Unsolved Snap7 and Qt ,PLC communication
-
path=c:\MinGW32\bin;c:\MinGW32\mingw32\bin;%PATH
mingw32-make %1
this is in .bat
and he said me
It is assumed that MinGW compiler is installed in C:\MinGW32 and its release is 4.7.2.
If not, you need to modify make.bat and makefile.
My mingw like you know in another folder.I will change it in the command line? and How?And I don't stil lunderstand how the makefile will be used in Qt,Am I missing something.And Thank you so much your helps,I learned very important knowledges -
Hi... i'm using SNAP7 compiled with mingw inside qtcreator... i can compile and also debug SNAP7 along with my HMI software...
If you can wait until monday i'll send you the complete project so you can have an easy start... -
Thank you mmiacca ,I can wait and also How did you manage it if you explain I will be so happy.
-
Are you able to do it with mingw 5.3.0?
-
Hi mmiacca ,could you give me an example ?,I need like you ssay,I need easy start
-
Hi (excuse my english please)
Here is the project file to compile a gui example with snap7, no libraries, all in one..

But the full project is here https://drive.google.com/file/d/1AWX3xe00D-WWrQwFGi18juR8KBkYkB7V/view?usp=sharing ... also the snap7 project... i'm using qt 5.9.2 with mingw... install it with default options...
Hope this help

Hi,
I'am intersting of this to integrate Snap7 with QtCreator,
I test your example "test1", it's compiled, but when run the "test.exe" : there is nothing !!
Have you an idea please ?
thank you in advanced -
@Daminos Nothing means? the windos has only two widget that show variables from plc, put a breakpoint in the following function...
void MainWindow::scan()
{
//ui->log->setText(logMessage);union U { unsigned char x[4]; float f; } u; int err = Client->DBRead(380, 160, 4, u.x); unsigned char aux; aux = u.x[0]; u.x[0] = u.x[3]; u.x[3] = aux; aux = u.x[1]; u.x[1] = u.x[2]; u.x[2] = aux; if(!err) { ui->value_0->setValue(u.f); ui->value_1->setValue(u.f); ui->value_0->setStyleSheet(""); ui->value_1->setStyleSheet(""); } else { ui->value_0->setValue(0); ui->value_1->setValue(0); ui->value_0->setStyleSheet("background-color: rgb(255, 0, 0);"); ui->value_1->setStyleSheet("background-color: rgb(255, 0, 0);"); // Connection int error = CliConnect(); if(!error) { }; } char valor; err = Client->DBRead(380, 151, 1, &valor); ui->checkBox->setChecked(valor & 0x01);
}

@mmiacca
Thanks a lot, it's worked now :D
I have another question please : are you tested this example with Logo_8 ?
Best regards, -
@Daminos good.... i do not test this with logo, only S7-400... do you change the cpu TCP/IP address and slot in the logo and in the code?
-
@mmiacca
I'll test that next week (because I wait for the Logo_8), I'll tel you if it's working ;)
see you !
Best regards, -
@mmiacca Hi mmiacca, I tested the connection code with the Logo_8, and it's worked ;)
Best regards,
Daminos
