Technical Description
This training system for process control represents a fully functional
process control system. It consists of four individual systems: process
module, control console, fault simulator and service module. The actual
process module contains the devices and loops for liquid-level, flow
rate, temperature and pressure control with all necessary equipment,
tanks and vessels, pipes and delay coils, various sensors and
pneumatically actuated valves. The system is laid out in a way to
represent a realistic part of a plant also found in heavy industry. The
control console is equipped with four digital universal industrial
controllers and four three-channel chart recorders. The controllers can
configured independently as required and can be operated both
individually and simultaneously. They all have serial interfaces
permitting parameters to be set from a PC and facilitating interfacing
with a process control system. The separate console for the fault
simulation unit is used to study ten different typical system faults,
e.g. sensor failure or cable break. These are activated using switches.
Their effect on the system behaviour of the system can then be
investigated. The service module provides compressed air, hot and cold
water for the process module. A process communication system
facilitates the central control and monitoring of the system.
