Industrial Automatic Control Systems and Controllers Annotation << Back The Possibilities of Creating Local Self-checking PLC Responsible Use Using Network Technology SpaceWire V.N. Rusanov, S.V. Kulikov Complex and important process control causes the necessity to improve programmable logic controllers (PLC). Application of PLC produced by foreign companies allowed solution of process automation problems, however, the situation taking place in the market as a result of imposing sanctions on import equipment delivery requires accelerated solutions for creating domestic PLC. At present home electronics manufacturing industry produces various types of multi-core microprocessors. Their use jointly with new technical solutions referred to the structural arrangement will enable to create domestic PLC exceeding those imported from the point of view of reliability, failure resistance, power consumption at low cost. Keywords: programmable logic controller; microprocessor; domestic component basis; failure-resistance; redundancy unit; diagnostic task; network architecture.
