Application of Industrial Automatics Systems for Monitoring of Operational States of Machines

In the recent years, industrial automatics practically was used in all domains of economy. Particularly, it concerns to manufacturing processes and technological processes. It seems that in these systems, very important meaning have measuring and control devices, installed practically in all production machines. Operational parameters of machines, registered by these systems are the kind of source of very important information, which not always are utilized in proper way by the users. Particularly, it concerns mining branch, where more technically advanced machines are used. However, not always their users utilize the big potential of these machines. For this reason, in the paper there are presented results of studies, enabling the application of industrial automatic systems to analyze operation states of machines, based on registered parameters of these machines. Longwall shearer was submitted to detailed analysis as the most important machine in mining exploitation process. There are presented proposals for application registered data for determine effectiveness of its utilization and to diagnose its technical condition. Presented paper is aimed to realize and encouraging users to wider practical use of the capabilities of industrial automation systems. This should improve efficiency and safety of production processes.
