ASCII Commands Over RS485

Jan Reitinger — Tue, 01 Aug 2023 14:29:46 GMT

@georgedumitru I think the best documentation is this thread here on the forum. Byte array reading from communication is also discussed there.

Another helpful tool is definitely the example located at C:\Program Files\REX Controls\REXYGEN 2.50.12.14711\Examples\0203_Function_Blocks_REXLANG.

@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.

Cheers,
Tomas

Announcement of a new pre-release Version 3

cechurat — Wed, 07 Jun 2023 07:43:30 GMT

@mikeyh Hi Mike,

According to the screenshots provided, I would suspect that the Response timeout parameter in MBDrv is too short - did you try to enlarge it?

I also use passive tag in my projects and don't face any issues when the communication parameters are correctly set.

One more question: What is the RS485 Baudrate set in the Monarco Driver?

Kind regards
Tomas

REXduino - Communication failure between Raspberry PI and Arduino_MEGA

Jan Reitinger — Thu, 12 Aug 2021 05:09:19 GMT

@mtomek Hello,
I'm really sorry—I somehow overlooked the fact that you were posting in this old thread. The "Warning 1 1" indicates that the buffer for serial communication between the Master and Slave devices is full:

#define WARNING_SERIAL 1 #define WARNING_SERIAL_BUFFER_FULL 1

Have you added any new data communication or changed the communication speed recently? I’d also like to point out that REXduino is a third-party project, and we don’t have direct control over it. I found the explanation for the warning directly in the source code here:
https://github.com/jaroslavs/REXduino/blob/master/REXduino_slave/REXduino_slave.ino

Cheers,
Jan

Thank you Jaroslav, you learn something every day! That will help more than you know with all of my projects. especially ones with process models 🙂

Ethercat compatible?

No problem, it is only for some hobby-related stuff so no rush.

Any easy way to add a custom .js file to manage components in the HMI

@cechurat

I wanted to add that it just works on the correct size sometimes, so I'm still glad and waiting for the fixes in the future version.

Javascript

jaroslav_sobota — Thu, 12 Mar 2020 11:57:45 GMT

Hello Martijn,
here is an example with one CNR and 2 CNB constants which are controlled from web HMI via REST API: 0301-21_REST_API_Webpage_Javascript.zip

I believe that's all you need. Now it's on you to build upon this concept.

Btw, what is your motivation for building your very own HMI? From your questions I guess that using the HMI Designer and building the HMI without any hand coding would be much easier and more straightforward for you.

Let me know.

Redirecting HMI from studio

cechurat — Mon, 26 Jul 2021 17:11:30 GMT

@tcele said in Redirecting HMI from studio:

There is one last flaw that I would like to work out. The chromium instance allows the user to use gestures and go back and forth in the history of pages. In some cases get to a restricted page this way.
I googled vigorously to solve this issue, but so far to no avail. Any advice on this topic?

Hi Ivan,
I wasn't successful in finding any suitable solution as well. Have a look at xinput command which might help you to disable all the gestures at Linux level. I didn't tried it myself however if you find any working solution our team and the community will be happy to hear about it.

Cheers,
Tomas

EKF example

@Jan-Reitinger Nice. Just one small remark: There's no need to use a two-dimensional input here—even formally. You can define a system with a one-dimensional input, a certain number of states, and possibly a different number of outputs. Instead of using u(t)=[sin(2πt);0] you can simply write u=u1=sin(2πt).
