Normally the controllers ended up at the rear of the control area panels, and all computerized and manual control outputs were separately transmitted back to plant in the form of pneumatic or electrical alerts. Effectively this was the centralisation of many of the localised panels, with some great benefits of lowered manpower requirements and consolidated overview of the method.
However, whilst supplying a central control target, this arrangement was rigid as Each and every control loop experienced its personal controller hardware so system alterations expected reconfiguration of signals by re-piping or re-wiring. Additionally, it needed continual operator movement inside a big control space as a way to keep track of the whole course of action. With the coming of electronic processors, higher-speed Digital signalling networks and electronic graphic shows it grew to become feasible to interchange these discrete controllers with Pc-primarily based algorithms, hosted over a network of enter/output racks with their very own control processors.
