Briefly here https://rapidscada.org/device-drivers-development/ for english

Also use the source code of the project and the source code of the drivers from the users. MQTT Driver, Raspberry PI 3 Driver and others. Links can be found under http://demo.rapidscada.net/plugins/Store/Store.aspx

Better yet, if you get the udev rules then you will be able to name your USB-RS485 e.g. /dev/mydev/COM1 and not to pay attention that reboots it may be ttyUSB1 instead of ttyUSB0

[manjey73]

yes

You need to implement Modbus slave device on Arduino

I used a relay Board that is controlled by a minus. Therefore, for convenience, I’ve done inversion of control commands and control. If you use this fee-free formulas then 0 will turn relay 1 off relay

After you have configured the Communicator and transferred the data to the Raspberry Pi and rebooted scadacomm, you will see the kpXXX file in the folder ScadaComm\log.txt, which you have attached to GPIO channels.In it you will see the table included with the numbering of gpio signals. Use this numbering in the input and control channels

I created channels manually, because this mechanism is not implemented in the driver, if I can judge correctly.

No, it is not Modbus, you have to make similar settings in the administrator of Scada for GPIO.

You must set the checkboxes to change direction to OUT. On the idea of under such a a combination of will are engaged physical contacts 3 and 5

Have you read the description in English from the link above ?

Executed the command sudo gpio readall ? The given command will display the table of numbering of the contacts in BCM format and GPIO format. When you configure channels on Windows, the channels are numbered in BCM format. The output of this command you can understand which pin number corresponds to bcm numbering.

https://i.stack.imgur.com/h4rgc.png – It is necessary to focus on the BCM numbering

Can you catch and fix a screenshot ? Just online translation I do not understand what you mean ?

[manjey73]

double Scaler (double input, double in_min, double in_max, double out_min, double out_max)

{
double out1 = 0;
double out2 = 0;
double output = 0;
double diff = in_max - in_min;

if (diff != 0)
{
if (input > in_max) out1 = in_max;
else out1 = input;
if (in_min > out1) out2 = in_min;
else out2 = out1;
output = (out_max - out_min) / diff * (out2 - in_min) + out_min;
}
return output;
}

This site automatically changes the minus sign on the dash. Try to rewrite the formula from the code or correct hands.

The entry of the formula seems correct

[manjey73]

When you start Communicator and Server, it does not open the program window, but it starts minimized and its icons are located in the system tray

[manjey73]

Communicator runs in the system tray, we take account of it.
