4 level elevator project - elevator control system project | Lesson 21

Added: 2026-05-18

[00:00:00]foreign of this video is designing and implementing a simple four fellow elevator with thematic step 7. first the project will be defined in details then I'll explain my Hardware finally I'll implement the project and experience its program codes okay let me Define the four fellow elevator project this figure displays a practical view of my elevator system which must be controlled by eplc the cabin is moved by a motor in two directions of and Dot when the PLC is on for the first time the cabin should be moved to the first fellow the first sensor can detect whether the cabin had switched the first value or not after that the elevatorial system can be used and if any push button is passed the cabin will go to the selected fellow wait five seconds and then if there is another request the cabin will go to another fellow note that to update the cabinet's position the second sensor can be used it produces a pulse by passing from each fellow for example when the cabin moves upwards each part of this sensor means the current position of the cabin has increased one fellow also for LEDs were used to indicate the current position of the capping and these two tables illustrate all the input output vertices of my PLC which will be used in this project all right let's start a video by launching somatic manager software as you know using the result window in your project can be created by selecting its CPU model prefer language project name and finally I need to click on finish but let me click on cancel to create my project manually okay semantic manager how to paint my last project it's my final four fellow elevator project before to explain it let me create a new project manually to explain how the PLC can be configured by cinematic manager well let me write a name for the new project and then click on OK as you see there is not any PLC I'm going to use the somatic S7 300 CPU so I need to add thematic 300 extension to my project after that I need to Define my Hardware so I double click on the hardware icon where inside the open head window on the right side under the semantic is 300 I can find and add my equipment first I need a simple deck as you see 11 modules can be added to a standard track the first cell determines power supply type because I'm not using any of these other supplies of the men's company let me leave the first app it doesn't matter the type of of a supply to generate system data inside the second row I have to specify my CPU model I'm using a version of CPU 315 to DB okay let's continue that is how it's used to determine the type of interface module this module is used to extend out a 1700 station but I don't have it so let's go to the next graphs then from the first half I should specify other modules which were necessarily beside my CPU I'm using two digital inputs one analog outputs and then two digital outputs and finally one analog input let me find and add them to the inserted tab as you see based on a simple rule schematic manager has assigned these addresses to the inserted signal modules in this project I prefer to change the default addresses related to these two digital output modules okay let's continue to add my last module that's an analog input module on height I'll configured my Hardware now let me click on the save icon as you see my CPU has been added to my project as you know these pillock ob1 can be used to write my program note that the hardware information must be downloaded as well as the PLC project so let me open the hardware configuration window and then click on this icon to generate system data inside my project now after specifying my Hardware let me start the programming step first let me add will be 100 this product is executed only once exactly after the PLC is turned up where after will be hunted my CPU will execute ob1 continuously as the main product now let me add the function it will include the main part of my program to control the elevator system it will be called by obiva okay I want to use Obi-Wan Obi Hunter and if you want to write my book here now let's continue the video with the final project it includes my final program and Hardware information so let me close this window okay as I mentioned before this is my final project which includes my final program and Hardware settings first let me check the connection between my PLC and computer so let's select set PG and PC interface under the options menu where I'm using API Port of my PLC so I need to select PC adapter MPI now if I click on the accessible nodes icon I can see that my PLC is connected to my computer using its MPI port now let's download the whole project on my PLC before that let me see the CPU using its mini switch how high the project has been loaded on my PLC successfully now let's test it and also experience its work here as I mentioned before first my CPU will execute this product ob100 once time when it's turned on so let me open it there is on the program my CPU will reset these memories which were used inside for B1 and fc1 I'll explain it forecast later also if the first sensor is inactive this address Q 0.7 will be enabled at the beginning to move the cabin to the first fellow now let me enable the monitoring option and then run my PLC to see its performance note that instead of these two sensors I'll use these two switches as you see because the first sensor is inactive my PLC has enabled this output q0.7 to move the cabin to the first value remember OB hundred is executed only one step after that PLC executes obi-1 continuously so let me open ob1 as you see here I have three networks right now the cabin is moving down and when it reaches the first fellow the first sensor will be enabled this sensor has three task first it moves number one to this memory then stops the cabin and finally enables a bit of memory to indicate the elevatory system is ready to be used note that this memory includes 16 bits and only the first four bits will be used in this project to indicate the current position of the cabin also this bit memory has been used in the test Network to call fc1 it includes my main program to control the elevator system for example it uses these four LEDs to indicate the cabin position right now the cabin is located at the first value now let's open the function unhide my function includes seven networks the first one uses four Sr instructions to install any request form therefore push buttons on these four bits of memory note that these four bits have been used to indicate the cabin's position naturally when the cabin is located at the first value the first push button cannot set this bit of memory but if IPS the other two push buttons for example the first one the related bit will be changed to two note that every time the cabin is the fourth fellow the storage decrease on M 0.3 will be reset automatically right now the cabin is located at the first value and my PLC has enabled Q 0.6 to move up the cabin to the first fellow now let's go to the second Network remember these four bits on this address determine the cabin's position by receiving each part from the second sensor if the cabin is moving up these four bits will be shifted to the left side and if the cabin is moving down the four bits will be shifted to the right side inside an X Network I've used them to enable these four digital outputs which are connected to these four LEDs right now the cabin is moving up and by passing from each fellow this sensor produces a pass let me use that as you can see the cabin position is increasing by receiving each pulse from the second sensor now the cabin has reached their first value and my PLC has stopped a cabin let's continue the next two networks determine the cabin must be moved up or down based on the current position and the storage equates on these memories which will Define it in the first Network now the cabin is located at the force fell off if I pass the first second or third push button the cabin will need to be moved down let me Place only the second push button as you see now based on this memory the cabin needs to be moved up now let me explain the last two networks with similar program codes Network system on Q 0.6 to move up the cabin and the next one is used to move down the copy well let me explain only the last Network's logic we do this contact of the first timer remember the cabin is located at the fourth fellow and IPS the second push button to and based on the previous networks the cabin needs to be moved up therefore my program enables Q 0.7 to move down the cabin all right now the cabin should go to the second filler let me select another fellow for example the first fellow and then use the second sensor now each part of the second sensor means the cabin position has decreased white fellow as you can see when the cabin is to a selected fellow the cabin will be stopped at 5 seconds and then if there is any requests for other fellows the cabin will go to selected fellow all right I hope this simple project using somatic manager is useful for you thanks for watching the video foreign
