Системные шины AHB разделены на APB1 (36 МГц) и APB2 (72 МГц), из которых 2 > 1 означает, что APB2 подключен к высокоскоростным устройствам 2.STM32f10x. h = reg52. h (с базовым определением битовой операции), другой - STM32f10x ref.h, который конкретно контролирует конфигурацию периферийных устройств, то есть роль файла заголовка коммутатора HSE Osc (Высокоскоростной внешний генератор) - это высокоскоростной внешний кристаллический генератор, который обычно работает на 8 МГц, в то время как HSI RC (Высокоскоро...

caseMotion control of hydraulic feed device: Left row illustration: Right row illustration: Control switch (conversion condition): Action requirements: Sequential functional diagram drawing: Ladder diagram drawing:

1、 Action analysis When a person approaches the automatic door, sensor X0 is turned on, and Y0 drives the motor to open the door at high speed. When it touches the door opening deceleration switch X1, it changes to low-speed opening. When the door opening limit switch X2 is touched, the motor stops running and starts to delay. If the sensor detects no one within 0.5 seconds, Y2 will start the motor and close the door at high speed. When encountering the door closing deceleration switch X4, switch to low-speed door closing, and when encountering the door closing limit switch X5, the motor stops running. If the sensor detects someone during the door closing period, the door will stop closing, and T1 will automatically switch to high-speed door opening after a delay of 0.5 seconds. 2、 Hardware Design Based on the previous learning and the markings in the diagram, student...

The first example of programming a material transport cart controlled by PLC 1、 Control requirements There are 6 workbenches in a certain workshop, and the feeding truck travels back and forth between workbenches to feed. Each workbench is equipped with a position switch (SQ) and a breathing button (SB). The specific control requirements are as follows: (1) The feeding truck should be able to stop at any of the six workstations at the position of the in place switch. (2) Assuming the feeding vehicle is currently suspended at workstation m (SQ m is ON), workstation n will call (SQ n is ON). If: （a） m>n ， Drive the feeding vehicle to the left until SQ n moves and stops in place. When the number of the stop position SQ of the feeding vehicle is greater than the number of the call button SB, the feeding vehicle runs to the left until it reaches the call ...

The program protection methods for S7-1500 and S7-300/400 are not exactly the same 1. Read protection In the hardware configuration, open PLC Properties - Protection to set access permissions as needed. When selecting three protection levels other than "full access permission (no protection)", an access password needs to be set. Protection level: No protection, write protection, read-write protection, fully protected (password required for upper computer communication) 2. Protection of proprietary technology for program blocks The 1500CPU program blocks, including OB, FC, and FB, all support encryption functionality. DB also supports encryption function. After encryption, the attribute is read-only, and variables can be seen, but they cannot be added or deleted. Right click on the program block that needs to be protected, click on proprietary technology protec...

1、 Module Introduction CB1241RS485 allows the S71200 CPU to connect to other Modbus devices through this module, achieving the communication function of the S71200 Modbus RTU master station. The CB1241 RS485 module also supports communication connections such as USS and point-to-point PtP. The appearance of this module is shown in the following figure. The wiring terminals and connections for the CB1241 RS485 module are as follows: 2、 Configuration Introduction This example introduces the installation of CB1241RS485 module with two CT Uni SP drivers on S71200 CPU1215DC/DC V4.0 CPU. 1. Open TIA V13 software, create a new project, specify the project name and storage path. Click on the 'Left Explorer Window' Select 'Add New Device' in the 'Add CPU Type' section. In this example, select the S71200 1215 DC/DC C...
