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.
