1. Used for Switch Control PLC has a strong capability to control switch signals. The number of controlled input and output points can range from a few dozen to several hundred, or even thousands, and it can control tens of thousands of points. As it can connect to virtually unlimited points, the logic problems it … Read more
PLC Programming Algorithm (1) In PLCs, there are three main quantities:Switching Quantity, Analog Quantity, Pulse Quantity. Once you understand the relationship between these three, you will master PLCs proficiently. 1. Switching Quantity also known as logical quantity, refers to two possible values, 0 or 1, ON or OFF (Switching quantities only have two states 0/1, … Read more
