Abstract
Modern automation systems architectures which include several subsystems for which an adequate burden sharing is required. These subsystems must work together to fulfil the tasks imposed by the common function, given by the business purpose to be fulfilled. These subsystems or components, in order to perform these tasks, must communicate with each other, this being the critical function of the architecture of such a system. This article presents a MCIP (Monitoring and Control of the Industrial Processes) client application which allows the monitoring and control of the industrial processes and which is object-oriented. As a novelty, the paper presents the architecture of the user object, which is actually a wrapper that allows the connection to Communication Standard Interface bus, the characteristics of the IIoT (Industrial Internet of Things) object and the correspondence between a server’s address space and the address space of MCIP.
Highlights
SCADA (Supervisory Control and Data Acquisition) systems are those hardware/software systems that allow data acquisition from sensors or field devices used in the industrial process monitoring and control, and allow the transmission of command/instructions to the remote field devices or actuators [1]
The mcip.exe application has a basic set of objects to which, by loading some dynamic *.dll type libraries, one can add other objects supplied by the producer or objects can be added on demand or programmed by the user
Because the architecture of the MCIP application is based on objects and on the connections between objects, once a middleware objects is created, any other object within a project will be able to connect to it
Summary
SCADA (Supervisory Control and Data Acquisition) systems are those hardware/software systems that allow data acquisition from sensors or field devices used in the industrial process monitoring and control, and allow the transmission of command/instructions to the remote field devices or actuators [1]. The architecture must be based on the international standards for data exchange which allow data sharing from the devices placed on the hierarchical levels of the enterprises by the control and management systems of the processes. This architecture is a virtual level model which offers an overview of the underlying process level consisting of data units accessible randomly by means of a standardized and unified interface. The architecture must ensure an optimum transfer of data based on a simple but generally accepted rule that the most important data must be transferred only once at any given time To achieve this goal, the acquisition of the data contained by the process must be performed using appropriate communication technologies.
