When we talk of process control it has several uses in automated systems and environments like factories. Here free SCADA and different variants of the system help to run the different processes. In process control, it monitors the sensors and adjusts to different variables. The technology might manage some complex operations, which are set up with a certain outcome as an objective. There are different kinds of process control systems that come with varying capabilities.
Single loop systems
The simplest form of automation is the single loop system of process control. In this kind of SCADA free system basic controllers are used for activation and deactivation of the processes. This is done in a predictable and linear manner. Electronic relays are an example of such systems. Process control allows a part to move through different stages of an assembly line production process in a certain sequence. Here the variations are few. Hence, when you have a simple cycle of sequences to be performed, you will be able to make use of the single loop system of a free SCADA software.
Sequence controllers
The other class of process control systems is the sequence controllers. These allow an automated cycle to be run in a redirected or adjusted manner. An instance of this type of SCADA free software is programmable logic controllers. These are devices that can monitor different sensors and trigger off different operation sequences. For instance, if a product is turning out defective, this kind of a system should be able to sense that and re route it through the assembly line to inspection areas.
Distributed control systems
These are advanced or sophisticated forms of SCADA systems. These can be used when complicated processes need to be controlled through automation. A sequence controller is able to make changes to a sequence in a certain stage, but a distributed control system allows monitoring and control at different points of a process. For that reason when an assembly line needs to be stopped or restarted or redirect the products to different locations this type of system is implemented. One can even vary the speed of an assembly line production with the help of DCS. There are different variables that can be adjusted and improved through this system.
The control factor
These systems allow monitoring of data and processes from the simple to the complex levels. SCADA systems are used in large factories as well and the systems are manned through a central control room. Usually operations are run as per a schedule. Some systems have a diagnostic sequence fed in to check the different points of the system and to ensure that nothing has gone wrong. This helps to inspect the different machines used as well as ensure that no malfunctioning occurs.
