Address allocation of input/output points Add the DI2/DQ2 signal board, DI8 module, and DQ8 module to the device view of CPU 1214C, and their 1. Q addresses are automatically assigned. After the configuration task is completed, you can use the device overview view to view detailed hardware configuration information. In the device overview view, you can see the byte addresses of the CPU integrated I/O points and signal modules. For example, the byte addresses of the 14 point digital input integrated with CPU 1214C are 0 and 1 (10.0 to I0.7 and I1.0-I1.5), and the byte addresses of the 10 point digital output are 0 and 1 (Q0.0 to Q0.7, Q1.0 and Q1.1). The byte addresses of both DI2/DQ2 signal boards are 4 (14.0-14.1 and Q4.0-Q4.1). The addresses of DI and DQ are allocated in bytes. If all the bits in a byte allocated to them are not used up, the remaining bits cannot be used for other purposes. From the device overview view, you can also see the input and output byte addresses of the signal modules assigned to each slot. Select a module in a slot in the device overview to modify the automatically assigned 1 and Q addresses. It is recommended to use an automatically assigned address and not modify it. However, during programming, the addresses assigned to each IO point during configuration must be used. Parameter settings for CPU integrated digital input points When configuring digital input, first select the CPU or signal board with digital input in the device view or device overview view, and then select "Properties>General>General" in the inspection window. The right window displays general information about the module, such as its model, order number, firmware version number, rack and slot number, and a brief description of the module. Select the CPU or digital input signal board, and then select a channel in the "Properties>General>Digital Input" folder of the inspection window. You can use the selection box to set the delay of the input filter (0.1 μ S-20 ms). You can also enable the rising edge interrupt, falling edge interrupt, and pulse capture functions of each channel using check boxes, as well as set the hardware interrupt organization block (OB) to be called when interrupt events are generated. The pulse capture function temporarily maintains a narrow pulse state of 1 until the next refresh of the input process image. The rising edge interrupt and falling edge interrupt can be enabled simultaneously, but the interrupt and pulse capture functions cannot be enabled simultaneously. Parameter settings for DI modules Select the digital input module in the device view, and then select "Digital Input". You can only set the delay of the input filter in groups (4 points per group) (0.2-12.8 ms) At the beginning of each scan cycle, the CPU reads the status of the external input circuits of the input module and stores them in the process image input table. During the scan cycle, the user program calculates the output values and stores them in the process image output table. At the beginning of the next scan cycle, write the content of the process image output table to the output module. Parameter settings for digital output points Firstly, select the CPU, digital output module, or signal board in the device view or device overview view. After selecting "Digital Output" in the inspection window, you can choose to keep the digital output at the previous value (keep last value) when the CPU enters STOP mode, or use an alternative value. When selecting the latter, select an output channel in the left window and set its replacement value with a check box to ensure that the system enters a safe state when automatically switching to STOP mode due to faults. A '√' in the check box indicates that the alternative value is 1, otherwise it is 0 (the default alternative value). Parameter settings for analog output module Select the 4AI/2AQ module in the device view and set the parameters for analog output. Similar to digital output, it can be set that after the CPU enters the STOP mode, each analog output point maintains the previous value or uses an alternative value. When selecting the latter, alternative values for each point should be set. The output type (voltage or current) and output range of each output point need to be set. It can activate the short circuit diagnosis function for voltage output, the open circuit diagnosis function for current output, and the overflow diagnosis function for exceeding or below the upper limit value. The parameter setting methods for the CPU integrated analog output point, analog output signal board, and analog output module are basically the same.

