Hi,
I am trying to connect to a USBRLY82 (RobotElectronics) board over serial port (ttyACM0).

I have no problem sending commands to the board and action relays on it. Where I am facing issues is reading the DI status from the board and that is because to read the state of those DI’s I need to first Write() to the board and the board will send back the status once it receives the command. The value returned by the board is the value that I am trying to get. I can not get it through Read() since the Write() is non-blocking and by the time it get’s executed, the data sent by the USBRLY82 board as an answer, is not there anymore.

Is there anything that can help me with this? The read and write commands in REXLANG C-like are non-blocking. Can you please let me know if there is anything that I can do about it?

Best regards,
George

What does the Count function block do when the 32 bit Integer count is exceeded?

If you use the SELSOCT block you can choose which string you want to use by using the isw input. But how can you change the isw input with several buttons in the hmi page?

How can a multiscreen application be made?

With Multiscreen I refer to several screens to visualize data or statistics. For example, a speed statistic on one screen and on another screen the Start, stop, counters, etc. buttons to control a motor.

In short, a single touch monitor and several application screens to visualize data and perform maneuvers.

I hope I have explained.

Thank you so much

Hello,
is there any way that I can count how many minutes an input is high? On a Unipi with REXYGEN on it.

Thanks!

Hello,
is there a way to put the "source code" into the target device, so if I want to use REXYGEN Studio on another dev station I can load the project files from the device?

Hi,
can I remotely change the webpage of the HMI, for instance in case of alarm, i'll switch to the concern webpage?

Thanks

Hi there,

I was wondering if could get some help with choosing the correct block/s for the below process?

1. Use a boolean input to capture/get/display a point in time. i.e. pressing a pushbutton, captures/displays the the time “17:30:02”.

2. Use a different boolean to reset the above time to “00:00:00”.

I was thinking about using the “DATETIME” block but there doesn’t appear to be a method of resetting it to zero/nothing?

Many thanks,
Phil

Hi,
is it possible within REXYGEN to read system variables from the Raspberry Pi , such as System temperature, processor load, cpu / memory usage etc?

Best Regards
