In today's DCS we can find different topologies (arrays of switches and their connections), thus providing greater reliability, security and robustness in the network
A high-speed network or control network in a DCS consists of all the means necessary to propagate information from/to the processors to/from each of the stations
Distributed control systems include, among other components, workstations (operation and engineering), controllers, I/O cards, I/O buses, a high-speed control network, and technology of
With the advent of DCSs, many of the problems of their predecessors (DDCs or Direct Digital Control) were solved. For starters, DCSs distributed signals much more effectively.
All parts of a control system are generally installed and assembled in cabinets, although sometimes part of it may be wall-mounted. The cabinet to be used
The installation and commissioning of a distributed control system impacts the cost and implementation schedule of a new plant or an expansion for an existing plant.
Today, the existence and application of control strategies where the controller is loaded with the process model and can therefore compare is nothing new.