Programmable Logic Controller (PLC) is a device designed specifically for digital operations in industrial environments. It uses programmable memory to receive and store user instructions, which are then used to control various types of machines and processes. Due to its high reliability, high flexibility, and low power consumption, PLC has been widely used in the field of modern industrial automation. In this article, we will discuss the selection and design points of PLC, so that you can better understand how to select and design PLC systems. 1、 Selection of PLC When selecting a PLC, the following factors need to be considered: PLC specifications The specifications of PLCs are usually classified based on their input/output (I/O) points and processor speed. The number of I/O points is one of the important parameters of PLC, which determines how many input and output signals the PLC can control. The processor speed determines the processing power of the PLC, including scanning speed and execution speed. When selecting a PLC, it is necessary to choose the corresponding specifications based on actual needs. For example, if you need to control a large number of input and output signals, you need to choose a PLC with more I/O points; If you need to process a large amount of data quickly, you need to choose a PLC with a faster processor speed. Functions of PLC In addition to specifications, it is also necessary to consider the functionality of the PLC. The functions of PLC usually include logic operations, counters, timers, PID control, communication, and data processing. When selecting a PLC, it is necessary to select a PLC with corresponding functions based on actual needs. For example, if PID control is required, a PLC with PID control function needs to be selected; If communication is required, a PLC with a communication interface needs to be selected. Brand of PLC When choosing a PLC, it is also necessary to consider the brand of the PLC. Different brands of PLCs have different characteristics and user experiences. Therefore, when choosing PLC, it is necessary to choose the corresponding brand based on actual needs. 2、 Design points of PLC In the design process of PLC, the following key points need to be noted: Determine control requirements Before conducting PLC design, it is necessary to clarify the control requirements. This includes determining which machines or processes need to be controlled, which signals need to be collected, which signals need to be output, and so on. Only by clarifying the control requirements can effective PLC design be carried out. Determine the number and type of I/O points According to the control requirements, it is necessary to determine the required I/O points and types. The number of I/O points refers to the number of signals that the PLC needs to receive and output, while the type refers to whether these signals are input signals or output signals. Select the corresponding number and type of PLCs based on actual needs. Determine control logic The determination of control logic is based on control requirements and I/O points to determine the logical relationships within the PLC. This usually involves a series of control programs, including logic operations, counters, timers, etc. When determining the control logic, it is necessary to select the corresponding logic program based on actual needs. Determine communication protocol When designing a PLC, it is also necessary to determine the communication protocol. Communication protocol refers to the communication method and protocol between PLC and other devices. Select the corresponding communication protocol according to actual needs, such as Modbus, Profinet, etc. Determine programming language Finally, it is necessary to determine the programming language. Programming language is a language used to write and edit PLC programs. Different PLC brands may support different programming languages. When determining the programming language, it is necessary to choose the corresponding programming language based on actual needs. In short, the selection and design of PLC is an important link in the field of industrial automation. When designing and selecting PLC, it is necessary to choose the corresponding specifications, functions, brands, and other parameters based on actual needs. At the same time, it is also necessary to pay attention to factors such as the operating environment and lifespan of the PLC to ensure the stability and reliability of the PLC system.

