Possible. The developer has experimental builds for libplctag_2.3.4_linux_arm6hf_EXPERIMENTAL.zip and libplctag_2.3.4_linux_arm7l_EXPERIMENTAL.zip
If any of the builds are suitable for Raspberry, I can try to rebuild the driver for them. But I unfortunately have nothing to test on. I have already returned the PLC and I do not have access to it. If you can arrange remote access to the PLC, I can try to check this possibility.

I didn’t pay attention, you have a cheap USB-RS485 converter, I have the same ones.
But I have only 3 pieces installed. And at the time of reboot, they can change their numbers, for example, from /dev/ttyUSB0 to /dev/ttyUSB1, which is unacceptable for the system to work.
So I apply the Udev rules so that they are named as I want, regardless of what number the device received.

Here 1.3 is the number of the USB port on the Raspberry and /dev/ttyUSB0 what is the port number received by the device

[manjey73]

Run the
dmesg | grep usb
command and look at the output, there you will find the port number to which the USB-RS485 is connected, and in your case, most likely the serial number of the device. Cheap devices don’t have a serial number and can only be linked to the USB port number on the Raspberry

UDEV rules must be applied when you connect two or more USB-RS485 devices. In your case, it will most likely be /dev/ttyUSB0

In general, by default, all ports have the form /dev/ttyUSBx, where instead of x, the number is from 0 and on. But if you have two or more devices, sometimes the numbers change. So that the number does not change and the Udev rule is made and the device has the same name, but it is bound to a specific port via symlink.

[manjey73]

Udev rules

Use an online translator. The rules can bind the USB-RS485 converter to a specific port name, depending on which USB port you connect the device to. Then the port name will look like /dev/mydev/Com1 or Com3 and so on

But this does not solve the problem of saving the pulse to the channel database when writing once per minute.

[manjey73]

Will the TP timer be enough for you, similar to how it is implemented in a PLC?

Ticks

Tp

Calling the formula Tp (Val(414), 10000) number of the monitored channel 414, time in milliseconds.
When 1 appears in channel 414, the timer output will turn on, after 10 seconds it will turn off for this example. The timer starts working on the signal edge, no need to hold 1 in the controlled channel.

The Ticks formula is used in all the timers I’ve done. The formulas must be added to the Formula Reference.

Use a VPN in your browser, which should help you get access to image hosting services

[manjey73]

It feels like you have IIS not installed correctly or the components in the additional Windows packages are not enabled correctly

[manjey73]

You can also run Scada Administrator in the Linux GUI. I ran it, but there are features, disabled drop-down lists due to problems with WCF as I understand it. In any case, you need to connect to the Linux server remotely, for example via RDP, but if there is a remote connection, then it is not so important how this happens. Toli in the graphical table of Linux itself, or with a Windows PC using Scsada Administrator

[manjey73]

InCmdTransferOptions Options that determine receiving telecontrol commands from a remote server
OutCmdTransferOptions Options that determine transferring telecontrol commands to a remote server

Is this it ?

[manjey73]

Does the client have all the PCs on Linux on the local network ? You can connect via TeamViewer to any PC on the network and download the project from it, as well as control its work. Why does the Scada server also need a graphical shell, if we are talking about Linux, although you can run TeamViewer in it or just use SSH. The scripts are located in the Communicator and Server folders, as well as in the scadaagent folder if there is a need to overload any of the components. Don’t forget to give them execution rights.

[manjey73]

You can link one way or another if you have at least one public IP. There is no other way. Even the MQTT server requires a public IP to be able to forward data from one subscriber to another.

[manjey73]

For some reason, the English site does not have this section or it is located in another place.

Use an online translator. Perhaps this will help you solve the problem of writing data from exel to Scada databases.

run Web on https

Read this topic and check how Apache is configured on a remote server, if in https mode you will have to do it by analogy for xsp4 or nginx
