Support Questions / Re: Exit Button on MainMenu

« Last post by Automatikai on April 30, 2024, 12:06:28 PM »

OK, I think I got it. Use MainMenu buttons for all navigation from the menu rather than formchange. I think I was assuming they all went to mainform.

Still struggling with screen positions and sizes.

Support Questions / Re: Exit Button on MainMenu

Additional problem: I migrated my menu controls to my main project. If you put a formchangebutton on the mainmenu to the page2 screen, it closes the mainmenu, leaving the mainform and the page2 open with no way to exit. This implies that the formchange buttons would need to be on each screen to navigate rather than on the MainMenu, which should always stay open. I must be missing something.

Support Questions / Exit Button on MainMenu

« Last post by Automatikai on April 30, 2024, 11:11:11 AM »

I realize this may be a VS question rather than Advanced HMI, but I am a rookie so bear with me.

I developed an application first using the MainForm, OPC driver, it worked well with an AB emulator. I added a FormChangeButton to Page2, put an OPC driver there and page2 controls also worked fine. I put a FormChangeButton on Page2 back to the MainForm and it didn't close Page2. I also went to the FormChangeControls folder and spent some time  looking at the code trying to figure out how to implement it. For instance, the exit button seems to have a ExitButton_Click Sub but no code inside. It tried using it in that application and it didn't close the forms or application. If I close the MainForm with the "X" I get a StackOverflow.

Next I created a new test application using MainMenu as my startup, MainForm as my startup form, a FormChangeButton to page2, a FormChangeButton back to MainForm. Navigation seemed to work ok, but the forms don't start in the same place. I saw some commented code with MenuPos and assume that helps put forms in the same spot, I will experiment with that later.

But the exit button doesn't close the application or forms. I have seen some help files referencing Me.Close() but when I put that in the ExitButton_Click sub I still get a stackoverflow.

To use Advanced HMI it seems that a deeper knowledge of VB.net and Visual Studio is needed, but short of an intensive bootcamp or school I don't know where to start. The Microsoft and YouTube videos and files I have found all seem to skip the fundamentals also. I have done some work using OOP in Beckhoff so I somewhat understand properties, methods, inheritance etc. but this gets over my head fast. Any suggestions?

Support Questions / Only reading 1 array register

« Last post by FlippinBits on April 27, 2024, 02:59:02 PM »

I'm having a strange problem.  I have a page that just reads values from 2 PLCs.  One is ControlLogix which is working as expected.  The second is CompactLogix which has the problem. Using the same driver for both.
I am reading an array of values.  The displayed values are all the same as the first set in the array.  So, it reads the first row, then the second row is the same values as the first, 3rd same as first, 4th same as first.
I am just using the Basic Label addressed to each element.  The PLC address is correct in Properties, but that is not the value that is displayed.  Using version V399x Patched3 of Advanced HMI.
Any ideas?
TIA

Open Discussion / Re: AdvancedHMI TCP to DL05 RTU Communication

« Last post by Godra on April 19, 2024, 11:53:24 AM »

You should get in touch with the manufacturer of any Modbus Gateway you might have been checking out.

Ask them if their device can both send and receive.

Open Discussion / AdvancedHMI TCP to DL05 RTU Communication

I am looking for a device to communicate between TCP and RTU in both directions. I have looked at Modbus Gateways but it seems they only communcate RTU to TCP. I need to send and receive. Any help would be greatly appreciated.

Thanks Archie! I didn't know about the AdvancedHMI Files folder, I'll have to see if what I am wanting to do is built into any of the Sample Projects.

I am happy to share the document I am creating that encapsulates many of your program comments, just let me know where to put it. It will be a living document, I learn best by documenting what I do.

As far as training, I would imagine that most of the industrial automation focused users of the software have the same problem I do, a lack of experience in Visual Studio. A good VS class would be useful, but probably would take years to become adept in. I teach PLC classes for AB, Siemens, Omron and Beckhoff, and students only pick up the very basics in a week. I always tell them it takes years of practice on real-world applications to become adept at it, and they rarely have the opportunity to write their own code and build equipment like I did coming up. I teach TwinCAT only to people with a firm foundation in ladder from some other platform, and it is MUCH harder to teach things like OOP and ST structures to people with no practical coding background in a non-graphical language. Also for most of them their company pays for the training, companies have much deeper pockets than individuals.

I tried to attach a pdf of the document here, but the max file size is 512k and the pdf is 1.6MB. I am also happy to share the Word format with you or anyone who wants to collaborate on it. Let me know how I might share it.

AdvancedHMI does lack public documentation because years ago this was done by intention in order to give an advantage for attending the training classes. There was an attempt to create a user driven documentation wiki, but thanks to spammers, that had to be locked down:

https://advancedhmi.com/documentation/index.php/Main_Page

There was also a repository for samples, which is now fairly old:

https://sourceforge.net/projects/advancedhmi/files/advancedhmi/3.5/SampleProjects/

Any suggestions along with offers of help to improve the documentation is always welcome.

Hi Archie!

I don't know if you remember me, but I visited you several years ago asking about animating objects in Advanced HMI for a ControlLogix HMI. At that time I had not done much with Advanced HMI, or for that matter Visual Studio.

After doing some research on VS I found many suggestions for code development, including that of committing code to Git so that things can be tracked and reversed. I have also looked through this forum as part of my learning experience.

As many have mentioned here, most questions are solved by looking for help on VS and Visual Basic/.NET, but it opens a huge can of worms for those of us who are very experienced in PLC topics but not app coding and all the associated languages.

As part of my learning journey I have taken many of the help files and comments in your software and put it in a Word document with chapters, headings etc., which I would be happy to share with anyone who wants it. Unfortunately I don't see an easy way to collaborate on such a document, so right now as I find different questions that need to be answered I just write them up and add them to my document.

I am still struggling a lot with some basic things that would be simple if using FactoryTalk View, WinCC or even VISUs in CodeSYS or TwinCAT. Things like screen switching, creating an interface for setting up communications (IP address, slot number, subroutine concatenation with tag addresses, etc.) I am sure this has been done by many people, but despite this being an open platform I have found very few code examples that help answer my questions. Without my work in TwinCAT and CodeSYS I would be completely lost in Visual Studio.

Several regulars on this site have rightly chastised new members for not researching Visual Studio coding more before asking questions, but I fear it is a multi-year exercise to learn the ins and outs of this type of coding, even with my extensive experience in programming PLCs, including ST.

Any pointers you might have in finding more examples of deployed HMI code or better VS training?

If those posts don't make any sense then delete them.

You can always give them a chance to make sense by responding to their posts.

Just my opinion.