The number of independent motions possessed by a component is called its degree of freedom. Obviously, a free component that performs planar motion has three degrees of freedom. A mechanism is composed of many components connected in a certain way, which should ensure that there is a certain relative motion between the components. This type of connection that allows two components to come into direct contact and generate a certain relative motion is called a motion pair. Low pair The motion pair composed of two components through surface contact is called a low pair. It includes two types: rotating pair and moving pair. The rotating pair can only rotate relatively in one plane, while the moving pair can only move along a certain axis direction. Therefore, a low pair introduces two constraints, namely reducing two degrees of freedom. Senior Officer The motion pair composed of two components in contact with each other through points or lines is called a high pair. 1. Fixed parts (rack) The components used by humans to support moving components are called fixed components (racks). The cylinder block in an internal combustion engine is a fixed component used to support pistons, crankshafts, etc. 2. Prime mover The active components with known motion patterns are called active components. The piston in an internal combustion engine is the driving component, and its motion is input from the outside world. 3. Follower The other moving components that move with the motion of the original component are the driven components. Connecting rods, crankshafts, and other components in internal combustion engines are all driven components. This type of multiple rotating pairs composed of three or more components with overlapping axes at one point is called a composite hinge. The local independent motion that does not affect the motion of the entire mechanism is called the local degree of freedom. In practical mechanisms, constraints that repeat other constraints without limiting motion are called virtual constraints. Virtual constraints should be disregarded when calculating the degree of freedom of the mechanism. If one is a crank and the other is a rocker, then this mechanism is called a crank rocker mechanism. In a hinged four bar mechanism, if both connecting rods are cranks, then this mechanism is called a double crank mechanism. In a hinged four bar mechanism, the two connecting rods are both rocker rods, which is called a double rocker mechanism machine. 1. There must be one pole between the connecting pole and the rack as the shortest pole. 2. The sum of the lengths of the shortest and longest strokes is equal to the sum of the lengths of the other two strokes. As can be seen from the above, when determining the form of a chain four bar mechanism, it is necessary to first determine whether the mechanism meets the rod length condition. If so, the form of the mechanism can be determined using the following method: ① If the short rod can be used as a connecting rod, a crank rocker mechanism can be obtained; ② If the shortest rod is a frame, a double crank mechanism is obtained 3. If the shortest rod is a connecting rod, a double rocker mechanism is obtained. A four bar linkage that satisfies the condition of being in a long chain, regardless of which member is used as the frame, does not have any curvature, so the mechanism can only be a double rich linkage. ■Speed of Reply to Inquiries  Attn: Mr. Liao Mobile: +86 15259245292 Email: postmaster@adlemanplc.com   WeChat/WhatsApp: +86 15259245292 Address: Room 1601, Building 6, Haicang Seattle, No. 330 Zhonglin Road, Haicang District, Xiamen City, Fujian Province

Seven steps to complete Siemens PLC debugging, electrical novices can learn even after reading it! Many beginners in electrical engineering may not know how to start debugging after completing the design of electrical control cabinets and PLC programs, or some may encounter issues such as PLC burning due to improper debugging methods. So, how should the designed electrical system be debugged? You can follow the following seven steps. 1. Check the circuit according to the drawing (without power supply) The drawings of a general PLC system include two parts: inside cabinet drawings and outside cabinet drawings; Cabinet drawings refer to the wiring diagrams inside the cabinet; The drawings outside the cabinet are the wiring diagrams for all electrical cabinets. What needs to be checked in this section is; 1. Is the drawing design reasonable, including the capacity of various components, etc. 2. Check whether the components are connected strictly according to the drawing. The most important thing to note during this process is to check the power supply: 1. Ensure that the circuit is not short circuited. 2. Ensure that strong and weak currents are not mixed together; Because the PLC power supply is 24V, once 220V is connected to the PLC due to wiring errors, it is easy to burn the PLC or expansion module. 2. Check the external circuit of the PLC, commonly known as "dotting" After confirming the power supply, power on and test the input and output points, commonly known as "dotting". Testing the IO points requires testing one by one, including operation buttons, emergency stop buttons, operation indicator lights, cylinders and their limit switches, etc. The specific method is to have one person operate the buttons on the site side and the other person monitor the input and output signals on the PLC; For large systems, a test table should be established, that is, marked after testing. If any wiring errors are found during the construction process, they need to be dealt with immediately. In this step, it should be noted that it is necessary to back up the program and clear the program in the PLC or disable the program to avoid device actions caused by testing. 