Yes, this is a drawback of the Modbus driver and many others related to the tag generation code from the driver. I had to get away from this and look for a workaround by adding a mechanism to the code of my drivers to save the signal numbers that I want to see. As a result, I can disable or add variables without touching the signal numbering. For freely programmable devices, this is the first necessity. Yes, in other things, and for configurable ones, too.

It is hoped that the developer will listen to this problem and make some changes, at least in the Modbus driver.

You pass the value of the channel itself in the command, and you need to pass Cmd or CmdVal, that is, the value of the command

[manjey73]

SetVal(5050, Cmd)

I’m confused, do you call your application Scada ?

Add this value to the input channel and display it in a table or diagram

[manjey73]

A formula in the reference list with an enumeration for example

[manjey73]

Use the Elastic Report Plugin it can be set to the hourly version. But of course I would like to have such an opportunity in ChartPro

[manjey73]

ChartPro takes data from the minute slice and is not yet able to show the chart and export it in hourly format

[manjey73]

To fill the tanker, you must have reserved PLCs and I / O modules for critical tasks. This is not a Scada function. Think about security first. It is not necessary to burden the software with something that does not belong in it. I apologize for my English, I use an online translator

[manjey73]

You can synchronize the time to achieve parallel polling by two Scada systems, by separating the polling time. I have already tested this on RS485 lines, it works. There may be collisions when restarting the server since the initial poll is performed immediately

What Event Log are you talking about? built-in or optional from the repository ?

[manjey73]

Use RapidGate it seems to be designed for this purpose. Or are you interested in hot swapping on the fly ?

[manjey73]

@xdwokcn Do you happen to have a record of archived data in your drivers?

[manjey73]

But to work with GPIO, you will most likely have to write a driver specifically for this PC.

[manjey73]

What is Angstrom Linux based on?

I very much doubt that it is possible to install Mono on this OS

Debian for BeagleBoard

If you install Debian, it is possible to start the system. At the expense of using GPIO, you need to look at what is implemented, if there is a libwiringPi assembly, then it is also possible

Try to remove the check mark – Stay connected in the communication line settings.
