PLC Connect makes it possible to configure System 800xA as a hybrid DCS/PLC system HMI. It enables the remote connection of controllers and PLCs in single as well as redundant systems.
PLC Connect uses of Real Time Database to store all process information before it gets presented to the operator, a benefit in particularly useful for slow or fragile connections as the database at all times keeps an image of all connected signals on the hard drive of the computer. PLC Connect supports OPC, serial and dialed communication.
The basic idea of PLC Connect is to give engineers the ability to create a logic, object-based environment in Plant Explorer independently of how the actual PLC structure looks. Collecting variables from a PLC and organizing them into object types enhances the overview and understanding of the system.
PLC Connect gives operators the same user experience for devices controlled by a PLC as for embedded 800xA DCS controllers. This experience is based on patented
Aspect Object technology, which brings real-time data, live video streams and any other type of asset information to the fingertips of personnel involved in plant operation.
800xA offers a functional building-block approach to system design for all sizes and types of process application. It enables customers to add new functions and migrate to larger configurations as their needs grow, without compromising existing investments.
This means that traditional system capabilities, typically requiring a large number of process IOs to be connected through a range of controllers from different manufacturers, can now be realized with 800xA PLC Connect.