3. Check the mechanical structure and test the motor load This step requires checking whether the mechanical structure is tight, and whether the motor load is properly protected to avoid accidents caused by accidents. After the inspection is completed, it is necessary to manually test the operation of the equipment. For example, for forward and reverse rotation motors, it is necessary to test the integrity of the circuit and conduct live testing. For frequency converters, corresponding parameters should be set and motor optimization, static identification or dynamic identification should be carried out. It should be noted here that for some special loads, such as vertically moving loads, they need to be carried out by professional personnel to avoid testing accidents caused by improper control. 4. Debugging manual mode/semi-automatic mode and related logical relationships After testing both the IO point and load side, the next step is to debug in manual mode. The manual mode here can also be called semi-automatic mode, which does not directly press the solenoid valve or contactor by hand, but refers to driving the device through buttons or HMI buttons, which corresponds to the automatic state. Manual mode testing can decompose the automatic mode according to human preferences, making it easier to test the program. The most important aspect of this process is to test the safety functions, that is, to test whether the emergency stop, safety grating, and other safety functions have played a corresponding role while the equipment is running. 5. Debugging automatic mode according to production process After completing semi-automatic debugging, the automatic work can be further debugged. This link is the most important and requires testing various interlocks according to the production process, including logical interlocks, safety interlocks, etc., and testing several more work cycles to ensure that the system can work continuously and correctly. 6. Testing of special processes In addition to logic control, there are many expanded functions in the PLC system, such as PID control. After these logic debugging are basically completed, you can start debugging analog and pulse control. The most important thing is to select appropriate control parameters. Generally speaking, this process is relatively long. Be patient and make multiple choices of parameters before selecting the best one. Some PLCs have PID parameters that can be obtained through self tuning. But this self tuning process also takes a considerable amount of time to complete. 7. Complete all the steps above The entire debugging is basically completed. Next comes the step of pre production, which is a pre production work inspection. During this stage, special tests can be carried out in conjunction with production, such as whether the production rhythm is met, whether the safety function can still function under load, etc. Generally, the work can be completed after a certain period of continuous production.   Novice should pay special attention to the power supply. I remember that when I debugged the first project many years ago, the construction company connected the 220V contact and 24V contact of the pull cord switch of the large belt incorrectly (the pull cord switch of the belt is a safety device, with two sets of contacts, one is 220V to disconnect the control loop, the other is 24V to enter the PLC), which caused the burning of a digital input template. Later, it became a long memory. When debugging again, we must distinguish 220 and 24, I never had any problems again. ■Speed of Reply to Inquiries  Attn: Mr. Liao Mobile: +86 15259245292 Email: postmaster@adlemanplc.com   WeChat/WhatsApp: +86 15259245292 Address: Room 1601, Building 6, Haicang Seattle, No. 330 Zhonglin Road, Haicang District, Xiamen City, Fujian Province

In 2023, the sports control market was worth 18.9 billion US dollars, with the largest market share in China, accounting for 37%.  July 26, 2023- The latest research by global market intelligence company Interact Analysis shows that after the high demand period for consumer products in 2021/2022 drove automation investment, the motion control market will return to stable growth. In 2022, the market value was 17.7 billion US dollars. Although the Asia Pacific region is the largest motion control market, the Americas region will show the highest growth rate in 2023, reaching 7.4%. Global economic growth will decline in 2024, but is expected to rebound in the medium to long term. In 2022, the Asia Pacific region, especially China, remains the largest motion control market, accounting for 37% of global revenue. Europe, the Middle East, and Africa account for 33% of the global market, followed by Japan and the Americas, accounting for 16% and 14% respectively. In 2023, the global motion control market value will reach 18.9 billion US dollars. However, the study by Interact Analysis found that although some suppliers are optimistic about the growth rate, with an expected growth rate of up to 20%, others are more cautious and are expected to remain flat compared to 2022. On a global scale, the Americas are expected to suffer the most severe impact. The upcoming market slowdown has seen some of the largest motion control industries, such as semiconductors and electronic machinery, perform well due to the boost from the Chip and Science Act. In the long run, the growth of the motion control market will remain stable, but as predicted by ITR Economics, it is expected to decline by 2024, consistent with the next economic downturn trend. Interest rates and high inflation will continue to affect the demand for industrial automation, and Japan's growth will experience the largest decline. From 2022 to 2027, the global motion control market will grow at a compound annual growth rate of 4.6%, from $17.7 billion to $22.2 billion. Japan's overall recovery is the strongest, with an average growth rate of 6.9% by 2027.
