As usual, very valuable information. Thank you so much!
Our pleasure! ❤❤
Thx u for the vid , about DI EI instruction I understand that first we must press the contact which enables interrupts b4 pressing x2 or x3 , I loved function block it's very useful
Thanks for checking the channel, and glad that you found lectures interesting and useful!
Great job !!! thank you !
Thank you too!
TAHANK YOU TEYCHER
Thanks as well!
Thank you, it is useful video, I need loop function.
You are welcome
Thank you, it is useful video, I need to know how measure weight using load cell and delta plc
Thanks for checking out the channel. I do not have any project done regarding application of Delta PLC and any brand of load cells
GOOD
Thanks for checking out the channel
I really enjoy your videos. Do you have thses notes on a pdf document?
Thanks for checking the site, sorry I do not have any PDF for any of the lessons
Hi my friend !
Why do I need for loop if the program execute the conditions anyway?
Hi there, I agree with you and I rarely use the loop instructions (For & Next). So, I explained them briefly during the video. especially they can increase the scan cycle time, therefore I prefer to use other techniques or instructions. For example, A number can be multiplied by itself several times inside a loop, But I prefer to use mathematical commands like power instead of using a loop. However, most programming languages support loop commands. For & Next determine how many times a part of the program will be executed in one program scan.
Thank you mr
There is problem with the (cj) instruction in writing the command (s)
Some of them show an error massage
What is error
And thank you
Hi there, when you compile your project, ISPsoft can detect some errors in your project and display them at the bottom.
Also, a few instructions are not supported by some older version of delta PLCs. Please check your PLC model and read the instruction's description in the help window.
hello sir . i'm using 3 functions that uses the same outputs but they can't work simultanely they depend on a decimal value however when one function gets activated it keeps the values of the outputs that it sets even if I turned the function off. i need some help to when I call a function the other function stops and their outputs resets is there an end loop or priority function I could use ?
Hi there, It seems you have 3 functions, and based on some conditions (as you said: a decimal value) only one of them must be executed. I think you need to modify conditions that enable each function. also, you can use them to reset some variables before starting another function. My recommendation to you is: define 3 outputs related to each function and then select one of them based on your conditions at the end of your program.
Nice video sir, btw i am using DVP32es2 delta PLC and i have a problem for my project. Let say, the electricity suddenly went down in a factory for a few minutes. And when it turned back on, I wish the PLC to suspend the current program. So the operator can decide via hmi whether he will continue the current program or reset it from beginning. How to use EI & DI in this case?? Thank you very much
Hi there, you can easily write any part of your program inside a Function Block, then write a simple program inside the main program to call each function. related to your case, the operator determines which function must be executed. the main function which controls the system with the previous data, or a function that clears all previous data and after that runs the main function.
@@plcgoodsmentor9223 Thank You for your advice, currently i just use latched memory to continue the program when it suddenly went down. And also put reset button , to reset all the program and the values.
Now it is your turn to try to write your code with the the answer. Let me know th result of your next try
Can we operate a input from HMI and Push Button
You can use HMI to change memory bits and then use them in parallel with a pushbutton (X0, X1,...) to turn on/off outputs.
Dear sir I need help as I m on job
In my program isp soft 3.16 don't hane function like extranal input x0.2 don't have rising and falling edge choise pl explain me which program u r using
Hi there, First of all, I explained how to download and install the last version of ISPSOFT in one of our videos (ua-cam.com/video/DKh7qbtH2p4/v-deo.html), and please check the other inputs. If you can work with others, maybe your wiring related to input x0.2 has a problem.
Also notice If you select another PLC model in the ISPSOFT software, maybe the instructions' structure, on the left side, changes a little and you see new instructions or categories. Therefore you have to find rising or falling edge instructions under a category with a different name. You can use the help window to search and find your instruction.
thanks for checking the channel out !
Hi sir I’m facing problem in position control mode, with two signals such as x0=1 for starting the pulse output about k2000 pulse,
and during servo running I give another trigger from x2, in that case I have to stop the servo at k1000 pulse from the trigger of x2, in between servo should not rotate
In this case if the frequency is changed position is changing
Can u please guide me the steps to be followed
Even frequency changed position should shouldn’t change
@@Decorpacz Hi there, I've never connected a servo to a delta PLC and also your question is not clear to me :(
@@plcgoodsmentor9223 ok is there any other way to communicate with you ?
communicating with the mentor is limited to placing comments limited to the related project done in that particular video clip.
can i run this instruction(DI EI) in ispsoft simulator ?
I think so, Try to test it. Note that, based on the selected plc model, you can see valid instructions on the left side. Also, based on the selected plc, use an appropriate simulator
@@plcgoodsmentor9223 i have try in SE simulator but showing error y2 and y3 output....but your method is very nice ..I ll try this logic in another model .I hope it will work . And I hope you will make some more videos ..
ok, let's Cross our fingers that it will work!
Where is the for next
Hi there, "For" and "Next" instructions were explained briefly at 7:16. However you can also use the help window to see more details about each instruction.
