@scoobsalamander I understand, however "Persistent parameters" feature is mainly for parameters and in some cases internal states of FBs, not inputs/outputs - see Doc: https://www.rexygen.com/doc/ENGLISH/MANUALS/RexygenStudio/RexygenStudio_ENG.html#x1-220002.5

Hi Kris,

Thanks for your post. Unfortunately the SHIFTOCT state is not persistent at the moment. The only workaround I can think of now is to store the history to the file - these function blocks may help:

• SGSLP
• MX_SLFS

However there is no straightforward solution. I have written a feature request to our developers.

Kind Regards,
Tomas

@apollo Hi Kris,

thanks for the update about compiling. My experiences are that using network drive can slow the compile process significantly and use of SSD HDD can reduce the time
It is strange that the compile took minutes when reside on local C:\ drive.

@mikeyh Hi Mike,

thanks for question. This is not about REXYGEN settings but Linux/Raspberry Pi OS settings.

The easiest way is to configure the RPi to have a static IP address.
Other method is to configure RPi to wait for DHCP server and if it won't receive any IP address then use fallback to static IP. This approach combines best from both static and DHCP.

Try to Google the keywords from above to get the up-to-date instructions.

Kind Regards,
Tomas

@apollo And how long does it take to compile the project? I tried to compile the project you send me last week with approx. 3500 FBs and it takes about 12s to compile the HMI and the algorithm is almost instantly.

@apollo said in User menu with 'Custom HTML' object:

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

Well, it is possible to upload only HMI on the target device however you should always compile whole project including all the tasks (even if there were no change in the design).
The benefit of uploading only HMI is that the running algorithm is not affected and runs without stopping.

For uploading only HMI use Expert mode in Download dialog:

@apollo Hi Kris,
this is a feature for now. The HMI generation needs to be forced when applying changes to the external file only.

Forcing HMI generation:

• Menu -> Project -> Compile HMI

or

• delete manually whole "hmi" folder

Kind Regards,
Tomas

@apollo said in User menu with 'Custom HTML' object:

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

Hi Kris, yes - it can contain REXYGEN components. The feature "findAndReplace" can be used in order to map general connection strings and aliases (used in external svg file) to the references. Just keep in my that the find and replace function is performed in the whole svg file - so be sure to make the find a replace tuples unique enough.

@apollo This feature is already part of pre-release version which is available for testing - see following post: https://forum.rexygen.com/topic/226/announcement-of-a-new-pre-release-version-2-50-next

In order to use it:

• Draw a rectangle with size of the inserted SVG
• Hit Ctrl+J (Extensions -> REXYGEN HMI -> Group Animation) and choose highlighted option

• Edit the component (Ctrl + E)
• Fill in the external file name and other parameters - see "Help" tab for more details.

Cheers,
Tomas

@apollo Yes, it does include the External SVG feature - sorry for not sending you a heads up.

@apollo At this time we are not aware of any issue on any of supported platforms. However it is still considered as a Beta version.

@apollo Hi Kris,

Thanks for clarification. Anyway, removal of all project binary files from target device can be done in the way described in following knowledge base post as you mentioned:

@apollo said in REXLANG : assigning inputs to an array of doubles:

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

Thanks for pointing this out! I will update the docs accordingly.

Cheers,
Tomas

Hi Kris,

one of the REXLANG limitation is that you can't use input / output arrays (due to internal representation).

I propose following workaround:
You can concatenate the doubles outside the REXLANG using String Function Blocks and pass the result String to the REXLANG input.

Kind Regards,
Tomas

@apollo Hi Kris,

thanks for this bug report. Please, what is the approx. polling frequency? How many items are you reading?

Cheers,
Tomas

@apollo Thanks for additional information.

What does

sudo systemctl status rexcore

say after RexCore crash?

Any information would be appreciated. We need to hunt this bug down.

Cheers,
Tomas

@apollo Hi Kris,

I can confirm that the instructions you are following are still valid - I'm not aware of any changes.

Does /rex/rexcore/ folder contain any *.rex file?

Is the rexcore service running? Are you able to download any other REXYGEN project successfully? (e.g. Getting started example)

Would it be possible to get access to the whole project which produces this error?

Thanks for cooperation.

Kind Regards,
Tomas

@rexpeter Hi Peter,

thanks for your feedback. You are absolutely right. I have corrected my previous post according to your proposal.

I got stuck in previous version of our installation script.

Sorry for the confusion.

Kind Regards,
Tomas

@apollo said in Extra parameters for REXLANG inside Subsystem?:

'll try with the GetExt function, so I'll need to create a CNS, which inherits the parameter, in the same level as where my REXLANG FB is located and use a relative path (e.g. .CNS:scv ) in the C-program, correct?

Yes, this is correct.

Kind Regards,
Tomas

@apollo Hi Kris,

if you have any spare REXLANG Input I would use it (e.g. create CNx (according to the parameter data type) and connect it to the spare REXLANG Input).

There are also functions GetExt* which enables you to read any scalar value within REXYGEN Project (see REXLANG Docs: https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=456).
Note: don't overuse this functions since it makes the Project less "readable".

Cheers, Tomas
