error modbus rtu and tcp

[Godra]

What are those other errors you have in Immediate Window, prior to the error in your picture?

If you set this driver's DisableSubscriptions property to True and run the program, does the window show at all?

[abdala]

When the value changes, the program does not run

This problem exists even in previous versions

You have tried changing the value and the program does not work

[Godra]

If your program doesn't run when you set this driver's DisableSubscriptions property to True, it means that something else is not working properly.

Can you take a picture of Immediate Window errors (extend its size to fit all the errors)?

[abdala]

This error does not always come but it is present in all versions of the program

What is your Facebook account to communicate with you

[Godra]

I don't have a Facebook account.

This forum communication should be sufficient to help resolve the errors.

If you remove the driver all together from your project and the program still doesn't run then that should indicate problems with something else.

[Godra]

Here is a picture of the form that I just deleted all drivers from.

It still runs and the controls show the error.

Add ModbusRTUCom1 and you will see what song

DisableSubscriptions=true

Do not read

What controls do you have on your form? There is a control that is subscribing prior to OnCreateControl. You could begin deleting controls until the error goes away to see which one is the culprit.
