Today I moved the complete project from my mobile HDD to the local network drive and started compiling + download;
This time it took 6minutes and 15 seconds without the downloading.

Then moved the complete project folder to the documents folder on my C:\ drive, again it took several minutes.

Connected my mobile HDD with the original copy of the project and tried again.... 10 seconds without downloading

Second attempt with a new copy on the network drive gave me the same result....it took minutes to compile.

... so far the testing....

@mikeyh

Maybe you can also make the parameters of function block SHLD non-volatile (Persistent parameters).

If you restart your computer and/or download new program then it will not lose the previous stored value.

And storing the value every midnight in a database and then trigger the SETH input would give you a nice overview of the daily consumption.

@cechurat this varies a lot. Now I compiled, without any updates, within 20sec (downloading included) And with or without Webwatch doesn't make any difference. In the past, with the same project, there were times that I could easily get myself a coffee while compiling. Maybe I should restart my workstation more often? This computer remains running 24/7...
I still don't know why it is sometimes compiling very fast and other times really slow.

The same, slow, behaviour I noticed during programming as well. You double click a function block to open the properties and it takes 2, 3 seconds. It doesn't seem a lot but it is annoying and especially if you know it is not always like this.

For the moment I am at work but at home I have had the same behaviour.

20s is of course not a problem
If it happens again I'll let you guy's know, for the moment it's perfect;

@cechurat ...it's the compiling which always takes quite some time on my computer, especially when the project is getting bigger. I already excluded the WebWatch in the HMI block which is already a big timesaver if you do a lot of compiling.

@cechurat This button exists already quite some time but I never understood the purpose of it.... good to know.

Btw, what is the best way to only compile and upload the hmi-files without having to compile all the tasks?

@cechurat After uploading my initial project I did some changes to the external SVG file but this was not recognized when I did a new download. None of the hmi files were processed and thus not updated although I had made changes to an external svg file which was used in some of the hmi-pages.
I needed to make a small change in each hmi.svg-page to trigger this processing.... a small bug I guess. Is there an easy workaround?

Just did a quick test with a local connection type and it is working, so I guess the other connection types will also work.
This is a huge improvement for our project, it gives us the possibility to create a menu that is found on every single HMI-page.
And if I change something to the menu I don't need to copy this to all separate hmi-files.... super.

@apollo Btw, can this external file contain REXYGEN objects?

@cechurat Thank you, I'll give it a try....

@cechurat All working fine it seems....

By the way, thus this version already includes the external-svg feature which you mentioned in following topic : https://forum.rexygen.com/topic/193/user-menu-with-custom-html-object/3

@cechurat Is it already a good idea to try this out on a Linux system (Debian / not RasPi)?

@cechurat yes, only I could not with sudo, only with su. Don't know the exact difference.

Thanks for the info, it is working now.

@cechurat I was still thinking that the input could not be of the string type.....

Is it possible to assign the input signals to an array of doubles?
I tried several syntaxes buy I end always up with errors.

My final goal is to convert them to a string and concatenate before sending by means of UDP.

something like this....

        string temporary ="";
    	for (a=0; a<12; a++){
	    	strcat(temporary,double2str(signal[a]);
	    	if (a<11)
	    	{
	    		strcat(temporary,',');
	    	}
	    
    	Write(long handle, string data)
    	}
        dataCnt = Write(hCom,temporary);

@cechurat I am not 100% sure. I am not in control of the PC that is running this Keptware software.

I believe that it was originally set at 1Hz but I am not sure, but when it was set to 0,1Hz it was working fine.
For the moment it is still crashing the application because I believe it is set at a too high polling rate again. (I assume....I am not in control and do have no access on this PC, so it's hard to verify if this is the real problem.)
But if I change the port number of the OPC UA server to make sure nobody is polling the server then everything keeps running fine.

It would be good that only the communication would stop and not the entire rexcore.

I will send you a PM with the complete setup.

@cechurat

This crash is related to the other topic I started with the polling by an OPC UA client. But this screenshot shows what is happening after such a crash I believe.

@apollo said in Removal of all binary files of your project:

When the OPC UA client (Kepware) is polling the OPC UA server then the rexcore is crashing and there is no more communication possible anymore. (even downloading a new program or diagnostics isn't possible)

It seems that it causes the rexcore to crash when the polling frequency is too high.

@cechurat yes, I can download other projects but I first need to disconnect it from the network and setup a small local network with only the PC which is running the rexcore and with my notebook. Otherwise, it is not possible to do anything.
Once I start the rexcore it is crashing almost immediately which makes it afterwards impossible to connect with the diagnostic tool. With the local network only then this problem does not occur. so I guess it has something to do with the Modbus driver or with the OPC UA server which is running.

A previous version from our project is running fine, if I remember well then the only thing I changed are some HMI pages. Still have to find out what went wrong.

This is the current status (the error messages are from missing Modbus TCP slaves which are configured in the software but physically not present on the network). But they never caused any problems before....

Used su and now it is possible.....

Is it normal that after removing the binary files I am still able to restart the rexcore...?

Is it possible that this has changed since one of the latest revisions (https://support.rexygen.com/help/restarting-rexcore-runtime-module)

Because I am not able to download anymore to the rexcore I was trying to remove the binary files but without success.
