    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 4.8.0.0. 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.

    Can anyone offer any insight?

  • thecolonel26 thecolonel26 posted a comment on discussion Engineering πŸ‡¬πŸ‡§

    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.
