Computer integrated manufacturing: overview of modern standards
(2016) Pupena, Alexander; Elperin, Igor; Mirkevich, Roman; Klimenko, Oleg
The article deals with modern international standards ISA-95 and ISA-88 to develop integrated automated control systems. Shown scope of standards in the context of a hierarchical model of the enterprise. Article built in such a way to describe the essence of the standards in the light of the basic descriptive models: product definition, resources, schedules and actual performance of production activities. Description of the product definition given by hierarchical presentation of products at various levels of management. Much attention is given to describe this type of resources like equipment, which is logical chain to all these standards. For example, the standard batch process control shows the relationship between the definition of product and equipment on which it is made. The article shows the hierarchy of planning ERP-MES / MOM-SCADA (in terms of standard ISA-95), which traced the decomposition of common production plans of enterprises for specific works at APCS. We consider the appointment of the actual performance of production at MES / MON considering KPI. A general scheme diagram of the relationship of activities and information flows between the functions of generalized picture shown operating on a level MES / MOM. Finished article rationale for distribution, approval and development of standards ISA-88 and ISA-95 in Ukraine. The article has an overview and can be useful to specialists in computer-integrated systems control and management of industrial enterprises, system integrators and suppliers.
Development of the framework for the controllers of the process base management system to meet the requirements for integration with other subsystems and to implement service functions and diagnostics service
(2017) Pupena, Alexander; Mirkevich, Roman; Klimenko, Oleg; Polupan, Vladimir
We consider approaches to develop a framework for application of software for programmable logic controllers as components of the base system process control (BPCS) with regard to their integration with other systems (SCADA, SIS, BPCS, MES/MOM) and increased requirements to the diagnostic process and service process and equipment. The concept of software framework is designed for controllers of PAC (Process automation controller), based on open standards IEC 61131 and is not used for producing specific solutions. The structure and the internal implementation of library elements of the frame is based on ISA-88, ISA-95, ISA-106 (Draft) ideas which provide the simplest integration of control systems into a single integrated automated control system. The paper proposes mechanisms to improve the diagnosis of the process and the system, quickly setting up the system and restore its functionality after failures. The frame is a set of interrelated elements of library functions and function blocks, which are described at their interface level, interaction principles and algorithms of functioning. It is assumed that IEC 61131-3 languages will be used for the implementation of framework for the particular controller, but it is not a prerequisite. Set of frame elements can be expanded and supplemented with additional functionality without infringing the general principles. First time proposed universal structure for process control of milk production by using modern standards for construction of integrated automated control systems.
Dynamics of changes in temperature of batch sterilizers with backpressure
(2017) Klimenko, Oleg; Petrenko, Valentin; Tregub, Victor
The article describes the construction of dynamic subsystem logical and dynamic model for batch sterilizer with counter pressure needed for the construction of programmer. To describe the dynamic of counter-pressure autoclave is used mathematical method that takes into account the sequence of the autoclave. Modeling scheme for areas of heating and shutter, and cooling area are programmed in MatLab with the heat balance equation. There are circuit modeling temperature changes in blanks in areas of heaing and shutter speed and cooling section.
