@jaroslav_sobota no problem 🙂

Thank a lot for explanation Ondrej.
I will proceed accordingly.

Best regards,
Peter

@rexpeter You are welcome 😉 Glad I could help.

Cheers, Tomas

After installing Buster Lite Image I made manual install of owserver.
sudo apt install owserer
During that install I got the same error messages.
Reboot and install rex with unipi script.
Everything was installed without any error.
Raspi is up and running without any issues.

Thanks for the explanation, now I understand. Nice solution.

Jaroslav

ok thanks for the answer, i will try.

Ok, thanks Jaroslav.

I'll use a combination of the ALB and what I currently have to achieve both. This way I'll get both live HMI and logged alarms.

Cheers

Mike

Hi Mike,
I see. In that case the simplest approach is to use the TSE block (three state element), which moreorless combines two comparators with hysteresis.

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.

You have remarked very interesting points! ps decent website. link text

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

Hi Mike,

I wasn't 100% right, sorry for that.

It is prohibited to use both flags for AI at the same time by the compiler. The solution is not that straightforward however it is possible:

use just "MNR_AI1" flag to set the current mode use SDC write flag, address 0x00A - bits 01 and 02 (see docs: https://github.com/monarco/monarco-hat-documentation/blob/master/Monarco_HAT_SPI_Protocol.md#service-channel-register-description) when in current mode you need to manually convert the value by following formula 10V = 52.475 mA

If you need any additional help, let me know.

Cheers,
Tomas

It would be (time-wise) more convenient for me to create one SVG-object which can display all different statuses from a single alarm. Now the connecting of all these different alarm-bits in HMIdesigner is really time-consuming... but I'll manage... 🙂

That's why I think that it would be a better solution to make a custom SVG that accepts a byte with all the necessary info...then only one connecting string is needed for one alarm. But for now, I'll stick to what I'm already doing because following the path of creating new custom objects will cost me even more time I'm afraid.

@mikeyh Hi Mike,

Monarco HAT is grounded through Raspberry Pi (via 40 pin header). For complex grounding you should also ground GND output of power supply used to power Monarco HAT and Monarco HAT metal case. Could you please try it?

@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.

@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
