    I am having trouble verifying a RSA PKCS1.5 SHA256 signature given a message, the signature as a hex string, and a public key as a .pem file. Here is an example of how I am trying to verify a signature using the CmpCrypto library in CODESYS V3.5.15: FUNCTION AsymmetricVerifyMessage : BOOL VAR_INTPUT sMessage : REFERENCE TO STRING; szMessage : ULINT; abySignature : REFERENCE TO ARRAY[0..255] OF BYTE; szSignature : ULINT; abyPublicKey : REFERENCE TO ARRAY[0..291] OF BYTE; szPublicKey : ULINT; END_VAR...

    Good afternoon, I encountered such a problem, the PFC200 controller (750-8208) has firmware 03.10.10(22) installed. Before that it was 19. Installed target Codesys SP 19. In the license manager, I can not install, it writes an error. Maybe someone faced such a problem? Thank you.

    Hi Barton, I am new to Codesys/Twincat and i have a similar kind of problem. Created my own visualization object and (use Visualization) chnaged it to NUMPAD type. I have to do this to change the Font on the NUMPAD to make it better visible. Everything works like the Visudialog.Numpad except the limit check that changes the min/max labels to red color when an input variable boundary check fails. Can you please guide me what went wrong with my chnage.

    Hello @student-t we can't solve the problem in the Visualization... I spoke with an employee from Codesys and he told me we shall impliment the event directly in the plc code... There is a FB who can handle this event. you can look here: Click

    Hi, Is there any documentation on the VisuElems interface IVisualisation? I want to get an understanding of the methods used in this interface, but i can't seem to find any links in Codesys Online nor in the Codesys Development Environment. Best Regards.

    Why is IDialogManager.OpenDialog Obsoleted? It says to use VisuUtils but VisuUtils is an incomplete interface as it is designed to be called continuously and not be called from the Visu_Task. Am I missing something or is Codesys intentionally removing capabilities?

    I want to get the name of the current task (As a string) that is executing a block of code? What is the easiest way of doing this? I have tried looking though the help documents but I am not finding what I am looking for.
