Анализ сред разработки для работы с PLC

Abstract

Nowadays the use of programmable logic controllers (PLC) is urgent in many areas. The programmable logic controller (Programmable Logic Controller, PLC) is an electronic element of the industrial controller - a device, that helps to automate the engineering process. The programmable logic controllers (PLC) are designed , first of all, as a replacement relay-contact control schemes, which are assembled from the certain components (timers, counters, relays etc). All algorithms PLC are implemented using the programming - this is the main difference between such controller and relay control schemes. Note, that the reliability of the PLC scheme does not depend on the extent of its complexity.
