We need to spread the devices on different physical lines of communication.

Could you share the wireshark logs that you received by scanning the packets ? If anything, there is the Allen Bradley Protocol.

You can check if this applies to Modbus using this link
Rapid SCADA Modbus Parser
However, you need to find the right start and end of the parcel in the TCP scanner

There is a similar task, but AB Micrologix is used, according to the description PLC data support Modbus, but it is used or not unknown. You must put the port watcher on the exchange between the PLC and the HMI panel to read the traffic between them. But not the fact that it will help. Plus, try to connect to the PLC with Modbus scanners.

Tell me, why do you then need to input 1 ?

[manjey73]

It is also necessary to transfer the configuration of the module settings. And also buy a license for the module on RaspberryPi

If the server is one of the main, the Rapid Gate is not needed.

If there are several servers plus one main server, then Rapid Gate is needed for each slave server and the corresponding number of licenses for each Rapid Gate is required.

A large diagram is specified without Rapid Gate

On the site your GSM modem can establish a connection via VPN channel ?

See Dat files in folders c:\SCADA\ArchiveDAT\

The data can be viewed using the Server application

Divide formulas into several channels. If the formula returns double, you can use one formula inside another.

for example

NOT(OR(Val(100), Val(101)))

public double NOT(double val)
{
    bool boolVal = val > 0;
    return Convert.ToDouble(!boolVal);
}

[manjey73]

Logical And

public double AND(double in1, double in2)
{
bool q = false;
bool i1 = in1 > 0;
bool i2 = in2 > 0;
q = i1&&i2;
return Convert.ToDouble(q);
}

[manjey73]

Judging by the logic you want to get logical OR ?

Add formula to formula table

public double OR(double in1, double in2)
{
bool q = false;
bool i1 = in1 > 0;
bool i2 = in2 > 0;
q = i1||i2;
return Convert.ToDouble(q);
}

Use in channel OR(Val (n), Val(m))

1. to do this, you must have an external static IP address for your server (router)
2. Perform the necessary router settings to access your services from outside

If this is not possible, use third-party services such as TeamViewer and others

Remote access is already a task of IT sphere, not Scada as such.

For example I have a dedicated static IP address. I connect to my router VPN client and see the entire internal network as if I was connected inside the network via Wi-Fi and moreover, the IP address on my phones to determine the third-party services becomes the same as when connecting VPN traffic begins to pass through my home router. Sometimes it is useful for sites that require access settings from certain IP addresses and will ignore you if the addresses are carrier-based.

KpModbus_test

Try this library. If your device does not respond due to zero ID, it should work. In the future, Mikhail promised to add an identifier change in the release version of the library.

If so, this is the second device that does not accept a null request ID.

Still you have the difference
00 25 00 00 00 06 01 03 00 00 00 0A
00 00 00 00 00 06 F6 03 00 00 00 05
