Hello again. After a lot of trying and trying I found the cause, at least I think so, but it doesn't work as I had thought. I'm going to have to rethink this whole process again but in any case, thank you all for any and all help you gave, especially to IO_Rack for their availability and attention to this question. Thank you very much

IO_Rack, the plc is an omron cqm1- cpu 41, the speed variator is an omron j7 which does not have any communication, understand, it does not have modbus communication or anything like that, so my idea was to use the speed-up commands and speed-down of the variator's digital inputs and control them by the PLC. In the previous post I attached an example of what I had thought of doing but I don't understand why the plc outputs are either the ones you see on the cpu or the ones on the first output card. Please note that this example is made for a cj1m, as I have it here with me at the moment so I can test it, then it will be converted to the cqm1. Thank you for any and all help you can give.

Guys, I already found the solution. I'll leave it as an attachment as it turned out, as it might come in handy for someone else who, like me, still has a lot to learn, eheheheh. Thank you to everyone and especially to IO_Rack for your availability and helpful spirit. Until next time, doubt Thanks. contagens (2).zip

Hello everyone, once again I come to ask for your wise help to learn how to do it: How to calculate square meters with cj1m. Let me explain: I have a cj1m-cpu22 to which an hmi ns5 is connected and they asked me to make a screen that would display the number of total pieces produced, the pieces per minute and the square meters produced, which at the end of each shift will be reset. by the operator after taking note of them. I leave the network I made to see how the counts of pieces per minute and total pieces are done Thank's for help.   contagens.zip

IO_Rack, first of all, thank you for your willingness to help. " Can you multiply the length * width then multiply by the number of pieces? " This is truly my problem. I've tried everything I know, that is, very little in calculations with the CJ1M, and I can't get the math to add up. I know that by multiplying side times side I get the area of each piece and then multiplying by the number of pieces I get the so-called square meters but my problem is that in the HMI the operator enters the measurements and these go to the PLC in HEX. This is where the problem is, for example, let's say the piece is 0.200 x 0.200, the operator enters side A = 200, side B = 200 and now my fight begins. How do I make these values so that side A = 0.200 and side B = 0.200 so that I can then multiply with the number of pieces? Thank you very much in advance for any and all help you can give in my learning process.

Well, I was just curious, nothing more, and no, I won't do it, you can be sure of that, as I said before, I don't know how and I don't think I have the knowledge to do so. But it's very interesting, yeah. ;)

Good afternoon everybody. Is it possible to create such a thing as the title says, omron function block that inhibits machine operate??? How will this be possible?? I would like to learn how to do it. Can anyone give me an example??? Or how is it done??? Thank you very much in advance for any and all possible help.

pturmel, thanks for the answer. I just wanted to know if it was possible and how it would be possible to do such a thing, I wasn't, nor am I thinking about doing something like that, because I don't have the knowledge to do it. I find it interesting that it is possible to do a function like this but I wouldn't do it because, as you say, if I understood what you wanted to say, it could cause problems for a client with its production and of course, someone committed to understanding why the machine doesn't works could know what was going on and delete what was done, besides it would have a bad reputation for that client and therefore other future clients. But anyway, thank you all for your opinions and sharing your knowledge.

photovoltaic, that's interesting. Thank's for the information.

First, thnak's for your reply IO_RACK. Well, what i have in mind is some FB that makes stop a machine to work if someone doesn't have paid the license, for example. Is that possible???

I need help to understand how communication with frequency inverters works in this example, as I need to add two more and I don't understand how they communicate with inverters. I leave a copy of the HMI program so you can see it and who knows, maybe give some tips on how this was done so that I understand how I should add the two variators. Thank you very much in advance for any and all possible help. https://drive.google.com/drive/folders/11UYEAE84POiYTIa8j7lu9xD3CXfrDAiW?usp=sharing

Guys, I already found what I was looking for. I leave you an image to see what I needed. Anyway, I want to thank everyone for any and all help. Thank you and see you next time.

Hello, I can try to help you. I already had to do the same with a very old HMI and I managed to get everything working. But you have to share the programs with me so I can analyze them and try to understand how they did it.

Thanks for your answer, I know that part, my big doubt is that I can't find any of the HMI program anywhere, a reference to a modbus address and the strangest thing is that it is working, sending the speeds and saving the same in the recipes. As I need to add two more variators, I wanted to understand how they did this so I didn't have to change the entire program but rather copy what was already done and then adjust it to the variators I'm going to add.

Hello everyone, I'm here to ask for your help so I can change the parameter designations on an omron ns5 hmi. I know that each parameter is in a list within the HMI, I know that what defines each parameter are the move functions right at the beginning of the program. My biggest question is how to make the number of each line in the list correspond correctly on the HMI, as I've tried everything and the parameters don't appear correctly. I am attaching a copy of the PLC and HMI program so that you can check and perhaps explain to me how I can do it. Thank you very much in advance for your help. https://drive.google.com/drive/folders/1IV2TtB0XFRs_IpGMCBxe_DNyniYNVzzV?usp=sharing PLANO ASPIRANTE SAIDA RETIFICADORA.zip HMI.7z

Guys, I found the solution. The correct line number is calculated like this: line number times 2 minus 1 and this is the value that must be entered into the move for the message to appear correctly. Anyway, thanks everyone for your help.

Thank you very much for your quick and knowledgeable response, this was my problem and I didn't see it. Thank you very much. Hug.

Good morning friends I need clarification, for which I leave a copy of the program under test, as I need to understand what is going on with this problem. In the test program that I leave you, every time I change the d10 to 500 pulses, the rise and fall do not stabilize as for example with 400 pulses or 300 pulses. Can anyone help me understand what's going on with this??? Thank you very much in advance for any and all help you can give. Rui Silva simulador de movimento dos mandrins.cxp

Can you send me your e-mail for we can exchange ideias?? I think that you can't do it with this progamable relay, cause i can't see for now anything that alow you to change the value on the timer and/or counter, cause you can use a counter and a 1 secunde pulse generator. Do you have any experience with another type of plc??    

Can you post what you have made so far?? I try to help you to do this to work.

After much trying and trying, I found the cause of the problem that brought me here. Just one box checked that was causing the whole problem. I want to thank you in advance for any and all help, especially pturmel for the tip he gave me, which in a way was very helpful in finding the culprit of this problem. I attach a print screen so that if anyone else has the same problem as me, they can help with this issue. Thank you very much Rui Silva

Hello everybody. I come to ask for your help for a problem that I come across with a hmi weintek mt8102iE. The idea is to send counts of parts of a machine by e-mail to the logistics department. I have this feature working on two other machines but with hmi's mt8103iE, which have wi-fi and are working perfectly. My problem is that I bought a network extender, tp-link tl-wa855re, to connect the hmi mt8102iE to the network, since I don't have wi-fi, and it's only possible for me this way, a network cable is not viable , and I can't get the hmi to send the email at all. Can someone help me with this situation. P.s.: If I simulate the hmi on my pc, it sends everything I want but physically not. Thank you in advance for any and all help you can provide. Rui Silva

pedroborges, did you get the solution for this???  

Hello, try and read this post, it may help you i hope.. https://forums.mrplc.com/index.php?/topic/42064-readings-from-cx_programer-to-hmi/

With Modbus Poll try f4 instead of f3. F3 = function 3. f4 = function 4. Try with f4, which should let you write to the registers one by one, until you find what you need. I hope I helped and that you find what you need.
