Abstract
The paper describes an information system applied to a newsprint machine as a functional addition to the operator’s capabilities . Examples of its use by the operators are given.
The system was designed, as part of an initial machine installation, after the intensive study of the mode of operation of two generally similar machines. The objective was to retain the skilled operator as part of the control system, but to provide him with more information more conveniently displayed to enable better and faster decisions to be made. The stored program system permits the operator to manage the machine on an information by exception basis.
The system is a Bailey 754 with alarm monitoring data display and future arithmetic capability. There are 150 analog inputs, 200 contact closures, 26 speed and draw measurements and 15 integrations. Data acquisition is continuous providing data to the parallel programmed and independently operating subsystems.
