post a screenshot of the ladder and the error message. I'm not able to have a lock at your monitor actually :-)

Hey thank you for the reply dkugler. I am sorry if this seems like a stupid question. I have the use current visuvariable checkbox enabled. I can see the string names of all my visualizations. I am trying to use ladder logic to be the anser to the button press using "VisuElems.CurrentVisu := 'MainScreen';. This returns an error. Any idea what I am doing wrong or could you point me in the right direction for fixing this. Thanks,

Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

I'm searching a way to print several projects to PDF, in order to correct student exercises. I'm able to open the printing dialog box using system.commands["print", "print"].execute(). But I can't find the prompt names in order to complete the printing with the dialogs Do you have any way to do that?

Here is a screenshot. I really do not know how to format the variable exchange you are talking about.

Can you give me an example on how this should look like?

Thank you for the response! It's a path I had already considered, however, while it has always worked for me on inputs, it doesn't on outputs, because if I enable the option to update all IOs at every scan, the IO tasks overwrite each other. However, I have found something very interesting which I am posting below.

CODESYS Control for Raspberry Pi MC Does CODESYS use its own native driver for I2c? I have a python script communicating with a device simultaneously with a CODESYS doing the same. The bus is not saturated. But I get many read errors
