Overview of Programmable Logic Controller Selection Methods
The necessity of automating the landing areas of the falling trunks of the Bereznikovsky potash mine, intended for landing people in the crate for the purpose of lowering and lifting along the shaft of the mine, is presented. The implementation of the automation procedure is based on the selection of a programmable logic controller that is suitable for these operating conditions. To this end, the main selection methods were identified: the additive method based on the involvement of experts and a subject-oriented approach. The main characteristics of the required controller and options for alternatives to programmable logic controllers among the leaders of the modern market are also determined. An experiment was conducted to compare the effectiveness of these methods of choice, as a result of which it was proved that the subject-oriented approach is more attractive from the standpoint of time costs.
