A typical application is a PID controller fed by a flow meter and using a control valve as the final control element. The DCS sends the setpoint required by the process to the controller which instructs a valve to operate so that the process reaches and stays at the desired setpoint. (see 4–20 mA schematic for example).
Digital Combat Simulator (DCS) is a combat flight simulation game developed primarily by Eagle Dynamics and The Fighter Collection. Several labels are used when referring to the DCS line of simulation products: DCS World , Modules , and Campaigns .
Common applications of OTS systems are the following: New control room operator training (e.g., start-up, shutdown, and emergency procedures) Existing control room operator refresher training (e.g., start-up, shutdown, and emergency procedures) Platform for advanced process control (APC) and optimization; Validating DCS control and logic checkout
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control.Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
Supervisory control computers are often not hardened or fault-tolerant, but they bring a higher level of computational capability to the control system, to host valuable, but not critical, advanced control applications. Advanced controls may reside in either the DCS or the supervisory computer, depending on the application.
If necessary, periodically executed applications can be implemented by using the E_CYCLE function block for the generation of periodic events as described in Annex A of IEC 61499-1. IEC 61499 enables an application-centric design, in which one or more applications, defined by networks of interconnected function blocks, are created for the whole ...
DCS devices can be used for "grooming" telecommunications traffic, switching traffic from one circuit to another in the event of a network failure, supporting automated provisioning, and other applications. Having a DCS in a circuit-switched network provides important flexibility that can otherwise only be obtained at higher cost using manual ...
As a general guide, applications which are controlled and monitored by programmable logic controllers (PLCs) tend towards PROFIBUS, and applications which are controlled and monitored by a digital/distributed control system (DCS) tend towards Foundation Fieldbus. PROFIBUS technology is made available through Profibus International with ...
