrally from a computer. This task performed by a process control system. This trainer demonstrates the operation of a process control system based on a simple application. The trainer consists of two process controllers interconnected via a field bus interface (Profibus DP) and an interface card with a PC. On the PC, an OPC (OLE for Process Control) server makes the controller data available to other programs under Windows for further processing. The process control software developed by GUNT on the basis of LabView accesses the process data on the controllers and enables it to be visualised. The software also allows the process controllers' parameters to be set. Various functions such as recorders and alarm logs enable a simple control room function to be simulated.  Two potentiometers permit the simulation of input signals for the controllers. The controlled variable, manipulating variable and reference variable data are delivered as standard signals at lab jacks, enabling the controllers to be integrated into real processes at any time. Clearly structured instructional material outlines the fundamentals and provides a step-by-step guide through the exercises.
