A good essential point is to incorporate the pulse function, in ladder it is used a lot for push button inputs.
Thus, even if the button remains pressed, we only allow one input pulse.
Hello,
First of all, thank you very much for your participation.
A trigger block was added recently, it seems to me to meet your needs, it manages rising or falling edges. The attached example shows a use of this block to implement a counter
Sincerely
Hello, thanks for answering.
The idea is not for accountants although it is important.
My request is to implement it anywhere in the circuit.
I mainly use it on push button inputs like the attached example.
With the pulse function we save components and it also has a very important function in motor starter systems.
I always try to put a pulse on the start button because if for any reason it remains activated, when pressing stop the motor is deactivated but when leaving the stop at rest once the start is activated the motor starts again. On the other hand, if we insert a pulse after the start button, it will only start again when we press it again.
There are many functions like the counter, but without implementing the edge, only with the pulse. All the interpreters of the major PLC brands have this function.
Another sale is to optimize the set reset with the pulse, it allows it to be applied much more easily and with fewer components.
For example.. Try to do a SonOff with a single button.
Hello
I fully understand your need
And the current version of NSLadder responds perfectly but differently than your example
See the proposed solution, what do you think?
I have been testing the software and it really is the function I was looking for.
The problem is that the symbol confused me and I thought it was a trigger with a rising or falling edge. Not a pulse. Sorry for the confusion.
Thanks

Hello, excuse my boldness, how should I address you, my name is Joan.
Regarding the Software, it is working very well, although these days I spend little time on it, it seems good to me.
Two questions and I apologize for my mistake on the flank, I thought it was a contact with a rising or falling flank and when I tried the examples I saw that it was a pulse with a rising or falling flank.
So the text of the button should be "PULSO", the rest is fine.
The translation into Spanish is correct, if there is an error I will tell you.
The APP has a TON, but not a TOFF, in ladder it is good to have both timers.
I send you a theoretical scheme.
When we close contact E2, TON counts the time and at the end activates the output.
A2.
Closing contact E3, TOFF activates output A3, and when we deactivate E3 the timer counts and disconnects output A3.
If I have not explained myself well, let me know and I will clarify it for you.
Greetings.
Hello
In my youth, I worked on PLCs (SMC, APRIL) which only had one type of tempo. However, this function is now available on most machines.
This will be implemented in the next version.
The "model" page is at the beginning of its life, many developments are in the notebooks, in particular text areas...
Currently I am working on a VM for Raspberry
Thank you for your active participation in this project
Greetings

I have worked with various brands including Siemens, S5 and S7.
Also in Modicon for the distributed control of the plant and in all the buttons we use the pulse option for safety, since if a stopped motor was pressed even though the start button had remained pressed, the motor would stop. (bad practice of the operators, they hold the button with chopsticks)

Hello,
Thank you for updating the APP with the timeroff.
I have tested it and so far it works very well.
Now I have an error when I want to simulate the Arduino in the App, two errors appear that I leave in the image.
Thank you so much
You simply have to reinstall the VM (V2.1) in the Arduino. I will add a version control of the VM, to see if it is in phase with that of the current program.
What are for you the essential evolutions to develop ?

I added 3 examples to download :
* demo on-off with trigger two buttons
* demo on-off with trigger one button
* demo on-off with trigger one button and timer
Sincerely

I will look for a more relevant icon
Is the Spanish translation correct?

the TOFF type timer has been added to the project (NSLADDER V0.3.5)

Hi
I come to the news
Hi,
Yes sir, I tried your indication and for now it works.
Reinstall the VM (V2.1)
Thank you.
