AS industrial monitor and control systems grow in both size and sophistication, the demands placed upon the man‐machine interface (MMI) increase to the point at which there are significant advantages to be gained from separating the data distribution and display function from the rest of the system. One of the main benefits of such an approach is the elimination of ‘knock‐on’ effects from changes in the way the data is distributed, manipulated and displayed. In a system where data distribution and display are an integral part of the total monitor and control system, changes to one part of the system can result in unexpected and far reaching effects on the whole system. As a result, changes which would improve the MMI aspects of the system are often not implemented.
