Hi Mike,
glad I could help.

A "good execution rate" always depends on the project. 20 milliseconds might be too long (controlling RPM of a motor or detecting pushbutton presses or counting pulses from a flowmeter) or way too short (temperature control).

It's the responsibility of the system engineer/designer to find the appropriate timing.

As for Modbus, we typically use twice the rate of the task which is using the data provided by the Modbus driver.

Hi Martijn,
if you mean 2 separate Raspberry Pi with Unipi 1.1 on top of each other, then yes, it is possible. It is a question of getting data from one device to the other. For this purpose you can use:

RDC function block (see example 0202-12) REST API of REXYGEN (see example 0302-01) Modbus TCP connection (see example 0402-01)

Hope this helps, let me know.

Best regards
Jaroslav

Hi Eric,
thank you for sharing your subsystem.

How about turning it into a library? See Chapter 4 of REXYGEN Studio User Guide.

Minor personal note: I'd use the REL block instead of the CMP block in this case.

Thanks again!

Best regards
Jaroslav

See example 0122-12:

Please start a new topic for questions not directly related to the original question.

There is no such block, you must combine the existing blocks to achieve this.

Software is in my point of view never "finished"

Tell us about it 😉

Your recommendation regarding revision identifier is in our pipeline. Since Monday already. Thanks!

Hello,
I do not have any better advice than to add this line to your code, which will make the compiler believe that the variable dateInterval is used.

dateInterval = dateInterval;

Can you share or send your code leading to such a false warning? Thank you.

Jaroslav

Can you give me an example how to do that with that function block I can't figure it out myself?

@enovikoff said in Measuring water flow with UniPi:

after searching fruitlessly for a Pi HAT that included a counter

What about the Monarco HAT? It has 2 high-speed counters onboard...

@martijnperdaan said in Database:

Schakelaars

the input SwitchOn is variable sometimes it is Switch1On and sometimes Switch2On and sometimes Switch3On

so he has to read the value of for example Switch1On from the tablet Switches
for example, he should get back 01101010 as answer because it is stored underneath but he returns Switch1On in response

the system does not log an error because the SQL command line must be normal

Thanks a lot Tomas,

The OSCALL function block appears just what I needed.
Thanks for making me aware of this block.

Kind regards,
Peter

I created a "ProwlPushMessage" block (SubSystem) where all properties can be set easily.
Implemented the conversion from a "space" character towards "%20" in order to get the correct code for the message.

So this system is ready to be used, only fill in your own APIkey and press the button to send a message to your iPhone.
Please find the project attached.

This is how it looks.

@RexPeter thank you for that, that is actually very useful.

Cheers

Mike

is there a special way or maybe you need to install extra stuff with rexygen on a Neuron L523

whatever I try I can't get it to work

get this error code

12-8-2020 21:53:30.432 Error MBDRV: Socket receive error (idx=0, code=111)
12-8-2020 21:53:30.432 Error MBDRV: Error while receiving data(ignore, code=-309)

Hi Günther,

there is no official REXYGEN 2.50.10 yet. However you can install pre-release version - see following forum post: https://forum.rexygen.com/topic/120/installation-of-rexygen-2-50-10-testing

Once there is a new release you will get notified.

Thank you for understanding.

Regards,
Tomas

Hi Tomas,

I tried your proposal, but unfortunately it did not work.
At the end I decided to simply re-image the SD card and start from scratch. Installed the most recent Rexygen test version and now, all is working fine.
Thanks for your support.

Best regards,
Peter

Hi Peter,

yes, this is also one of changes in newest release version - subsystem mask dialog. And you are absolutely right - changing type to Enum does the job.

Is there anything else you struggle with? Just let us know.

Cheers,
Tomas

Or, possibly N DEL blocks may also do the job.
