Types of variables used in Huichuan PLC programming In Huichuan PLC programming, the variety of variables is quite rich. Similar to other brands of PLCs, it generally includes soft components, custom variables, and system variables. Soft components typically include: bit soft components X/Y/M/S/B, and sub soft components D/R/W. It is not difficult to see that … Read more
In Huichuan PLC programming, variables often include arrays and structures. Today, I will share the usage of both. After reading, you will surely feel a sense of familiarity. Array Variables When defining custom variables in Huichuan PLC programming, arrays are frequently used, with the data type being ARRAY. First, open the variable table, enter a … Read more
⭐Advanced C Language Pointers: Truly Connecting Functions and Structures with Pointers (Highly Practical) Author: IoT Smart Academy In the previous articles, we have clarified three things: <span>&a</span> is the “address” of the variable. A pointer is a “variable that stores the address”: <span>int *p</span> Using <span>*p</span> allows us to find the original variable through its … Read more
For the C language, the supportedcustom structure typesmainly include structures (struct), enumerations (enum), and unions (union). Among these three types, structures are data formats that encapsulate data objects with related functionalities, serving as an important means to achieve code modularization and are the most commonly used data types. Enumerations name ordinary constants, making the code … Read more
