ABB’s flexible and modular approach allows splitting a complex system into different tasks, such as central controls for production and for storage handling or automatic control and manual operator control desks. The data can be shared in real-time from machines to different central PLC controllers.
Furthermore, ABB’s solution uses communication modules as add-ons for process and safety data exchange, thereby being able to flexibly modify existing systems via an extension for controller and/or device. With distributed control, where data flows from one system to another, the control logic is spread across the facility, which enhances the overall system performance. The new control approach allows optimizing such systems to have all needed control and safety data available at a given time.
These new PLC modules target system integrators that are building complex installations, yet demand flexible control systems in all kinds of industrial applications. Typical applications include remote control of machines and equipment in harbors, airports, distribution centers and production facilities. Often in such industries, the control system is altered or updated to allow for production changes or extensions to the facilities. During such upgrades or maintenance, it is important that the central control systems are available. These could be manual locations with remote control access for unexpected occurences.
