PLC Programmable Logic Controller Basics-EEWORLD

Collect

PLC is a programmable logic controller that uses a type of programmable memory to store programs, execute user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input/output. Today, I have compiled a complete collection of PLC basics for everyone to learn and share!

Analysis of simple start-stop and self-locking circuits in PLC programming

When programming PLC programs, no matter you are a novice or an experienced programmer, you will make the following low-level mistakes. Because this error is non-grammatical, the error cannot be detected by programming software. Once this error occurs, it is sometimes difficult to find it yourself. It is not until t

S7-1200PLC motion control case introduction

In this case, we mainly learn the motion control function of 1200PLC. We use this three-axis device (as shown in Figure 1) to draw a square with a length and width of 50mm. On the HMI (as shown in Figure 2), you can manually enable the axis, manually run the X-axis in the positive and negative directions,

PLC lithium battery replacement time and steps

The random access memory (RAM) that stores user programs in the PLC, counters, and auxiliary relays with retention functions are all protected by lithium batteries. The life of lithium batteries is about 5 years. When the voltage of the lithium battery gradually decreases to a certain level, the battery voltage redu

Analysis of common steps in PLC debugging

Debugging is the key work to check whether the PLC control system can meet the control requirements. It is an objective and comprehensive evaluation of the system performance. Before the system is put into use, it must be strictly debugged for all system functions until it meets the requirements and is signed and co

Features of PLC programming language

Compared with general computer languages, the programming language of PLC has obvious characteristics. It is different from high-level languages and general assembly languages. It must be easy to write and easy to debug. At present, there is no programming language that is compatible with products from all manufac

What does PLC mainly consist of?

PLC is mainly composed of CPU module, input module, output module and programmer (see Figure 1). Some PLCs can also be equipped with special function modules to complete certain special tasks. 1. CPU module The CPU module is mainly composed of a microprocessor (CPU chip) and memory. In the PLC control syst
