Hi Jaroslav,
Amazing, that are interesting blocks you used to achieve this.
Thank you very much for this example, I 'm certainly will make use of that!
PS: would it make sense to expand the INFO block with also a Revision field?
Software is in my point of view never "finished" and adding a revision number in the INFO block in that case also can be used in the HMI as a kind of "About" screen with all information about this application created.
Best regards,
Peter
Hi Jaroslav,
Thanks for the feedback on this.
Indeed that is there and when I'm connected to the target I would be able to see it.
However if a unit is in the field, and the user in front ONLY has the User Interface, I would like the user to provide me the version (or Revision) of the project and the time stamp when I build / download it.
So it should be in the User Interface (HMI).
Is there a possibility to link a "string" of this identification screen into the HMI Designer screen?
And specifically it would be nice if there was a feature to automatically update the Revision number (as well as text string) every time you rebuild (compile) the project. Manually changing the Revision number whenever you create a new one will work, but might be forgotten and than we might deal with 2 different versions that you are not aware off since it has the same "version" number...
Maybe on the "wish list" if this does not exist yet?
Best regards,
Peter
Hi,
Is there a possibility to automatically generate a time stamp + revision number at the moment you compile the project (and load it to the target?
It is not complicated to generate a time stamp and revision number, but I'm looking for a more automatic method to differentiate when which revision was loaded.
Especially when a project is in further development, it sometimes is difficult to know / check when and what revision was used.
Adding a revision number manually and display it in the HMI is not a problem at all, but creating a "permanent" time stamp at the moment you compile the project is something I did not figure out yet.
Any input is appreciated!

Peter
Re: 0302-11_ESP8266_REST_API_example
Hi all,
I factually succeeded to use the ESP32 with a digital Temp. / RH sensor connecting to my Raspberry Pi.
However I'm wondering if I also would easily be able to get a kind of "Status" signal from the ESP32 (created in the Sketch) that is giving me feedback if there was a reply received, just like a "Modbus connected" signal.
If the ESP32 is no longer updating the various parameters because there is no communication anymore, it would become handy to be aware of it.
I assume it would not take much programming in the sketch, but so far I'm not vary familiar with the arduino IDE programming of an ESP32 (or ESP8266).
Any feedback would be appreciated.
Regards,
Peter
@cechurat
Thanks a lot Tomas,
I will have a look at the example later this afternoon.
Thanks and best regards
I'm looking for a function block comparing two strings and generate a logic output of "1" when equal and "0" if NOT equal.
But I could not find a string function block that is doing that. I noticed the STOR block and tried to convert to real and compare the real values, but the output of the STOR block is always "0" so when comparing that with another string that was converter to Real is not working.
I guess I might have overlooked another function block that I need for this purpose.
Any feedback on this will be appreciated.
Best regards,
Peter

Thanks a lot for your feedback and looking forward for the update to make this possible.
Thanks for the tip about https usages!

Hi,
I"m wondering if there is an example how you can replace characters when typing. Like you do for many websites when entering a password.
So I want to use a typed string from the HMI in the "task" block, but want to replace the typed characters with "***" characters.
Looking forward for feedback on this.
Best regards,
Peter
Hi Tomáš,
Excellent, did not thought about doing it in that way, but that is exactly what I was looking for. Thanks a lot!
Peter
